GRUBER Just a short time ago it would have been quite impractical to trim bath towels and face cloths with glamorous borders or stripes of gold metallic yarn. And the girl who bought a bathing suit knitted with metallics definitely would have been the miss whose bathing suit never got wet. But in 1956 these things have become realities, thanks to the development of an Improved type of metallic yam made with Du Pont "Mylar" polyester film. The intro duction of "Mylar" into the field is the latest chapter A new metallic yarn, made by sandwiching foil or metallic particles between sheds of "Mylar" mid slitting to narrow width, is notable for moisture resistance. This permits use of metallic*! in bathing stilt and towels shown here. Unusual strength of the yarn mokes possible its use in luce,'top right. Other swatches show metallic yarn of "Mylar" in drapery and upholstery fabrics. 2 touch of "Mylar" fi* briHinnl hislttry #/' nu-lallir fabrics in the ii,(H)()-year history of the "Midas look" in fabrics. The textile industry ran now use glisten ins metallics in literally hundreds of new ways: in delicate silks and (ini' laces, gay col l oils ami wools; in shoes, rnitieoaf.s or knitted soils. Your home, too, can have curtains, drapes, linens and upholsiery fabrics wilh metallic:-; as practical as they are stylish. 1 low is all tins possible? Aren't metal lies heavy, harsh and impractical? Aren't they usually limited of necessity to costly dresses to be worn only on special occasions? 'Flic* are found in J)u Pont "Mylar". 'Hie transparent, film imparls a unique combination of proper ties fo finished metallic yarn. In one process, yarn manufacturers apply "Mylar" to each side of a thin sheet of aluminum foil, giving a film- Ibil-ftlrti lamination. Another manufacturing technique uses tiny metallic particles as the center of the "sandwich.'- In both eases, l.iie lamination is slit into narrow widths to become metallic yarn. Because "Mylar" is exceptionally strong, thin gauges can be used. 'I 'bus metallic yarn made with this film is so ft and pliable, adding a subtle note lo the fabric.. I'ixtrn strength and abrasion resistance mean smooth production on looms and knitting machines, even where tight turns are involved. In many is(unees, there's no need for sup porting yarn. 'Th in-gauge Mylar" yields up to 50 per cent inon.* to the pound than yams previously1 used, thereby holding down costs of I lie finished fabrics. In dyeing and finishing, the properties of mefallics made with the Du Font film read like the asset side of a. hr dance sheet. Since "Mylar" resists lie,at, chemicals and moisture, fabrics with this new type of yarn ran he dyed at the boil. They also can he piece, mercerized, pro-shrunk or (teal set. WAS! 14 If IT, TOO For consumers not. directly concerned with production or (hushing problems in the textile industry, the properties delivered to the yarn by "Mylar" tire still significant. Care is simplified. Fabrics with these improved me tallies can be ironed, dry cleaned and washed in a machine, ('ontrust these modern methods of achieving mefallic glamour fo those of yesterday... from .Bihlieal limes down I hrough the centuries... when gold and silver wore tediously hammered out by hand and cut into threads for the ornate gowns and robes of royally or elaborate clerical vestments. Today, mile after mile of metallic yarn is rolling off high speed machines fo meet the public's demand for bright, sparkling fabrics. Years ago, the glitter of metal lies was limited in its range of colors. But today's technology gives metallic yarns a rainbow range from plain f.o iridescent, from black, l.o silver. The desired shades are obtained by adding color to the bonding agent used in lamination, or by dyeing the sheets of "Mylar" before lamination. f IS At.'It! (THObSJ THY FA IS KM! Alert fabric designers, always on file lookout for new and exciting style possibilities, have been quick to recog nize the value of this new metallic yarn. Take the auto motive industry, for example. Because durability is as important as styling ill cars, yarns made with ".Mylar" have been adopted for upholstery in many of the ISJ56 models; still more mefallics will be evident in the '57 cars. Another new direction for mefallics made wil.li "Mylar" is in carpeting for the home. Up to now, mefallics for floor covering's have been reserved mainly for custommade, hand-woven rugs for resort hotels or showrooms. According f.o one leading yam manufacl nrer, 195(5 will be the biggest, year yet. for the glittering look, thanks to the many fabrics that ean now capitalize on the gliller of mefallics made with "Mylar". So keep your eyes peeled in the days ahead. J!' it glitters, chances are it's chemistry's newest contribution to the bright world of fashion. The rlecornl.iv<: uses of "Mylar"-..as opposed to the func tional side it displays in sound tape or electrical insulation - don't, end with metallic yarns. If, instead of slitting the motalized film into yarn, you laminate it f.o plastic coated fabric and emboss it, you have the lustrous material so popular now on the inside of automobile doors and in upholstery welting.

In file field of home furnishings, Pearl-Wick, Inc., is covering Hollies hampers with an al.f.raef.ive laminate of randomly scattered metallic yarn and squares sandwiched between a sheet of "Mylar" and a hacking material.

Many of the accidents now being studied by the Cornell researeh group involve automobiles equipped with such safely devices as seat belts, crash padding or .springproof door locks. While the number of such cases studied so far is too small to he statistically reliable, all indications point to "materially increased occupant safety through use of these devices,'' Cornell reports. (Chrysler started offering seal, belts as dealer-installed optional equipment just about a year ago. Ford followed with optional factory installation of belts on its new oars. Currently, seat bolts cun bo obtained for all makes. The belts have the wholehearted support of such organizations as the "National Safety Council, and several states are con sidering legislation requiring seat belt installation. Wide spread ncceptiinee is coming from stale police, insurance companies and organizations that operate auto fleets. NYMtlN BKl.TS STHOINC. ATTKACTIX K Du Pont nylon is used extensively in seal, belts. "Nylon has the obvious advantage of toughness suflieient to meet rugged requirements set by the Society of Automotive Engineers and the American Standards Association. In addition, nylon belts can be dyed easily with fast colors that, harmonize with ear interiors. '.This is important in overcoming consumer objections to the drab looks of sonic: belts and to the chance of clothing damage from hell, dyes. Also winning recognition for their part in safe packag ing of passengers are such equipment as crash padding (see next page) and safety door locks, the latter now stand ard on moat models. Contributing to the effectiveness of many of the new looks are resilient wedges of Du Pont "Zytel" nylon resin that absorb shock from slammed doors. Adopted several years ago, the self-lubricating wedges eliminate the need for grease that might soil paBiangera' clothes. No one, least of all the men whose work is back of the new safety devices, is suggesting that they are the chief means of cutting down the dreadful annual toll of highway accidents.

Called the "Mighty-Mite" Model T*(> Reining! on .Sind Driver, il complements the line of powder-actuated tools already manufactured by the company. Biggest ad vantages of the "Mighty-Mite" are its low initial cost and adaptability to low- volume fastening jobs. Five years ago Remington introduced its first powder actuated driver, a spade-grip tool that hammered nail like alloy steel studs into structural materials with the controlled blast from a .`ill caliber blank cartridge. Barge volume, builders were quick to give it their okay because it speeded fa stealing jobs, and smaller contractors found the tool h o .satisfactory they rented it by the day or week. SI\I,I.S I'OK s.i t.75 The new model, however, makes it possible for the small building contractor to afford his own stud driver and operate if. at. miiiiim.nn cost.. It retails for only $8-1.75. Tlie "Mighty-Mite" consists of three parts and weighs 8:!.i pounds. The operator loads it with a stud and a `22 caliber cartridge, then twists the upper section and de presses the lower part of t he tool against the work surface, exposing the tiring pin in the fop. A light, sharp blow with a hammer on the pm tires t he blank cart ridge!, sending the nail-like stud into the work surface to complete the fastening. The power loads are made with varying powder charger- to give the operator a wide selection for various jobs. Also available are 26 types of quarter-inch alloy steel studs, ranging from 1 to 3%j` Inches In length. Like its bigger brothers, the "Mighty-Mite" fastens steel or wood fittings to concrete or steel. Some difficult but typical fastening jobs it can do easily; light machinery to concrete; furring to concrete, brick or steel; lighting fixtures and outlet boxes to concrete or steel; television fittings to concrete or brick; shelves, racks, and signs to concrete, and wall ties to concrete arid brick.

When 1.1m: felt heroines saturated with the tillered material, it can lie cleaned more easily than a conventional material. This same fell constriiei.ion, impregnated with "Teflon" resin, also makes an ideal gasket material under hot cor rosive conditions that, common materials cannot, with stand.

Samples have held up in impact tests down to a tem perature of -32,(1" F. without, cracking or shattering. A whole new family of fabrics coated with "I,eel on" acrylic resin is being developed primarily tor the electrical insulation field. They combine good electrical properties with resistance to heal- and many chemicals. By varying tlie base .fabric, insulation materials are made; with dif ferent properties: 1. Fabrics of glass liber or "Dacron" polyester liber coated with "Loci on" have exits I lent thermal sta bility at temperatures up i.o 270T'. ami can lie used for extended periods up to 3tM)F. 2.

"Third relay on the firing line!" Tall Man was barking as I hurried inside. Nine boys and girls lifted polished Remington 22 caliber rifles from a rack, adjusted arm slings, and assumed prone positions on a row of mats before a line of paper targets 50 feet away. The Davy Crocketteera were in action. : "Ready on the right!" Tall Man's practiced eyes scanned the line of boys and girls, "Ready on the left!" He paused momentarily, "Load!" . . . Gleaming rifle cartridges clicked into chambers and bolts snapped shut with sharp, almost military, precision. "Fire!" Shot after shot split the air. "Cease fire!" The kids scrambled to their feet and dashed to the paper targets. "Wow-ee, I got 41 out of 50!" whooped Butch Liikar, "What did you get, Steve?" "Forty-six! Beteha I get the Sharpshooter medal pretty soon." These youngsters, with the thorough approval of their parents, are having real fun and at the same time learning how to handle firearms safely. The cost is low. For the price of a matinee ticket they can buy enough Remington ammunition for a two-hour shooting session at the Davy Crocketteer Junior Rifle Club, Back of the dub is Tall Man--Norris G, Kenny, onetime rifle coach'in a military school, "A boy and a gun," he says, "are as inseparable as the stars and stripes in Old Glory. An attempt to separate them would be undesirable. What kids need is training in the handling of firearms." NO "BANC, BANC" Air Force Colonel James T, McKee agrees. "My kid," he says, "sees guns firing In every direction on TV shows. I don't want him to think that lie can pick up a gun and go `bang, bang' with it at anybody. If he is to have a gun--and he should have one--I want him to learn the safe way to use it. That calls for adult instruction and supervision," That is what these boys and girls between the ages of 8 and 15 are getting at the Davy Crocketteera' rifle range. Before starting target practice, Instructor Kenny required each member' to learn the various parts of the rifle, memorize the National Rifle Association's eight rules 14 for widely in handling and firing a gun, and master (.lie four .standard shooting positions prone, sitting, kneeling and si uncling. lit! also si lowed a eoior mol ion pint ore, obtained from Lhe National Riile Association, in which Trigger Happy Harry did precisely what, one should not do with a gun. It was only after the safe handling of firearms had be come a habit with the youngsters that Kenny allowed them to shoot at targets. The Crocket leers' range is 55 feet long and 40 feet wide, with the firing line 50 feet from the targets. This leaves a space of 15 feet behind the line for benches, t'ille racks, tables and other equipment. The backstop is a steel plate a hall" inch thick. It's set at. a <15-degree angle to the door, causing bullets to drop into the sand at the base of the pi all?. Target shooting is a source of boundless enthusiasm for the young marksmen. As they become more proficient., they are eligible for graded awards.. Marksman io Dis tinguished Rifleman.

In addition, BL-353 leaves no objectionable odor and does not discolor the foam. Perhaps the biggest technical advantage of chemical blowing with BL-353 from the foam producer's viewpoint is the close control it gives him of cell size and density, whether he makes Ms product in open molds or in closed molds under pressure. As competition in the field steps up, this control of the foam's physical properties is likely to become mote important. SMALL PRODUCERS IN FIELD A nominal investment in equipment, especially for foam production at atmospheric pressure, is another plus for the chemical method of blowing vinyl. This accounts for the fact that relatively small concerns are beginning to show up on the roster of foam producers. Blowing foaip chemically is quite a bit Mite making a coke. The pksttsol, a mixture of vinyl resin, plasticizer and other chemicals, corresponds to the flour, milk, eggs, sugar anil shortening. A chemical blowing agent acts as the baking powder, except that it generates nitrogen instead of carbon dioxide. As the mix fa heated, the gas is released. The cake of plastic foam rises and Is cured in its puffed-up form. The excellent cell uniformity of diemically Mown foam is important in many applications. Crest Chemical Industries Corp., of Brooklyn, for example, sells its foam to .makers, of padded, vinyl .belts, and . handbags, quilted slippers and so on, in the form of sheet up to an inch or more in thickness. The sheet is sliced--like cheese--from a larger slab of foam. Crest's customers take advantage of the thermoplasticity ofvinyl by heat- sealing the sheet stock between layers of vinyl film or rayon satin to give their products body. Irregular and oversized cels would show up as holes in thesheet, presenting obvious problems to the user. Another low-density sheet foam made by Foam King, Inc., of New York City, is being promoted as an interlining in shoes, among other end uses. The interlining is open-cell foam--that is, the cells are interconnected. Foam King also offers closed-cel foam in a wide range of densities. One grade has been introduced as an improved shoe sole material. Both open- and closed-cell typos are Mown with BL-353 at atmospheric pressure, Foam King reports. Closed-cell vinyl foam also can be pressure-molded with the Du Pont chemical. Vinyl net floats, one end product in this category made by Linen Thread Co., Inc., of Paterson, N. J., are said to be a decided improvement on traditional cork floats for fish nets. More durable than cork and less susceptible to waterlogging, the vinyl floats also weigh about half as much. Since a big purse seine has as many as 3,500 floats, the weight saving Is impressive. Menhaden fishermen off the last Coast, Linen Thread reports, are able to handle their nets at least 25 per cent faster since vinyl floats were adopted. Foam producers are optimistic about the future growth of vinyl foam in the marine field. They have their eye on ring buoys, boat fenders, boat cushions and other products where the buoyancy, durability and fire re sistance of closed-cell vinyl give it an edge. In addition to the end uses we've mentioned, vinyl foam producers are competing for a share of the market for instrument panel padding In safety-conscious Detroit. " 'Their'products' also' are "going into" seat' cushions, auto mobile armrests and sun visors, padding for athletic equipment, gasketing, aircraft insulation, toys, insulated footwear and bath mats. ' Some authorities believe a rigid foam of low-density, closed-cell vinyl would make an Meal floor covering material or even load-bearing structural members for aircraft and buildings. Other hot prospective uses for vinyl foams: backing for upholstery fabrics, insulated clothing, decorative wall coverings, valve floats and various novelty items.

One good bet is to stop leaftioppers with "Marlate" 2-MR insecticide. The crop is safe to cut or graze a week after spraying. More important, it may have up to 25 per cent more pro tein and twice the Vitamin A content of 'hopper-damaged alfalfa. Applied early in the spring, "Marlate" con trols spittlebugs, too. Application of "Karmex" W herbicide in vineyards this past spring is cur rently paying off in desired control of many seedling annual weeds, such as crabgraes, foxtail, pigweed and rag weed. This new use for "Karmex" was recommended following field trials in Important grape producing areas. For weed control In potato fields, a single spray application of "Karmex" 1TW herbicide at planting time is proving effective for up to six weeks. Painting metal roofs and metal siding white is an excellent way to keep livestock and stored crops cooler these hot summer days. The white surface provided by "Dulux" Tank White reflects the sun's rays instead of ab sorbing them, cutting down on tem peratures underneath. Ixtra attention to disease control is one of the main reasons why some tomato growers make money while others only break even, a recent study shows. Yet even the best spray and dust programs represented only about seven per cent of production costs. Growers all over the country find that they can check anthracnose, blight and other diseases by spraying "Manzate" maneb fungicide within two weeks after the first tomatoes have set and every seven to ten days throughout the season. For supple mental nitrogen feeding, "NuGreen" fertilizer compound can be combined with "Manzate". .vv-bib: Hot, summer sun is the worst enemy of hose ustxi with insectieidoand furli Ib'.or .sprayers.

Unlike many industrial develop ments that suffer detours on the road to market, ibis one moved from conception t-o maturity in less than Uvn years. The idea was born in December. fOh-f. when St. Regis officials attended one of a series of Du Font -sponsored meetings aimed at ini.roiiui.-ing new eltemLeals of interest in the paper industry- "Ludox" was one of the products, and Lane si ill has the note's he took dial day `improves adhesion and si ip-resistance id' paper surface." At St. Regis' request, two I hi Font technical men journeyed to the Hi. Regis mnliiwntl bag factory at Pensa cola to help with experiments. "Ludox" alone didn't da the trick, Lane said. The present. "Lustergrip" coaling was worked out lv St-. Regis chemists in subsequent months. "W e also worked closely with l)u Font in introducing; the da of sewing multiwail bags with `Super T<n'dtir,-s' high tenacity- rayon yarn," Lane recalled. "We believe lids new development is one that will prove just ns sat ist'aelory from I he point of view of both makers and users of multi wall bags." In addition to the grade of "Ludox" used by St. Regis in it-s new- antiskid coating, Du Font is now marketing two others.

It's logical that: this should happen, lor the Company's extensive research prog rum is one of its best known features- Even so, when summing up tile personnel and facilities at: the disposal of just, one Company research unit, that, of the Petroleum Chemicals Division, 1 was a maxed by ihe si/.e and scope of the elfort. * Important products made by this Division include ielraethyl lead and oilier fuel, lube oil and grease additives. Some 1150 persons are on the laboratory team 25  t , i i k i > ; i; j ` w i i >: f\ j ` i !I!s>>5s : ` . `: it > J h ti t* shows clfects of different fuel additives. For instance, dos ii given additive mu m: smoke or dog nozzles? working on problems directly related to products for the petroleum industry, A sizable number are concerned with Improving the process for manufacturing tetraethyl lead--work that already has resulted in a new continuous process. Another group conducts fundamental re search to find even better fuel additives, and men with an eye to the future probe the mysteries of combustion and lubrication for the engines of tomorrow. Other projects include fundamental studies of jet fuel combustion and lube oil additives. Studies of engine deposits, preignition, spark plug fouling, valve burning and octane require ments also are carried out. Applied research is conducted on anti knock compounds, sseavengers, anti-preignition additives, fuel stabilizers, fuel oil stabilizers, diesel and jet fuel additives, gasoline antioxidants, fuel dyes, metal deactivators, and additives such as inhibitors, detergents and compounds to improve the viscosity index of lube oils, TRAINED MEN BACKBONE OF RESEARCH The greatest strength of this research effort lies not in excellent facilities nor the wide scope of the research work but in the men conducting the program. The variety of graduate and undergraduate degrees they hold is one measure of this. Another is the tremendous range of specialization. Not only are there men experienced in problems of petroleum chemistry but there are metallurgists, mechanical engineers, physicists and electronic specialists. Research authorities throughout the Company are available for consultation on such subjects as dyes, detergents, polymers and a dozen unrelated fields covered by Du Font's diversified chemical interests. Only a research-minded company could field such a team. Since its founding 160-odd years ago, Du Pont has considered research essential to progress and steady growth. Today more than 5,000 technical graduates and an even greater number of assistants and technicians are engaged in research at the Company's more than 60 research and development laboratories. The Petroleum Laboratory Is an important link in this chain of activity, serving the interests of the petroleum industry and Its customers, the American public. Company libraries arc equipped to serve researchers. For example, they contain some 200,000 patents and more than 700 current technical publications and trade jourmils, as well as thousands of copies of technical boohs. RIDERS IN THE SKY A cations blend of lots. train and airplane, the monorail soars ororft rod mi nylon cord tires Imagine riding l.o work in ;i coach 00 feel above lhe street, reading the morning | in per in sound (iro<if, air-condii ioned comfort.

The rail dips dose to the ground at stations to permit ground-level loading, then soars upward again. The car has been operated at 50 miles an hour, hut the manufacturers say that in actual service if could operate at twice that, speed. The suspended monorail is not, new. An all-steel system has been operating in Wuppertal, Germany, since 1903. .But t.lie German monorail is outdated, and runs at approximately 25 miles an hour.

Somewhat the same principle is applied by fleet owners who let their attractively painted trucks deliver a selling message for them, A striking design, used tastefully and uniformly on a fleet, may never compete with a pretty face, but it's an easy and effective way of letting the public know who you are and what you have to sell. As a supplier of finishing materials to fleets and independent refinish shops from Tallahassee to Tacoma, Du Pont has helped many fleet owners choose billboard color schemes for their trucks. The toughness and lasting gloss of Du Pont "Dulux" enamel have helped keep these same rolling advertisements fit for the public eye, Anheuser-Busch, Ine., one of the firms Du Pont has aided with such painting specifications, recently drew up a colorful design for the trucks that deliver "Budweiser" beer. The St. Louis brewer sends detailed paint ing instructions, stencils and decals to local beer wholesalers who paint and letter their delivery trucks uniformly for camitry-wida recognition, "Painted in the new reel and white color scheme, there's no doubt a truck is a calling card to the dealer and a traveling billboard to the consumer," AnheuserBusch says. A distinctive painting plan can advertise just as successfully for a local firm, Harold Postma of Grandville, Mich., believes. The entire 1956 advertising pro gram of his II, F. Postma Gravel Co. is wrapped up in the striped paint job he's using on his 50 trucks. All are finished with "Duhist" enamel. Sites Silver Wheel Freightlines of Portland, Ore., unlike Anheuser-Busch and Postma, has no product to sell. But the 220 units of its imaginatively painted highway fleet are effective salesmen for the company's hauling services. A regular schedule of washing and refinishmg with "Dulux" enamel keeps the transports' appearance up to snuff, adding appreciably to the company's prestige in the area it serves. Two pointers from those who have been successful with the traveling billboard idea: 1. Make your design different, but keep it simple. It has to tell its story in a split second. .... ' *. say it "illi photos, turned out by the thousand on ilii Pont '"'Velour lilacId"1 plmfogmphle paper .... It was early December. Mont of the people in Fran Is fort., Kv., were gelling ready for Christmas. Four Frankfort, photographers, however, were thinking more about summer vacations. Busy making pictures lor a new publicity pro gram to illusl rah; Kentucky's louri.sl. attractions, they had 25.000 photographs to print in only 20 days. This might seem routine, even humdrum, to a studio with mass production facilities. Bui. Jim Warren, senior photographer of Kentucky's publicity division, had no mass production facilities. He find only three colleagues... lellovv photographers who doubled in the darkroom -..two enlarger.*; and two print driers. Yet Jim and his staff were able to meet the deadline and spend Christmas wi 1,1i their families without sending out a single print they weren't proud of. "(Quantity printing with limited facilities," nays Jim, "demands a photographic paper that has good speed, wide latitude, and is suited to last, easy processing. We were able to fill that print order and others like it with tin; help of just such a paper...Du I'oiif `Velour Black'." Moutycky, like every other state, is keenly aware today of the importance of tourist dollars. In 1048, real izing that appropriate, well planned photographs could aid punch to the state's story, the Kentucky Division of Publicity added a photographic section. The section serves the photographic needs of all state agencies, hut more than 90 per cent of its work involves supplying publicity photos to newspapers, magazines, the American Automobile Association and the state PI lam tier of (loin menus More than 400 periodieals receive Kentucky's publicity kits every six months.

INIIKH I OH OIIAI.ITV p a r \mo u n t "Because our prints are intended for magazine and newspaper reproduction," says Jim Warren, ``we need quality above all. A substandard printing job would jeopardize the success of our publicity effort. "We aren't as experienced in processing as regular darkroom men, and we're bound to make mistakes. Bui. the wide latitude of' `Velour Black' and its lint; photographic and processing properties give us the leeway and l he results we need." To be ready for orders like the one that hit at 1 Ihristrnas time, Jim Warren and his associates order 100,000 sheets of "Velour Black" at a time. That way, no matter how great the pressure for speed, they can be sure they're giving the moaf favorable picture of the Blucgrass Hl.ate 1.0 prospective visitors.

Campbell Chain Co., on the other hand, wants a tough, fast-drying finish for color-coding its new "Measure-Mark" chain. It's not unusual that these radically different requirements should have led both companies to Du Pont's Industrial Finishes division. Du Pont paint chemists, field service men and salesmen daily run the gamut from sinks to links. Tailoring finishes to meet the special needs of industrial users is the job of this division. Ten laboratories and hundreds of technically trained employes see to it that the Du Pont finish supplied meets conditions imposed by the user. The criteria are econ omy in application and maximum resistance to failure in service. Whether it's utility alone or beauty plus utility you're after in a finish, look to Du Pont for help in finding the answer. Cabinet of Beauty Queen "Vanette" vanity is finished with Du Pont baked enamel. Colors have been coordinated with those used by plumbing fixture manufacturers. Campbell "Measure-Mark" chain is striped with Du Pont lacquer every five feet to make measuring easier. The colors identify four distinct grades of Campbell chain.
