Hul. large .seale introduction of machines didn't solve ail problems. When the department's engineers launched a study of brooms and broom construe!ion, the seemingly (.'heap vegetable libers palmyra, bass or split, hickory were actually found to hi' quite cast.lv.

In addition, ihe plaslic, used as "broom .straws." displayed excellent (lex life and bead recovery: resisted solvents and chemicals, including alkalies: and was. unalhvied by gasoline, oil or other pet solemn produels. Initial cost, of nylon was far higher than palmyra, but the tough plastic zoomed New York's mileage per broom I mm i to to 2 .<!()() sweeping miles.

How well we succeeded depended on the cart; with which the operator used his equipment," Accordingly, in IOperations instituted a train ing course for every sweeper driver. Run continuously since, the course emphasizes that the operator deter mines his broom's longevily by the pressure tie exerts upon it. Under the aegis of flu: American Public Works Association, this training course lias now been made into a 20 minute color movie, "Adjusting flu* Hi reel.

Example: one recent review of all cummin lilies* found Long Beach. Calif., Newark, N..I,. and Lake. Poresf, 111., averaging 2,1*00 ti.OOO miles per broom; Vernon, Calif., got 4/KID miles. But several cities logged as little as H00-1,000 miles. '`When mileage drops, we have little doubt that brooms are improperly adjusted," says I loward Payne of Plastics Depf.'s Technical .Service Laboralory. "But we're .also aware that other variables all'cet broom wear. For example, one city may have .smoothly paved streets, another bricks or palehed concrete. One sweeper may be at work downtown brushing up light, street litter, while another in the suburbs is digging washout mud. In such irases, wear rates are bound to vary. Eventually it dawned on us that perhaps (he answer was lo fry to tailor brooms for specific jobs or sweeping conditions."

Notable among ihe chemical materials are urethane polymers, first used several years ago as emck1`csislaiif finishes for patent leaflici'.

We then worked up this type of leather in the necessary weights, learned how very dose our production control had to be and have been very happy ever since.. We. fed that we're doing something distinctive, something that, can only be done with `Adiprene'." Where color is concerned, the leather industry is of necessity both a leader and a follower.

Spandex, like nylon or rayon, is a generic term for a fiber of certain chemical composi tion. It is designated by the Textile Fiber Products Identification Act as an elastomeric fiber in which the fiber-forming substance is a long-chain polymer consisting of at least 85 per cent segmented polyurethane. Unlike most other spandex fibers, which consist of one filament, "Lycra" is composed of several filaments combined into one fiber, Because of this form, fiber break age from sewing machine needles is small. Rubber elastic almost always is covered by such yarns as nylon or rayon before use. "Lycra" can be used bare, permitting savings in both weight and cost. Because it can be dyed, there is a significant reduction in the problem of "grin through"-- the visibility of an undyed elastomer core through a dyed cover. Girdles made with "Lycra" and color coordinated, with other lingerie are proving especially popular. Oik - reason for flic long delay in completing a com mereial plant, is that "Lycra" is made by the most complex process ever undertaken b.v Du Font in the production of a textile liber. Bui .stubborn production problems that, plagued the fiber's early years now have been solved, opening the way for supply to catch up with demand.

Here, at an elevation of -1 .(>()() feet, tin imaginative former Virginian named R. II Cohurn is giving tourists li close-up look nl life as it was lived on the frontier a century ago. 1 .opping off the peak of < iliosl. Mountain, Cohurn has created four aulhentie pioneer villages: Western Town, Mining Town, Indian Vi Huge arid Mountain Town. Visitors pan gold; witness a hank robbery; walk among redskins performing tribal war dances, and dine in a replica of a frontier saloon. To climb backward to the past, tourists clamber aboard four cage like rail cars and ascend d.-lG-t feet, 1,200 of winch seem almost vertical. Three fi.OUO-jxmud cables pull the ears up grades ranging from :S0 lo a dizzying 7(>. I per cent. During the park's maiden season in 1961, the t?2(HI,U(K) incline, exhilarated visitors hut exasperated maintenance rrews. To minimize cable wear, the in rline was sfurlrled with 1 Rti sofl melal rolls over which the cables slid. 'I'he cable:; lasted; bill, the rolls wore out. At points of severe stress near the pinnacle of the in cline, for example, rolls had to he changed every couple of days. In addition, there was a continuous scineal of metal grinding metal as tin* taut, cables cut groovers in the rolls. The soltilion to both problems emir from a park visitor, who, with his family, was enjoying a week end outing from his job at Payee Soul hern Division ol Payee Cnrp,, a Waynesville, Nik. thm with extensive experience in making textile and steel mill rolls. His (imely ride on (lie incline resulted in a suggestion lisa I park management try cove rim' I he soft metal rolls with I hi 1 'out neoprene. "Not only cl id neoprene provide silent operation; it also immediately proved it would last longer than melal rolls," says Bill Branson, Payee roll supervisor. "In places where metal rolls wore out in four days, neoprene lasted n month. An time w< nt on, it botanic clear that, neoprene-coaled rolls lasted about seven times longer than plain metal. Whal's more, neoprene gave the additional advantage of resisting lubricating greases and oils." L.if .I winter, all the guide rolls were, covered with neoprene by Payee in prrparal ion for the eurt'enl four is I season in which park managemenl estimates nearly one million passengers will take the high climb back into history on the precipitous incline. 12 .. .If...he., .led.a. modem ...army,....Napoleon.

I I isiorians and oilier academicians have long la mented tin: serious gap in U.B. annals caused by the irnnvaliability of business records wbelber due to actual loss or pas!, willful denials on the part of businessmen themselves. Dr. Paul I I. Buck, director of the ,1 harvard University Library, said recently: "The tnulf iplicatiini of materials accessible to scholars in most range's of history has accentuated the pitiable inade<|iiac_y in the field of business history. We nob' that, observers from abroad anti historians at home for more than a century have celebrated as a major, if not the major. American achievement- its business enterprise. But the fact remains that, in most general accounts of American history the businc`Human and his activit ies have been presented in sinister terms. The result, is a scandalous situation im peratively in need of correction," Steps to help make such a correct ion have been taken by the1 I'jleuthrrinn Mills Hogley Boimdation, a nonprofit Delaware educational corporal ion. The foundation has I (reserved the original Du Pont powder mill area on the Brandywine as a historic industrial site: developed the I lagley Museum, devoted to early American industry; sponsored, a fellowship program at the University of Delaware; and has now instituted till' Kleutheriaii Mills H istovical Library. Tlii` library is designed to serve ns "a center for scholarly research in the business anil industrial history of the Middle Atlantic stales area, which has exerted an important influence on the development of the American industrial economy for 2f>0 years." 'Flic library's sialT is collecting business records from the area, as well as related imprint materials,, with special emphasis on the nineteenth century. From time to lime it publishes guides to mmuw ript collect ions and textual editions of significant scries of its documents. Dr. Richmond 1).

After a good many leais of dill'erenl weaves and linisheK, he liar rowed his field lo two fabrics.
