Later it was believed that his bones were removed to the Cathedral in Seville. However, in repairing the Santo Domingo Cathedral at a subsequent date, a lead casket was discovered bearing the inscription, "Cristobal Colon, Primera Almirante." This and other evidence have caused more credence to be given to the belief that the great discoverer remains where he had desired to rest. In the accompanying photographs are illustrated the tomb of Columbus, given by the Italian government, and the beautiful leaden box in which are preserved his last mortal remains. The mile-long pipe used in Dr. Michelson's experiments on the velocity of light the tremendous crushing effect from outside when the air within the tube has been excluded, and air tightness to make the vacuum possible. Fourteengauge corrugated ARMCO iron pipe, 3 ft. in diam eter, has been used, the corrugations greatly increas ing the strength. The pipe is double-riveted and sol dered. and specially designed air-tight expansion joints connect the 60 ft. lengths. Approximately 1280 lbs. of half and half lead-tin solder were re quired for this job. The pipe was furnished by the California Corrugated Culvert Cw.upany. who did all of the soldering.

A hole is cut in the center of the pan bottom to receive the drain. Asphaltum is then brushed over the lower side of the pan and the pan placed on the shower room floor. It is pounded down well to fit the floor, which slopes from all sides toward the drain, and is soldered to the drain. The drain has small holes drilled in its wall just above the lead to receive any moisture that may accumulate on the lead after penetrating the tile floor. After the pan is in place, its upper surface is coated with asphaltum, and it is ready to receive the finishing tile floor. The wire lath on the walls of the shower room should be allowed to hang down over the turned-up edges of the lead pan. Coating the lead both sides with asphaltum paint is an added precaution, for water which has come in contact with concrete or mortar containing much free lime is likely to injure the lead if oxygen is present. When there is a step leading into the shower stall, as is The manner in which lead sheets are joined for use over large areas (above) the method of forming shower pan corners usually the case, the turned-up lead on this side is folded back over it before the step is tiled. If the room being lined is a larger shower room, or swimming pool, or some other area which cannot be covered with a single sheet of lead, ordinary folded seams should be made and soldered at the fold. This is also shown in an accompanying sketch. Industrial Laboratories Find Lead Table Tops Economical HE Anaconda Copper Mining Company uses Tlead extensively in its laboratories at Great Falls, Montana. Lead covers all tables and desks where acids are used, and hydrogen sulphide generators are also made of this metal. Lead-covered tables have been in use there for a good many years and have proven to be entirely satisfactory. The advantages of lead for this purpose are sev eral. It is highly resistant to the corrosive action of most chemicals. It is so easily worked and so low- priced that it makes inexpensive desk construction not only possible but entirely satis factory. In addition, the softness of a lead table top eliminates much of the breakage of expensive glass beak ers and consequent loss of solutions that may have required much time and Lead table tops in the Anaconda laboratories at Great Falls, Montana trouble in the making. This breakage is often quite considerable where hard materials are used for table surfaces and sink linings.

Batteries of this type are generally lyte. used to furnish auxiliary power when needed, for The C. R. Huntley Plant No. 2 of Buffalo General Electric Company has been built to furnish 60-cycle current for the City of Buffalo, N. Y., and incorpo rates the very latest developments in the way of equipment for the most efficient and economical pro duction of electric current from steam power. This battery was supplied by the USL Battery Corpora tion of Niagara Falls, N. Y. Extensive Lead Equipment in Rayon Manufacture Battery room in the new Huntley Station of the Buffalo General Electric Company emergency lighting so that consumers' power sup plies will not be interrupted, and to operate oil switches. They furnish power for automatic and central office telephone systems and large radio send ing stations. One of the outstanding advantages of the lead-acid type of battery is that the current can be put into the battery at low rates and taken out at compara tively high rates. Thus with a comparatively small generator and the proper type of storage battery, power is made available for emergency work, and the closing of large circuit breakers in powder plants where the rate of current required in amperes is many times the capacity of the generator. The battery at the Huntley Station contains 120 cells of 15 plates each. The plates are 10)A in. wide by 11/4 in. high, the positives being J4 in. thick and the negatives 3/16 in. The rated capacity is 532 ampere hours at the eight hour rate, i.e.. 66/4 amperes for eight hours. It will deliver 266 amperes for one hour to 1.75 volts per cell. The one minute rating to 1.75 volts per cell is 630 amperes; to 1.5 volts per cell 1,260 amperes. The plates are separated by the use of Port Orford cedar in connection with perforated rubber veneer. A special sealed-in construction is employed which eliminates spraying of acid and thus greatly reduces the maintenance cost of wood battery racks and WO large rayon manufacturers--the American TBemberg Corporation and the American Glanzstoff Corporation--located at Elizabethton, Tenn., have used more than 2,000,000 pounds of lead in the construction of their plants. In the production of rayon, highly corrosive chemicals are handled. Miles upon miles of lead pipe, ranging in size from /4 in. to 10 in. in diameter, transport the corrosive substances in the plants of these two companies. In addition, acid tanks, filter systems, spinning ma chines and other equipment required great amounts of sheet lead. The acid building of the American Glanzstoff Corporation, second unit, is entirely flashed with hard lead. This is to resist the action of acid fumes which would be highly destructive to other materials. The American Bemberg and American Glanzstoff rayon plants at Elizabethton, Tenn. f6] LIA25133 The Glanzstotf Corporation manufactures rayon by the Viscose process and has an annual capacity of 8,000.000 pounds of yarn, while the Bemberg Corporation uses the Cupra-ammonium process and has a capacity of 4,000,000 pounds, Lockwood Greene Engineers. Inc., of New York, were the con sulting engineers for the owners of these two projects, and O. G. Kelley & Co., of Everett, .Mass., and New York, were the installation engineers on all lead requirements in both plants.

An additional advantage of this type of marker is that the surface is not slippery either to the play er's foot or to the ball, so that there is little differ ence between the lines and the court surfacing. The lead tape described is the Spalding No. R.M and is the type used by the H. Robins Burroughs Co., Inc., in making their high-class Bursco red or green Fast Drying courts.

Phipps estate, Roslyn, Long Island sharpness under hard usage and add to the appear ance of the court, but must not interfere with the play. Old-fashioned canvas tape was a hazard to play ers, who often tripped over it, caused irregular bounces of the ball, and the tape was often torn, leaving great voids in the lines. Lime markers re quire much time and labor to keep them renewed and in satisfactory condition. Lead strips, \V2 in. wide and 1/32 in. thick, painted white with quick drying enamel, surmount these difficulties. They need only be repainted once or twice a year. They are installed so that they are flush with the surface of the court and are held down by hook-headed nails spaced at 3 in. intervals on each side of the tape. The softness of the lead allows the heads of the a Century Young IXTY-FOUR years ago, Hieronymus Mueller, S founder of the Mueller Co., made and installed the water service connection shown in the accom panying photograph.

It can be applied by any com petent decorator. The walls must be sized with lead f> V A New Panelling and oil paint (not flat paint), before the application of the lining cloth and Flexwood. After the Flexwood is on the wall it may be finished just as would any panelled surface, for it is real wood. It should be well sanded and then finished either with shellac and wax, brushing lacquer, fiat var nish, or stains. Although it is a comparatively new product, it has already found wide ac ceptance, and many homes, offices and public buildings have used it. It is also being used for finishing airplane cabin interiors, furniture, and many other purposes.
