To guard against this possibility, lead-asbestos mats are placed on the many foundations unde^ the grillages on which rest the column footing^/These mats consist of a bottom^layer of / in. sheet lead, on top of w'hich are placed, in order, sheets of 3/s in. asbestos board, No. 20 gage steel, :/s in. asbestos board and a second sheet of ps in. lead. The lower lead sheet is slightly larger than the rest and is bent up and over the top sheet to form a lead container for the other materials, and is soldered. Thus an insulating pad is formed which will stop the passage of vibration from the tracks up through the building steel, for lead is the only common metal which deadens vibration, which will withstand building loads, and, due to lead's great corrosion resistance, will last as long as the building resting upon it. This method of securing complete freedom from noise and vibration has already been success fully employed in New York for a number of years and is becoming quite widely used where buildings are erected in close proximity to railroad tracks and other sources of vibration and noise such as highway bridges. Above ground sheet lead is used for flashings on these fine buildings. Red lead protects the steel of the buildings, and the poles carrying the electric trolley wires, from rust and destruction. White lead in paint will be used to protect and beautify. In other ways, too, such as in lead-covered cable and in storage batteries, lead will find a place in these far-reaching improvements of the Pennsylvania Rail road in and around Philadelphia.

Shedd Aquarium, the largest aquarium in the world, made possible through the generosity of the late John G. Shedd, Marshall Field and Company's former president. The building is a magnificent and imposing structure, in keeping with its surroundings, and designed by Graham, Anderson, Probst and White, Chicago architects, for permanence. Lead naturally plays an important part in its construction. Built of white Georgia marble, it is literally crowned with lead, which will never stain nor discolor the beau tiful white stone. There are 320 feet of cast hard lead cresting 13 inches high around the edge of the roof and up the ridges of the skylight modelled to represent roll ing waves. This cresting required about 26,000 pounds of lead. Along the ridge-pole of the roof, over the main hall, is 115 feet of cast hard lead cresting three feet high representing sea-shells, weighing in all about 22,000 pounds. The skylight is constructed of lead-sheathed steel glazing bars, which will insure its permanence without attention or maintenance. And crowning the whole is t LIA25107 Ilf L a lead finial, a trident with fish and waves at its base, rising 16 feet 2 inches above the top of the skylight and measuring 6 feet 2 inches at its base. This finial is cast of 8.800 pounds of antimonial lead. In addition some 37,000 pounds of hard lead sheet were used for flashing and roofing purposes. In the interior of the building there are literally miles of lead pipe. All of the water used for the various kinds of fish is handled in lead pipe, ranging in size from one-half inch to six inches. All of the valves in this system are lead also. Some appreciation of the size of the John G. Shedd Aquarium may be obtained from the fact that it has a total of 132 exhibition tanks and 87 reserve tanks. There is storage capacity in the building for two mil lion gallons of water. One-half of this is fresh water from Lake Michigan. The other million gallons is pure ocean water brought from Key West, Florida, in 160 railroad tank cars. The Aquarium exhibits both salt water and fresh water fish, some in heated water and others in chilled water. It hopes, eventually, to number among its exhibits specimens from every part of the country as well as from other parts of the world.
