Asbestos-Cement Pipe, In Addition to Being Highly Resistant to UnderGround Corrosion, Is Free of Tuberculation and Excessive Ground-Water Infiltration. Added Up, These Features Mean Long Useful Life

Glass, Material of Many Uses, Has Extended Man's Sight Into the Far-Off Universe and Into Microscopic Worlds. At the Same Time it Has Served Utilitarian Purposes in the Home and in Industry. Strangely Enough, it Was One of the Last of Present-Day Materials to be Adapted to Mass Production Methods and Hence Put to Wide Use

Asphalt in Varied Consistencies, Distilled From Petroleum, Surfaces Many Thousands of Miles of America's Highways. Quickly and Economically Laid in the Molten State, it Forms a Resilient and Flexible Road-Bed Whose Cushioning Surface Wears Long Under Constant Use

Liquefied Petroleum Gas, Because of its High Thermal Efficiency and Adaptability to Convenient Storage and Transportation, has Come to be an Important Factor in American Economy, Both Domestic and Industrial. Its Uses are Widely Varied and They are Increasing Rapidly

Airplane Engines, Operating at High Temperatures, Need Strong Oil Films to Protect Moving Parts. Careful Research by the Petroleum Industry Has Produced Lubricants that not only Resist Deterioration under Severe Conditions, but also Carry Away Heat from Pistons

Hydraulic Devices Provide Resiliency and Flexibility for the Complex Machine Tools of American Industry. The Oils that are the Lifeblood of These Hydraulic Systems Have Been Treated by Petroleum Refiners to Give Qualities Needed for long Service Under Difficult Conditions

Temperature and Humidity Control in Large Buildings with Many Small Rooms Has Been The Great Problem in Air Conditioning. Now a System Has Been Developed Based on High Pressure Flow of Conditioned Air Through Small Pipes, Eliminating the Space-Consuming Air Ducts of Earlier Methods
