Standard method for lubricating the bearings of big waterpower generators is to keep oil moving under forced circulation between the bearings and a cooling system which keeps the oil from overheating. The bearings of the Grand Coulee monsters will operate in a bath of oil containing its own cooling system in the form of immersed water pipes. Thus water will be pumped but no oil-cutting down piping and maintenance costs and reducing leakage hazards...
Suggested for adults: 18 ounces (about one loaf) of whole wheat a day, for carbo-lydrates; two-fifths of an ounce of salt, tor maintaining the water balance in body tissues; the same quantity of brewers' yeast, for vitamin B; one-twelfth of an ounce of cod-liver oil, for vitamin A; half a lemon twice weekly, for vitamin C.

If lemons or oranges...
...companies are experimenting with rubber-laminated walls for houses. A section of rubber paving in Akron's East Market Street that has lasted ten years points to a lucrative field if crude rubber prices ever fall low enough to compete with concrete. Rubber is vulnerable to oil and sun, so scientists have developed rubbery synthetics like DuPrene which are not. Such new products as Goodyear's Pliofilm and Goodrich's Koroseal are beginning to threaten Cellophane as packaging material. From rubber conveyor belts (Grand Coulee Dam has one 10,000 ft. long), the industry expects to make...
