Speed was why Todd and Kaiser got together in the first place. When the British in 1940 handed Todd a $100,000,000 rush order for 60 freighters, Todd was already working overtime on its repair business, needed new ways to build the ships. Kaiser, rapid-fire builder of Boulder, Bonneville and Grand Coulee dams, was the man they needed-and got. He worked 16-hour days, borrowed whirler cranes and other machinery from Grand Coulee, pounded between California and Washington commuter-fashion. Four months after Kaiser started, bleak mud flats were lofty ways. In January-13 months after...
...perfect 20. Then they took a face from one photograph, a sky or a piece of building from another, joined them together like pieces of a mosaic, and enlarged the results until they were several times life size. The photographs came from U.S. scenes as far apart as Boulder Dam and Vermont. The battleship at the top came from the picture files of LIFE; airplanes came from the Paramount picture I Wanted Wings. The California farm worker at left glances back at a caterpillar tractor from Washington which has just passed over a Montana wheat field nestling at the foot...
...them contain the mineral in the wrong form for easy separation: manganese dioxide. But two new processes developed by the U.S. Bureau of Mines are on the point of making low-grade manganese oxide ore a useful citizen of steel metallurgy. Last week in three new pilot plants at Boulder City, Nev., where oxide ore beds adjoin Boulder Dam's cheap electricity, manganese's first citizenship papers were being signed...
...additional process, now being perfected at Boulder City, is electrolysis. The oxide is put in water with a solvent and a current is passed through the solution. The metallic part of the dissolved compound becomes a positive ion which migrates to and accumulates on the negative electrode...

They voted a $220,000,000 bond issue, and in 1932 got RFC to help them sell the bonds. With a PWA loan, they started work on the aqueduct, which runs from Parker Dam, 155 miles south of Boulder Dam, to Lake Mathews, near Riverside. With the world's deepest dam foundation (233 feet under the river bed), Parker Dam stores water for the whole District system...
