So long at America and its allies maintain a substantial lead in atomic energy development, their enemies are more likely to defer provoking all-out war. Atomic energy depends on the construction industry* as well as the science professions for its progressive, creative development.

BECK BttftfUM Manager GENEVIEVE MORRIS Assistant COVER The "highball express/' nickname for the 4H-ton steel ball shown on the cover hurtling through the reservoir area being cleared for the Hungry Horse Dam in Montana, was a "screwball" idea of two contractors--Wizson Ic Crowe. Inc., and J. H. Trisdale. Inc. of Redding. California. In executing one contract, they experier. ed delays from the snagging on stumps and rough terrain of tneir cables which were dragged by two tractors through the scrub timber in clearing operations. Then they hit on the idea of a big steel ball, equipped with swivels and jewels on tbe axle, and attached to the cable to keep it high o8 tbe ground. The axle rides oo Timken bearings, and lubrication is by tbe simple method of dumping heavy oil inside the 94-inch boiler-plate sphere. The contractors, pooling their ideas oo separate contracts covering an aggregate of 14.695 acres for $4,931,210, have cleared up to 100 acres per eight-hour shift with five of tbe big balls in action. A follow-up ingenious idea for clearing debris is described oo page 44. Editorial and Advertising Offices Munsey Building, Washington 4, D. C.
