In accordance with GreatWestern standard practice, the craneshave been subjected to, and have suc-cessfully passed, a test load of 25 percent, above the working load. Over the Tehachapi in Joseph pulled out of the yard at 11 p. eighteen loads and a caboose. Therewas a hard road ahead of 162 miles upand down, over three ranges of motin -tains.

Aheavy forged steel post and a ring oflive steel rollers carry the superstruc-ture, and the top of the post is fittedwith ball bearings. In the other crane the lifting, slewing,jib-derricking and self-propelling mo-tions are operated by two horizontalcylinders 9 x 14 ins., the traveling mo-tion being driven by a shaft passingthrough the center of the post operat-ing a horizontal shaft by means of aworm and worm wheel. The horizon-tal shaft drives two intermediate shaftswhich are geared to two travelingaxles. The crane turns upon a livering of steel rollers, running betweencast steel roller paths, the upper bed-plate also being of steel. The boileris of the vertical multitubular type,4 ft. 8 ins., diameter by 7 ft. 2 ins. high,working pressure 80 lbs. per squareinch, and the jib is constructed ofwrought steel. The fol
