Aside from this, the dip-per fills better if it is allowed to cut and fill grad-ually in a graceful, even pass, that lets it just clearthe slope of the cut, or material, nicely when it is desired, in widening a cut, the American canbe set down on standard gauge passing track or on itsportable track sections, which it transfers itself. Imay be either headed into the face of a cut which isat right angles to the track, or take material from cutwhose face is parallel to track, and load into material 58 Building a Railroad. mv ✌️tm:*i*sf Doun On Slandaid Gauge Track cars or onto flat carson the main method has beenfully explained underMaking Cuts andStraight Steam ShovelWork. If a fill is required andthe material can be bor-rowed at the side with-out interfering with future requirements for moreside tracks, observe the following method: Set the American down on the side of and atproper distance from the main track, and after borrow-ing the material, dump it on the new grade next tothe main track. As fully explained under Making Fills, theAmerican will dig enough material from one sideto make the following fill: Depth of fill, 5 ft. 6 of top, 14 , 1 to 1. The American here excels the steam shovel,because it can be taken any place, up or down, overdry or wet places, and the steam shovel must behandled
