Building a railroad; a handbook devoted to a new, speedy and economical method of performing every operation from grading right-of-way to ballasting and maintaining track . e stumps with from 15to 20 lbs. of powder to thestation of 100 ft., as com-pared with 35 to 40 lbs. bythe arm strong method. Removing a Slump J^e Stunip is then pulled out bodily by the machine by running a chain fromstump to center dipper tooth and hoisting thedipper. The grubbing and grading are both done at onesetting of machine, completing the grade as it goes. Boulders and stumps are not only removed fromwhere imbedded, but are conveyed by the machineout of the way, clear of the grade. The America?i de-posits stumps and boulders 30 feet on either side of thecenter grade line, thus clearing a 60-foot right-of-way,and with the pullback drum can remove such ma-terial to a greater distanceif desired, by use of snatchblock. This drum holds 725feet of 5 8 inch wire rope. The steam shovel failsin this performance for thethe following reasons: First—Fixed boom rad-ius. Second—Does not work %%in full circle. Third—Has no extradrum for doing special work.
