It is Mr. Parkersopinion that laborers on this class of excavation shouldwork in gangs of 30 men each, subdivided into crews of15, one crew for every cart. Third. Each man is required to count his each 50 seconds he must load 5 shovelfuls, no less, nomore. The claim is made that the counting has a beneficialand stimulating LO o CO 6 PILE DRIVING 107 PILE DRIVING Wooden Piles are generally of spruce, pine or does not possess sufficient elasticity. If they areto be used as columnar piles it is necessary that they beabsolutely straight; if as bearing piles they should be fairlystraight; and in either case of sound timber. The minimumdiameter of the butts is 12 inches and of the tips 8 should be sharpened to a point before driving andsometimes it is necessary to protect the point by an ironshoe. The butts are cut off square and adzed so that awrought-iron band may be slipped on to protect the pilein driving. Piles should be driven until the movement isnot more than one-half an inch under a 1500-pound ramfalling 15 feet on the last blow. Piles are used in park engineering in constructing founda-tions for walls, abutments, spillways, etc. When used infoundations it is better to cap them with concrete than toattempt to construct a timber grillage.
