GRADING Staking Out the Work. Grade stakes are set at the in-tersections of the cross-section lines and at every changeof slope. The stakes are marked on the side with the propercut or fill measured from the top of stake or they are sodriven that their tops are to grade, in which case the tops. 1-1 CO 6 TOPSOIL STRIPPING 97 are marked with red water-proof crayon. Stakes set tograde are better than cut or fill stakes and should be usedwherever possible even though a slight hole may be may be driven alongside to indicate their and fill stakes should be marked in feet and inches andnot in feet and tenths. For heavy fills long poles aresometimes used with their tops at^the finished grade, thusdoing away with the labor of setting more stakes after thefirst have been covered up. Where the cut is considerable,the first cut stakes set will not remain during the excavationoperations unless left on little hillocks, and to do this isexpensive. Therefore after the first cut stakes have beenplowed up or otherwise removed, other stakes in the sameposition will be necessary. Topsoil Stripping. The first thing to be done is tostrip the entire tract of its topsoil, which may be from 6inches to a foot in depth. The soil is piled in lar
