The slush scraper,as shown in Figure 106, may be used to advantage. Achain, to or more feet long, is necessarv tliat the team Figure 101. The depth of the ditch having been recorded onthe stake at each station, or only in tlie notes, measurement canbe made from the station to a given point above the proposedbottom for the drain, say 7 feet, and a small steel wire, broomwire, can be stretched between the two stations parallel to thebottom of the ditch. It is then a simple matter to measure downwith an L-shaped measure set to determine the proper depth tograde tlie bottom of the ditch with a tile Figure 102. Quiet water in a sag in a drain tile allows sedi-mc-ni, to settle there and clog the drain. DRAINAGE 211 may be backed up near to the ditch. Where theground is solid, the eveners may be carried on the frontwheels of a wagon, or better still, by means of the hindwheels of the wagon, supplied with a tongue. The hindwheels being larger can be backed up more easily. Oneman can some-times do thiswork, but asecond man isusually neces-sary to drive theteam, at leastuntil it is taughtto turn and backat command.
