DRAINAGE
The laterals should enter the branches and mains near the
top, so that the water will be drawn out rapidly. The tile should be
laid with close joints at the top, so that the water may enter more
freely from the sides than the top. No covering other than moist soil
is needed unless there is very fine sand, when paper over the joints
will serve a good purpose. After some moist soil from the sides of the
trench has been tramped upon the tile, the trench may be filled by use
of a breaking-plow or winged scraper.
