Permanency Desired








The expense of underdrainage demands care in every
detail of the work. The grade of the trenches should be carefully
tested. Every piece of tile should be examined. The outlet should be
guarded against displacement or entrance by animals. A good plan is to
lay the last few pieces of tile in a close-fitting wooden box, and to
protect the end with iron rods placed 2 inches apart.

If the drain is on a true grade, so that no silt will collect, there
need be no fear concerning its continued efficiency, provided water
does not run in it all the time. If it carries the water from springs
continuously, plant-roots may fill it, and tree roots are quite sure to
do so when opportunity offers. This is notably true in case of elms and
willows, but protection is afforded in such an instance by closing the
joints with cement.
