Now, a large area can only be secured by making drains deep and close together; and in the case supposed above, it appears to nie tliat 3 feet in depth, with 15 feel asunder, will not give a greater area than is requisite for drawing water out of such ground. When, on the other hand, the subsoil is free, and discharges water as freely, so large an area is not required to dry the subsoil, and drains of less depth and at greater distance will answer the same purpose as in the other case, such as 30 inches in depth and 30 feet asunder. You must endeavor to make the depths and distances of the small drains suit the nature of the subsoil, for it is impossible for me to lay down here any absolute rule in a matter which admits of such diver- sity of character. (816.) Small drains, as well as mains and sub-mains, should be com- pletely cast out, gauged, and examined for the fall, before being attempted to be filled up; and the materials for doing so should be laid down beside them, as well as in the case of mains. The tiles for small drains are smaller than for mains and sub-mains, being 3 inches wide and 4 inches high, inside measurement, which may be considered a large tile in places where those of 2^ inches wide by 3^ inches high are used ; but so small ones are not made everywhere. There is this consideration in regard to the size of tiles which should be kept in view, that a substantial tile will have the chance of lasting much longer than a slight one, and the proba- bility is, that the larger ones are the more substantial, which, however, may not actually be the case, but it is proper to examine whether they are neavy and firm, before you purchase your tiles.
