STATEMENT OF SHEDD AND EDSON.

BOSTON, February 1, 1859.

DEAR SIR:--The plan for a system of thorough drainage, a copy of
which we send you herewith, was executed for Mr. I. P. Rand, of
Roxbury.

An outfall was obtained, at the expense of considerable labor, by
deepening the Roxbury and Dorchester Brook for a distance of nearly
a quarter of a mile, about four hundred feet of which was through a
rocky bottom, which required some blasting. The fall thus obtained
was only about two inches in the whole distance.

The fall which can be obtained for the main drain is less than two
inches per hundred feet, but the lateral drains entering into the
main, will have a fall varying from two inches to a foot per
hundred.

The contour lines, or lines traced along the ground, intersecting
points on an equal level, are drawn on this plan, showing a fall of
four-tenths of a foot, each line being in every part four-tenths of
a foot lower than the line above it. Where the lines are near
together, the fall is greater, as a less horizontal distance is
passed over before reaching a point which is four-tenths lower than
the line above.

It will be seen by the plan, that the fall in the line occupied by
the main drain is very slight, while the side drains have a fall
much greater.

The lateral drains are run in the line of steepest descent, which
is, of course, at right angles to the general direction of the
contour lines.

The water from the entire system is collected, and escapes at one
outlet into the brook.

A peep hole is placed at the intersection of the sub-main drain
with the main, which commands about one-half the entire area--the
other, half is commanded by the outlet.

Two-inch tile will be laid in the lateral drains, and three, four,
and five-inch in the sub-main and main.

It is quite indispensable, to the success
