useless. This is an
extravagant waste of timber, except in the new districts where it is of
no value.
Mr. J. F. Anderson, of Windham, Maine, has adopted a mode of draining
with poles, which, in regions where wood is cheap and tiles are dear,
may be adopted with advantage.
Two poles, of from 3 to 6 inches diameter, are laid at the bottom of the
ditch, with a water-way of half their diameter between them. Upon these,
a third pole is laid, thus forming a duct of the desired dimensions.
The security of this drain will depend upon the care with which it is
protected by a covering of turf and the like, to prevent the admission
of earth, and its permanency will depend much upon its being placed low
enough to be constantly wet, as such materials are short-lived when
frequently wet and dried, and nearly imperishable if constantly wet. It
is unnecessary to place brush or stones over such drains to make them
draw, as it is called. The water will find admission fast enough to
destroy the work, unless great care is used.

In Ireland, and in some parts of England and Scotland, peat-tiles are
sometimes used in draining bogs. They are cheap and very durable in such
localities, but, probably, will not be used in this country. They are
formed somewhat like pipes, of two pieces of peat. Two halves are formed
with a peculiar tool, with a half circle in each. When well dried, they
are placed together, thus making a round opening.

In draining, the object being merely to form a durable opening in the
soil, at suitable depth, which will receive and conduct away the water
which filters through the soil, it is obvious that a thousand expedients
may be resorted to, to suit the peculiar circumstances of persons. In
general, the danger to be apprehended is from obstruction of the
water-way. Nothing, except a tight tube of metal or wood, will be likely
to prevent the admission of water.
Economy and durability are, perhaps, the main considerations. Tiles, at
fair prices, combine these qualities better than anything else. Stones,
however, are both cheap and durable, so far as the material is
concerned; but the durability of the material, and the durability of the
drains, are quite different matters.
