wner has the right to follow the rules of
good husbandry in the drainage of his land, so far as the water of
pressure is concerned, without responsibility for remote consequences to
adjacent owners, to the owners of distant wells or springs that may be
affected, or to mill-owners.
In considering the effect of drainage on streams and rivers, it appears
that the results of such operations, so far as they can be appreciated,
are, to lessen the value of water powers, by increasing the flow of
water in times of freshets, and lessening it in times of drought. It is
supposed in this country, that clearing the land of timber has sensibly
affected the value of "mill privileges," by increasing evaporation, and
diminishing the streams. No mill-owner has been hardy enough to contend
that a land-owner may not legally cut down his own timber, whatever the
effect on the streams. So, we trust, no court will ever be found, which
will restrict the land-owner in the highest culture of his soil, because
his drainage may affect the capacity of a mill-stream to turn the
water-wheels.
To return from our digression. It is necessary, in order to a correct
apprehension of the work which our drains have to perform, to form a
correct opinion as to how much of the surplus moisture in our field is
due to each of the three causes to which we have referred--to wit,
rain-water, which falls upon it; springs, which burst up from below; and
water of pressure, stagnant in, or slowly percolating through it. The
rain-tables will give us information as to the first; but as to the
others, we must form our opinion from the structure of the earth around
us, and observation upon the field itself, by its natural phenomena and
by opening test-holes and experimental ditches. Having gained accurate
knowledge of the sources of moisture, we may then be able to form a
correct opinion whether our land requires drainage, and of the aid which
Nature requires to carry off the surplus water.
WHAT LANDS REQUIRE DRAINAGE?
The more one studies the subject of drainage, the less inclined will he
be to deal in general statements. "Do you think it is profitable to
underdrain land?" is a question a thousand times asked, and yet is a
question that admits of no direct general answer. Is it profitable to
fence land? is it profitable to plow land? are questions of much the
same character. The answers to them all depend upon circumstances.
There is land that may be profitably d
