they
have rebuilt, the number of tile they weekly commit to the waste pile,
the percentage of good and poor tile in each kiln, and many other things
that your humble servant will probably never suspect until he attempts
to manufacture tile.
A similar statement may be made with reference to drainage mistakes. How
many dry weather drains do we hear mentioned in our conventions, or see
described in our newspapers. By such drains, I mean those which in
favorable seasons so operate as to permit the land to produce a heavy
crop--one worth publishing--while in wet years, merely a total loss
results. Cases of such drainage can be numbered by the score. How many
miles of drain tile have been taken up and relaid during the past year
because of some mistake in plan, size of tile, or execution of the work?
Much might be said of drainage mistakes in a general way, but it is
proposed in this paper to treat the subject in a specific and practical
manner. It may be encouraging to remember that it is only by comparing
success with mistakes that we make progress in any valuable science or
art. Great skill and success rest upon a foundation of corrected
mistakes.
MISTAKE NO. 1--LACK OF INFORMATION ON DRAINAGE.
We might more properly call this the cause of many mistakes. "Knowledge
is power," says the old adage, and we might add that knowledge in
drainage is success. This knowledge may be obtained in three ways:
First, from reliable books; second, by inquiring of others who have had
experience; third, by our own experience. The first is of prime
importance to the beginner, for in books are found statements of the
general principles and philosophy of drainage, together with the best
methods and practice known. The second is often unreliable, for the
reason that the error of one is often copied by another and becomes wide
spread before it is detected. The third, though valuable is costly, and
discouraging to the learner. Gleanings from all of these sources will,
perhaps, give the most complete satisfaction.
Tile drainage began to be practiced in my own neighborhood about seven
years ago. Those who were about to begin knew nothing about drainage,
except from hearsay knowledge that had crept into the community. Not a
single book upon the subject was consulted or even inquired for. Even
now they are as rare in farmers libraries as the classic poets. Farmer
A. wished to drain and consulted farmer B., who had put in some tile the
year
