Drainage
* * * "I use one and a half inch pipes for the upper end of drains
(_though I prefer two-inch_), one half being usually one and a half
and the other half two-inch. This for minor drains; the mains run
up to 9 or 10 inches, and even 18 inches in size, according to
their service.
"There is no doubt sufficient capacity in one-inch pipes for minor
drains; but, inasmuch as agricultural laborers are not mathematical
scholars, and are apt to lay the pipes without precise junctions,
it is best to have the pipes so large as to counteract that degree
of carelessness which cannot be prevented. The ordinary price of
pipes in this country will run thus: + meaning _above_,
and-_below_, the prices named:
1-1/2 inch 15s. +
2 " 20s. -
3 " 30s.
4 " 40s. +
5 " 50s. +
6 " 60s. +
"The price of cutting clays 4 feet deep, will vary from 1d. to
1-1/2d. per yard, according to density and mixture with stone; and
the price of cutting in mixed soils will vary from 1-1/2d. to 6d.,
according to the quantity of pick-work and rock, and with respect,
also, to the price of agricultural labor. (See my tabular table of
cost in Land Drainage and Drainage Systems.)
"I should have thought it would have been quite worth the while of
the American Government to have had a farm of about 500 acres,
drained by English hands, under an experienced engineer, as a
practical sample of English work, for the study of American
agriculturists, with every drain laid down on a plan, with the
sizes of the pipes, and all details of soil, and prices of labor
and material, set forth.
"I am, dear Sir,
"Yours very faithfully,

CHAPTER IX.
THE COST OF TILES--TILE MACHINES.
Prices far too high; Albany Prices.--Length of Tiles.--Cost in
Suffolk Co., England.--Waller's Machine.--Williams' Machine.--Cost
of Tiles compared with Bricks.--Mr. Denton's Estimate of
Cost.--Other Estimates.--Two-inch Tiles can be Made as Cheaply as
Bricks.--Process of Rolling Tiles.--Tile Machines.--Descriptions of
Daines'.--Pratt & Bro.'s.
The prices at which tiles are sold is only, as the lawyers say, _prima
facie_ evidence of their cost. It seems to us, that the prices at which
tiles have thus far been sold in this country, are very far above those
at which they may be profitably manufactured, when the business is well
understood, and pursued upon a scale large enough to justify the use of
the best machinery. The following is a copy of the published prices of
tiles at the Albany Tile Works, and the same prices prevail throughout
New England, so far as known:
