Makin(j and burning Draining Tiles.

the following passage : — "The expense (of thorough-draining) is 
estimated from 3/. to 12/. per acre, according to the frequency of 
their application." The price in my own neighbourhood and in 
the Isle of Wight was then 60*. per 1000 for tiles, and 30s. for 
soles, being 90a-. for every 1000 feet of materials. 
In 1841, we discovered that Mr. Beart in Huntingdonshire 
was selling tiles of about the same size for '22s., and the soles for 
about lO.v., being 32^. for every 1000 feet of materials. 
In 1843 we found that pipes of various shapes were sold in 
Suffolk and Kent at 20s. per 1000, being 'lOs. for every 1000 feet 
of materials. 
I was thus enabled in iMay, 1843, to give the following reduced 
estimate for draining an acre of land : —

Our engineer, Mr. Parkes, has since examined the subject of 
pipe-drainage most minutely. He has proved that in theory an 
inch-pipe can discharge the heaviest rains from the land, and he 
has gone far to shew their efficacy in practice. Mr. Parkes, in his 
Report on the Implements shown at Southampton, announces 
that such pipes are actually now selling in the Isle of Wight for 
12*. per 1000. I may, therefore, after so short an interval again 
have the pleasure of laying before the Society further reduced 
estimates of the price of drainage. The most convenient measure 
is, 1 think, the furlong, because that is the old dimension in length 
of an acre, the width being 66 feet ; and if the cost of one drain 
for that width be known, it is easy of course to calculate for nearer 
distances. A furlong, too, is equal to 40 poles, a common length 
in calculation for the digging of drains.
