On Temporary Tile-Kilns. 
199 
The result ol tliis experience of lour years shows not only the 
practical value of this cheap kiln, but Mr. Hatcher, who super- 
intends the brick and tile-yard at Benenden, where this kiln 
stands, expresses himself slronsjly in favour of this kiln, as always 
producing better and more evenly burnt pipes than either of his 
larjje and regularly built brick-kilns can do. 
It will also be a satisfaction to those interested in the progress 
of agricultural draining, to know that draining-pipes, of the 
various dimensions mentioned in my letter to Earl Spencer, con- 
tinue to be made and sold by Mr. Hatcher on his own account, 
at the same prices therein stated, except that in future he must 
charge, for '2|-inch pipes, at the rate of 285. per 1000. This 
necessity arises from their large size and weight requiring them 
to be placed on their ends for drying, instead of being hacked 
horizontally as other and smaller pipes; there is also greater 
difficulty in setting them in the kiln for burning. He makes 
now 3-inch pipes at 40^. per 1000, which are not mentioned in 
that letter. The reason for an increased price is obvious, as these 
pipes take double the quantity of clay required to make a '2i-inch 
pipe, which he sells at 20s. per lOOO. The cylinder of the 
machine requiring to be twice filled to the other's once — causing 
thereby double labour in their making, as well as in the previous 
process of digging and preparing the clay. With this trifling ex- 
ception, the whole of the process of tile-making by Hatcher's 
machine, and the prices of each sort of pipe, continue the same as 
described in that letter.

This temporary tile-kiln has always appeared to me a very va- 
luable invention for those landowners who have drainage to execute 
on a small scale at a distance from a cheap tile-burner, or in 
the neighbourhood of a dear one, whom the mere preparation for 
raising a temporary kiln may induce to lower his prices. Such 
at least has been the result of my own experience, as without 
Mr. Hodges' paper on Temporary Kilns I should not have been 
able to buy inch pipes at 10s. per 1000; others, therefore, I 
should hope may find the power of burning their own tiles a de- 
fence against exorbitant charges. Ph. Pusey,
