and the last-mentioned size will hold the same number of the inch 
pipes inside of them, making therefore 24,800 of both sizes. In 
good weather this kiln can be filled, burnt, and discharjred once 
every fortnight; and 15 kilns may be obtained in a good season, 
producing — 
705,000 1 inch pipe tiles ;

and so on in proportion for other other sizes. 
N.B. — If a kiln of larger diameter be built, there must be 
more fireholes, and additional shed room.

6th Point. Cost of tiles when ready for sale. 
As this must necessarily vary with the cost of fuel, rate of wages, 
easy or difficult clay for working, or other local peculiarities, I can 
only give the cost of tiles as I have ascertained it here according 
to our charges for fuel, wages, &,c. iS:c. Our clay is strong, and 
has a mixture of stones in it, but the machine is adapted for work- 
ing any clay when properly prepared. 
It requires 2 tons 5 cwt. of good coals to burn the above kiln 
full of tiles. Coals are charged here at 28s. per ton, or 1000 
brush faggots will effect the same purpose, and cost the same 
money ; of course some clays require more burning than others ; 
the stronger the clay the less fuel required. 
The cost of making, the sale prices, and number of each sort 
that a waggon with 4 horses will carry, are as follows: —
