The pile being now completed, and the fire burning briskly, the screens may be 
removed. It takes 8 days to build a kiln of 200000 bricks. At Lille it occupies 
20 to finish one of 600000, with a height of from 75 to 90 courses. 
As yet no mention has been made of the species of coal employed, but m reality 
much of the success of the operation depends upon a proper solution or this in- 
^ For the flues, and for the interstices of the bricks, a bituminous caking coal, 
swelling and giving much flame, is preferred : on the other hand, a dull coal, burn- 
ing without flame, is most suitable for the coatings between the bricks another 
sort of coal intermediate between the two, may, however, be used m both situations 
without prejudice. When the rich coal is used alone, care must be taken to leave 
greater space between the bricks, and not to lay fresh tiers until full ignition shall 
be established up to the second bricks, under the feet of the workmen. 1 he dull 
coaky coal is much less troublesome to use, merely requiring the mouths ot the 
flues to be reduced in size ; for too much air extinguishes this coal, instead ot m- 
C1 At Valenciennes, about 115 kilo grammas (4 maunds) of coal, are all °'™ d 
1,000 bricks, besides 60 faggots, and 7 or 8 cubic yards of logs, llie cost per 
1,000 bricks may be thus estimated.

The above, assumed as the highest rate of charges, so that, notwithstanding^!! 
the advantages of cheap labour, cheap fuel, and low ground rent which we enjoy 
here, our Indian ground-made and misshapen bricks, still cost fully as much as the 
best table-made bricks of Flanders or Valenciennes.
