means were used for facilitating and expediting the 

 labour. 



The sheet iron used in the construction of this oven, 

 which was of the very best quality, cost 34^. per 

 gross hundred of 112 Ibs., which is at the rate of $\d. 

 and 1*1 of a farthing per Ib. The quantity used, 

 6 Ibs. 2 oz., must therefore have cost is. io^d. and 

 Y^j part of a farthing. 



If now we allow two ounces for wastage, this will 

 bring the quantity necessary for constructing one of 

 these ovens to 6| Ibs., which quantity, at the rate above 

 mentioned, would cost something less than is. nd.\ 

 and if to this sum we add is. for the making, this will 

 bring the prime cost of the oven to 2s. i id. 



Let us allow 20 per cent for the profit of the manu- 

 facturer, and still the price of the oven to buyers will 

 be only $s. 6d* 



In order to ascertain the expense of setting one of 

 these ovens in brick-work, I caused that above described 

 to be put up in the middle of a wide chimney fire-place 

 in my house in Brompton Row; and the work was 

 executed with as much care and attention as was 

 necessary, in order to render it strong and durable. 

 In doing this 114 bricks were used, and something 

 less than 3 hods of mortar; and the bricklayer per- 

 formed the job in 3 hours and 10 minutes. 



Three bricks set edgewise formed the grate or bot- 

 tom of the fire-place ; the middle brick being placed 

 vertically, and those on each side of it inclining a little 



* The oven I have here described was made by Mr. Summers, ironmonger, 

 of New Bond Street, who, before I acquainted him with the above computa- 

 tions, offered to furnish these ovens in any quantities at 4*. a piece. This, for 

 the offer of a manufacturer, I thought not unreasonable.
