t 



boiler that indicates the display of much ingenuity in 

 its contrivance, yet it has been found to answer very 

 well as often as it has been tried ; and its great sim- 

 plicity renders it peculiarly well adapted for the use 

 for which it is recommended. 



A perfect idea of this boiler may be formed from the 

 following figure, where it is represented without the 

 wooden curb to which it is fixed when it is set in brick- 

 work : 



Fig. 87. 



This boiler is 24 inches wide, 36 inches long, and 15 

 inches deep ; consequently, when it is filled to within 

 3 inches of its brim, or when the liquor in ,it stands at 

 the depth of 12 inches, it contains 10,364 cubic inches, 

 which make above 362 beer-gallons. 



It should be constructed of sheet iron tinned on the 

 inside ; and, when it is not in use, care should be taken 

 to wipe it out very dry with a dry cloth to prevent its 

 being injured by rust ; and, as often as it is put away 

 for any considerable time, it should be smeared over 

 with fresh butter or any other kind of animal fat un- 

 mixed with salt. 



The sheet iron will be sufficiently thick and strong 

 if the boiler when finished weigh 40 pounds ; and, as 

 the best sheet iron costs no more than about $\d. per 

 lb., the manufacturer ought not to charge more than 

 6d. per lb. for the boiler when finished, which, if it 

 weigh 40 Ibs., will amount to 2os.
