are three pipes, in communication with the boiler # 5 

 and reservoir c; that is, two upper pipes, nine inches 

 broad, and two and a half deep, placed on an 

 edge, and running parallel to each other, and one 

 circular return pipe, which is about four inches in 

 diameter, and returns directly under the two flat 

 ones, and thus conducts the water from the reservoir 

 back into the boiler, close to the bottom of which 

 it enters. This boiler consists of a concave bottom 

 and steam-tight top ; its length is two feet two 

 inches by two feet two inches in width, and it is fixed 

 in a niche in the front of the end wall of the house, 

 and attended from the shed, wherein is placed the 

 furnace for the heathery. The advantage of having 

 the fire placed in the front, here, exists in the facility 

 of getting the smoke conveyed into the old flue e, that 

 runs along the back path of the house, and tends 

 considerably to keep up the temperature, inasmuch 

 as the heat that is conducted along it penetrates 

 through the tiles into the house, which, otherwise, 

 would be wasted by passing up the chimney. The 

 principal advantage, apparently, of having the two 

 flat pipes on an edge, in lieu of one of larger dimen- 

 sions,, consists in their exposing a greater surface of 

 heated metal to the house, whereby its temperature 

 is raised more expeditiously. 



These pipes and boiler, were erected by the 

 Messrs. Barwell and Co., of the Eagle Foundry, 

 Northampton, whose iron castings, and workman- 

 ship, have been acknowledged to be superior to 

 those of many other recent erections, and who are 

 now extensively employed in the manufacture of the
