68 CONSTRUCTION. 



house such as described, namely, twelve by one 

 hundred feet and seven feet to ridge, the boiler 

 would cost seventy five dollars. For each addi- 

 tional house of the same length joined to the next 

 without partition walls, an additional fifty dollars 

 should be added for boiler capacity. To heat a 

 house one hundred feet long and twenty-four feet 

 wide, such as described as the second type, would 

 require a boiler costing one hundred and twenty- 

 five dollars. For each additional house separated 

 from the other by an alley of eight feet, it would 

 require seventy-five dollars additional for boiler 

 capacity. When the amount of pipe to heat 

 exceeds twenty-five hundred square feet it is best 

 to have more than one boiler in fact it is a 

 question whether it is not best in all cases to have 

 boilers so arranged that there is a reserve on hand 

 for emergencies, which may arise at any time. It 

 is also a question as to whether it would not pay to 

 have a night fireman in all cases where the number 

 of plants exceeds ten thousand. 



This brings us to a consideration of the total 

 cost of the types of houses described. Taking one 

 hundred feet as the length, a house twelve feet 

 wide and seven feet to the ridge, with a twenty 

 inch opening on sides, would cost as follows: 



40 posts for side walls, 4x4 inches, 6 or 7 feet 



long, at 35 cents each $14 oo 



205 lineal feet s-piece gutter, 6 inches in clear, at 



$16.20 per ioo feet 33 21
