large enough to feed all your returns, 

 but, if you wish, keep two. Twelve 2-inch 

 returns should be ample for your house 

 on a carnation basis. The extra pipe 

 can do no harm, but you have more 

 money in piping than is necessary.

HOUSES ON SLOPING GROUND. 



I have a piece of ground sloping to 

 the south, and 340 feet long from north 

 to south, with a fall of about three per 

 cent. I want to build a 6-room cottage 

 100 feet north of the greenhouses, and 

 for this reason would like to place the 

 steam boiler north of the greenhouses 

 and plan to build future houses to the 

 south. 



Would it not be advisable to begin 

 building on the south side of the ground, 

 placing the boiler south? This would 

 leave the boiler 250 feet from the cot- 

 tage. Would this be too far to heat 

 economically, and wliat size of flow 

 should be used to make the connection? 

 For the greenhouse I plan to run the 

 flow overhead, returning under the 

 benches with 1-inch pipe. The house will 

 be 27x200, heated to 50 degrees where 

 the outside temperature drops to 10 and 

 >6 degrees below zero. How large 

 should the flow be? How many returns 

 will be necessary and what size of main 

 return should these connect with, at the 

 end of the house, to the boiler? How 

 low would the boiler have to be to make 

 a steam trap unnecessary? How large a 

 boiler will be required, in horse-power, 

 including enough for an additional green- 

 house, 27x200? I am located in Illinois. 



G. J. B. 



I do not think it would be safe to 

 undertake to heat a plant such as you 

 contemplate, allowing 800 squa/e feet of 

 radiation for the cottage, with a boiler 

 rated at less than thirty-five or forty 

 horse-power. The boiler should be placed 

 deep enough so that the returns in the 

 greenhouses will be at least two feet
