returns. This will be for the south 

 house, which has four feet of glass. 

 For the north house, with a wooden 

 wall, two less pipes will suffice. 



The flow pipes can either be upon 

 the walls or supported on posts or from 

 the roof. In the house with benches 

 part of the returns can be underneath, 

 but it wUl probably be better to have 

 all of the returns on the walls in the 

 9jther house. The highest part *of the 

 flow pipes should be near the boiler and 

 they should be given a slight fall to 

 the farther end of the house, where 

 they' should connect with the returns. 

 These should'^lbe in coils, which should 

 also have a slight fall and should con- 

 nect with the boiler through a return 

 main of the same size as the flow. The 

 expansion tank should connect with the 

 highest part of the system. When only 

 45 to 50 degrees are needed, it will be

necessary to cut oflf about one-half of 

 the returns by means of valves. 



A boiler rated at 2,800 to 3,000 square 

 feet of radiation will be about large 

 enough for the two houses, and one of 

 4,000 to 4,200 feet would provide for 



a third house. In case there is no like- 

 lihood that mol^ than three houses will 

 be built, one boiler could be made to 

 answer for all of them, but if there 

 are to be four houses there will be 

 several advantages in having two boil-
