the flow under the ridge, if one flow is 

 sufficient, and the returns on the side 

 walls. We want to maintain 50 de- 

 grees at night, using 2-inch pipes for 

 the returns. The house is detached ex- 

 cept the one gable. Missouri climate.

Use a 3-inch flow under the ridge, if 

 only one is to be put in, or have a 2%- 

 inch flow pipe upon each wall. Nine 2- 

 inch pipes will answer for the returns, 

 using five on the south and the others 

 on the north wall. 



INSUFFICIENT PIPING. 



I am enclosing a diagram of our 

 houses, showing the heating plan in 

 such a way that I think you will un- 

 derstand it. We cannot heat satisfac- 

 torily even one house, the west one, 

 which is the only one we try to run 

 during really cold weather. The out- 

 side temperature in this part of Maine 

 occasionally runs from zero to 20 de- 

 grees below, rarely 28 degrees below. 

 Kindly suggest a practical way to pipe 

 so as to heat both houses to grow car- 

 nations or bedding plants. We grow 

 lettuce early, then tomatoes, cabbage, 

 cauliflower, celery, asters, stocks, etc., 

 and we also carry some geraniums and 

 ferns, trying to do everything for a 

 town of 3,000 people. 



I have thought that, if we should get 

 to running all winter, instead of start- 

 ing in February as we do now, and 

 should grow, say, carnations in one 

 house and vegetable plants in the other, 

 it might be practical to increase the 

 boiler capacity and run pipes into the

The sketch shows two houses, each 

 lGx40 feet, with wooden walls. The 

 piping consists of four 2-inch flow pipes 

 along the walls, each of which supplies 

 a 2-inch return. This would furnish a 

 little over 200 square feet of radiating 

 surface, while to maintain a tempera- 

 ture of 50 to 55 degrees at night, under

 Carry 40 or 50 pounds pressure

 would require approximately 300 square 

 feet. The method of piping, also, is 

 calculated to give a sluggish circula- 

 tion.
