one with glass in the side wall, which 

 should have an additional return. Piped 

 in this way, there should be no diffi- 

 culty in keeping the water in the flow 

 pipes above 180 degrees and in the 

 returns above 140 degrees, with an open 

 tank system. 



To maintain a temperature of 48 de- 

 grees, with the thermometer registering 

 20 degrees above zero outside, would 

 require from 500 to 800 pounds of coal, 

 according to its quality, and with an 

 outside temperature of 10 degrees about 

 twenty per cent more would be needed. 



HEAT FOB COLDFBAMES. 



I wish to use hot water to heat some 

 coldframes, and as I suspect that rules 

 for greenhouse heating will ndt hold 

 good for frames, I seek advice. The 

 frames are of concrete and are 4x60 

 feet, inside measurement. The south 

 or low side is twelve inches, the high 

 side eighteen inches, above the ground 

 level. The sashes are 3x4% feet. I 

 thought of running a 2-inch flow on the 

 high side, six inches from the sashes 

 (this would cast no shade on the 

 ground), with a 3-inch drop to the far- 

 ther end, and then a drop down to 

 twelve inches below the surface of the 

 soil in the frames, branching into three 

 2-inch returns. Each frame would be 

 piped in the same way. Lettuce and 

 radishes will be the fall and winter 

 crops, and about April 1 the frames 

 will be bedded to sweet potatoes, for 

 slips or plants. The potatoes will re- 

 quire a soil temperature of 58 to 65 de- 

 grees. In this part of Kansas we have 

 many zero days during winter, but
