be used? As this is only a temporary 

 house and I can get these two boilers 

 cheap, 1 should like to use them if 

 possible. C. H. 



If each of the boilers has a grate 

 fifteen inches in diameter, they would 

 probably answer, but to keep up a 

 steady fire in so small a boiler will 

 require extremely careful attention, 

 and as the eggplant is a crop which 

 will be ruined if the temperature is not 

 fairly uniform, I advise the use of 

 one boiler with a grate twenty inches 

 in diameter. For flow pipes, carry one 

 2-inch pipe under the ridge and one on 

 each plate. Connect each flow pipe 

 with four lVl>-inch returns. In case 

 the wall on the west side is too low for 

 this method of piping, run one 2V2-inch 

 flow under the ridge and connect it 

 with fourteen I^^-inch returns distrib- 

 uted as evenly as possible. 



OHIO VEQETABLE HOUSES. 



I am erecting two vegetable houses, 

 each 20x100, with a wall between them, 

 so as to be able to maintain different 

 temperatures. I want to know how many 

 2-inch pipes will be needed in each 

 house, to heat one to 70 degrees and the 

 other to 60 degrees. The side walls are 

 four feet high and consist of two feet 

 of cement and two feet of glass. Solid 

 beds will be used. I shall run 2l^-inch 

 flows overhead, dropping to the returns 

 at the farther end of the houses, and 

 I am not much in doubt about any of 

 the details except the amount of piping 

 to be used in the returns. My esti- 

 mate includes eight 2-inch returns for 

 each house; is that enough? Will a 

 fall of six inches from the farther end 

 to the boiler be suflScient? The houses 

 are in central Ohio. They run east and 

 west and are well protected at the west 

 end. I am using a Boynton 12-section 

 boiler, rated for 5,500 square feet of ra- 

 diation; is that enough? J. L. S. 



For a vegetable house 20^100 feet, 

 with two feet of glass in one wall, to be 

 heated to 60 degrees , with hot water, 

 use three 2 1^ -inch flow pipes and ten 

 2-inch returns. While eight returns 

 would answer in this house, it would 

 require heavy firing in severe weather 

 to maintain a temperature of 60 de- 

 grees, and it will be more economical 

 of fuel if nine or ten returns are used. 

 For 70 degrees, in the other house, three 

 additional returns will be needed. 



If the fall is carefully graded, six 

 inches will be sufficient. A boiler rated 

 for 2,000 to 2,400 square feet of radia- 

 tion would be large enough to heat the 

 two houses. 



A SMALL PENNSYLVANIA HOUSE. 



Please inform me of the most certain 

 method of heating my small new green- 

 house. I wish to maintain a tempera- 

 ture of 60 degrees, with hot water heat. 

 The house is 161/2x22. The walls are 

 constructed of concrete to a height of 

 three feet, with twenty-six inches of 

 glass fri)m the concrete wall to the 

 plate. There are two glass gables, eight 

 feet six inches high from the concrete 

 wall to the ridge. State what size and 

 number of radiating pipes will be 

 needed. My steam fitter tried to per- 

 suade me to use a wall radiator under 

 each of the outside benches. Would 

 that be practical? P. K.
