east ends of houses Nos. 2, 3 and 4; tem- 

 perature, 70 degrees. The boiler will be 

 in the north end of this shed. L. C. B. 



The house 13x25 should have a ly^- 

 inch or 2-inch flow and fifteen 1-inch re- 

 turns; the houses 14x84 should each be 

 piped with a 2-inch main flow pipe and 

 fourteen 1-inch returns, while the houses 

 24x84 should e^ch be supplied with a 

 2Vj-inch main flow pipe and seventeen 

 1-inch returns. The shed can be heated 

 by carrying a main supply from the 

 boiler, beginning with 4-inch and reduc- 

 ing to 2% -inch between the last two 

 houses, and in addition eight or nine 1- 

 inch radiating pipes. To carry this 

 amount of radiation, you should have a 

 boiler with at least 400 square feet of 

 heating surface, which would be approxi- 

 mately equal to a horizontal tubular 

 boiler rated at thirty horse-power.

AN ADDITION FOR CARNATIONS. 



We intend to build a new greenhouse 

 alongside the old ones. The new ones are 

 twenty feet wide, running east and west. 

 The side walls are five feet high and the 

 ridge is ten feet high. I should like to 

 take the south wall out and connect them, 

 and make the new one twenty-four feet 

 wide. Now, I should like to know 

 whether the house would not be too flat 

 if we make it only ten feet high, or 

 whether it would shade the other houses 

 if we make it higher. 



What would be the best way to ar- 

 range the benches? Would it be enough 

 to support each side of the roof with one 

 row of %-inch pipes, having the stand- 

 ing pipes ten feet apart? How many 

 2 14 -inch return pipes would we need to 

 heat the house with a hot water system, 

 having a 5-inch main pipe above the 

 benches? The house is for carnations. 

 The temperature in this part of Wiscon- 

 sin goes down sometimes to 20 or 30 

 degrees below zero. M. G. 



The flat roof you propose will not be so 

 satisfactory as one considerably steeper, 

 as it will reflect more light than one that 

 receives the sun's rays more nearly at 

 right angles when low in the south dur- 

 ing winter. The situation is, however, a 

 serious one, as it is not desirable to build 

 the house high enough to shade the pres- 

 ent structure. The flat roof will be the 

 lesser of the two evils, I judge, but it 

 will be necessary for you to use pipe not 

 smaller than 1^4 -inch for purlins, and 

 to use supports every eight feet. I can- 

 not answer the heating question, because 

 the length of the house is not stated.

CEMENT FOR FOUNDATION. 



How should I mix the substance for a 

 concrete foundation about 14x22, eight- 

 een inches wide and twelve inches high? 

 How much cement would I need for the 

 above-mentioned foundation and when is 

 the best time to build ? A. C. L. 



The proportion of cement should be 

 one to seven of gravel or cinders. The 

 amount of cement required will be in the 

 vicinity of seventy bags, to complete 

 the foundation. Ribes.
