Every flue has its own separate clean- 

 out door— you can clean any flue at any 

 time with any fire. 



Do not warp out of shape like big 

 doors, and affect the draft.

tell definitely how much radiation a given 

 heater can handle. However, as the area 

 of the grate is only four and one-half 

 square feet, it cannot be rated higher 

 than 1,500 square feet of radiating sur- 

 face, and it is probable that 1,250 feet 

 would be enough for it, while the radia- 

 tion now in the houses is 2,000 square 

 feet. Under these conditions economical 

 results should not be expected. 



An even greater discrepancy is notice- 

 able when the amount of radiation in the 

 different houses is compared. The carna- 

 tion house has fifty per cent more radia- 

 tion than the rose house, although it is 

 only two feet wider, and this difference 

 in width is more than balanced by the 

 higher temperature required for roses. 



At the most only eight runs are required 

 in the carnation house, and seven would 

 answer for chrysanthemums, while to 

 carry the rose house at 60 degrees at 

 least ten runs of 2-inch pipe should be 

 used. If the top of the heater is well 

 below the level of the returns, fairly good 

 results can be secured by using three of 

 the 2-inch pipes as flows in each house, 

 and the others as returns, but it will be 

 even more satisfactory if two 2 ^^ -inch 

 pipes are used as flows and flve, six and 

 eight 2-inch returns are used respectively 

 in the chrysanthemum, carnation and rose 

 houses. 



SIZE OF MAIN FLOW. 



How large a main flow will be required 

 to furnish steam to 100,000 square feet 

 of glass, the steam to be carried 300 feet 

 from the boilers, with a pressure of 

 twenty-five pounds? I am located in In- 

 diana. A. R. 



If the pipe is well insulated it need 

 aot be larger than 5-inch, although bet- 

 ter results can be secured if a pressure 

 i-f at least forty pounds is carried in the 

 main flow pipe. 



The Eeview can supply any horticul- 

 tural books at publishers' prices.
