boiler is below the level of the floor of 

 the houses, a 4-inch overhead flow pipe 

 will answer to supply the five 214-iiich 

 flow pipes in house B. The main return 

 should be of the same size. 



To heat the two houses by steam, a 

 boiler with the same size of grate will 

 be needed. This would be rated at about 

 twenty horsepower. 



In house A use one 2-inch flow pipe 

 under the ridge and ten 1^-inch returns. 

 About three should be upon each wall 

 and the others under the middle bench. 



For house B use three 2-inch flow 

 pipes, one on each plate and the other 

 along the sides of the beds, or on the 

 purlhi posts. A 3-inch main will answer 

 to carry the steam to house B, with a 

 2-inch pipe for the drip. 



ESTIMATINa BADIATION NEEDS. 



Is there a general rule by which on* 

 may calculate the amount of radiation 

 needed f I have understood that the 

 number of feet of radiation needed for 

 50 degrees in zero weather could be ob- 

 tained by dividing the total number of 

 square feet of exposed glass by three, 

 dividing the number of square feet in 

 side wiQls exclusive of glass by fifteen, 

 dividing the cubic contents by 300 and 

 adding together these three results. 



I have a house 25x70 feet, with a

 tains an even, con-

 throughout your grow-

 every drop of the

 is now allowed to clog 

 up your steam lines, 

 directly back to the 

 boiler wbile it is hot.

 better flowers, but you 

 also save a large per

Big representative concerns like the Minneapolis
