for each linear foot, it will take four- 

 teen runs of this size of pipe in the 

 returns to make up the needed radiat- 

 ing surface. While the foregoing size 

 of pipe will give fairly good results 

 and might be used if one has it on 

 hand, it would be better to run two 

 2%-inch pipes on the plate, with nine 

 2-inch returns distributed upon the 

 walls and along the sides of the solid 

 bed. 



PAINT FOB STEAM PIPES. 



We wish to paint the steam pipes in 

 our greenhouses. Will you kindly in- 

 form us whether there is any paint or 

 preparation known that will not throw 

 off gases or vapors injurious to the 

 stock when the pipes are heated? 



W. S. 



The ordinary coal tar and cheap as- 

 phalt paints are quite unfit for use in 

 greenhouses, especially upon the heat- 

 ing pipes. The better grade of as- 

 phaltum paints can be used for this 

 purpose, but, as they give a glossy 

 surface, the efficiency of the radiat- 

 ing surface would be somewhat les- 

 sened. A comparatively cheap, safe 

 and durable paint can be made by 

 adding one part of linseed oil to two 

 or three parts of turpentine and put- 

 ting in enough lampblack to make a 

 moderately thick paint. 



POSITION OF HEATING PIPES. 



Should steam pipes, fastened to the 

 gutter posts, be placed up near the 

 gutter or down low, to get the best re- 

 sults? When two houses are connected, 

 is it advisable to place two coils on 

 the same row of posts, or would that 

 cause too much heat in one place? 



J. W. E. & C. 



Ordinarily it is best to have the 

 steam pipes fairly well up from the 

 ground, under the gutters. In a green- 

 house there is but little difference in 

 the distribution of the heat, and by 

 having the returns somewhat ele- 

 vated the condensed water more readily 

 makes its way back to the boiler. 



In connected houses there is no ob- 

 jection to having twice as many pipes 

 upon the middle gutter posts as in 

 the case of a single house. On the 

 other hand, however, if the houses 

 have raised benches it is often desira- 

 ble to place rather more of the pipes 

 under the benches than in single

 how the initial pressure flurtuates. By carrying 40 or 50 

 pounds pressure on the boiler and setting the valve to 

 carry 6 or 10 pounds on the line, you always have a
