the residence. Unless the highest point 

 in the roof of the residence is more than 

 twenty-five feet from the ground, it will 

 not seriously shade the greenhouse even 

 during the shortest days in winter. 



We are not able to discover the 

 amount of glass, if any, in the walls of 

 the greenhouse, but if the house has well 

 built • walls of wood or concrete, we 

 would use a boiler rated for 600 square 

 reet of radiation if it is to be placed 

 in the cellar of the residence, while it 

 will only require 400 square feet of 

 radiation if it is to bo placed at the 

 north end of the greonliouse. Either 

 location would give good results. 



We would prefer to drop the boiler 

 one foot if it is placed in the collar, 

 as it Avould thus be possible to carry the 

 flow pipe underground directly to the 

 greenhouse, but' if this is not feasible 

 the flow pipe may be dropped so as to 

 carry it underground. The expansion 

 tank should be connected with the high- 

 est point of the flow pipe above the 

 boiler and should be located at some 

 point in the residence, so that the top 

 of the tank will be just below the level 

 of the ridge of the greenhouse. 



After running the flow pipe from the 

 residence to the greenhouse, carry it up 

 to a height of eight feet. At the high- 

 est point run up a half-inch pipe, as an 

 air vent, to the level of the ridge. The 

 main flow and return pipes should be 

 3-inch. After taking off the air vent, 

 run a 2 M; -inch pipe to each side wall 

 plate and extend these pipes with a 

 slight fall to the north end of the green- 

 house and there connect each of these 

 flow pipes with a coil of five 2-inch re- 

 turns on the side walls or under the side 

 benches. If run underground, the main 

 flow and return pipes should be insu- 

 lated with asbestos wrappings aiid 

 placed in 8-inch sewer pipe, or both (of 

 the mains mav bo in one concrete con- 

 duit. 



If the boiler is at the north end of 

 the greenhouse or if the boiler in the 

 cellar of the residence can be lowered 

 80 that the main flow can be carried 

 directly on an up-grade of one inch in 

 twetity feet, the piping in the green- 

 house will be as described except that 

 the expansion tank should be located 

 directly under the ridge of the green- 

 house and connected with the highest 

 point of the system by means of a 

 %-inch pipe. 



THE SEEDLINGS NEED POTTING. 



Will you tell us, if possible, what is 

 the matter with the enclosed asparagus 

 plants, taken from the seed bed? Is 

 their condition due to red spider? If so, 

 please give us some information on how 

 to prevent further trouble. 



W. P. N. C— Fla. 



I do not find any trace of red spider 

 on the young asparagus seedlings and 

 I think the trouble is duo to allowing 

 them to remain too long in the sood 

 bed. The young plants should be potted 

 up promptly and treated liberally as re- 

 gards moisture, so as to keep them con- 

 tinually in active growth. M. P.
