Greenhouse Heating. 



If "Old Subscriber," who uses a Ma- 

 honey boiler, will send his full name and 

 addi'ess an effort will be made to answer 

 his inquiry. Anonymous questions never 

 can be answered. 



INSTALLING NEW PIPING. 



I have a greenhouse 22x5U, full-span, 

 running north and south, four feet high 

 to the eaves and ten feet to the apex. 

 The sides are of stone, pierced to pro- 

 vide for ventilators, 1x3 feet, three on 

 each side. The south end is all glass; 

 the north end is joined to the potting 

 shed. The greenhouse is an old-fash- 

 ioned one and is heated with the old 

 system of 4-inch pipes under the 

 benches at the sides. The benches ex- 

 tend the whole length at the sides and 

 half the distance in the center. 



I wish to install new piping, to main- 

 tain a temperature of 50 degrees when 

 the outside temperature is 5 degrees 

 below zero. I am located in southern 

 Rhode Island. »I have a hot water 

 boiler, nearly new. I can not state its 

 capacity, but am sure it is adequate. I 

 am planning to use two 3-inch flows, 

 hanging from the purlins over the 

 paths, and each connected to twelve 2- 

 inch returns, six down the front of 

 the side bench and six down the back, 

 three above and three below the sur- 

 face of the bench. Or should both sets 

 be an equal height from the floor I 

 "Would that piping be sufficient to main- 

 tain the temperature desired? I ex- 

 pect to clear out the 4-inch pipes alto- 

 gether and to use the house for carna- 

 tions. S. W. S. 



The radiation suggested in the query 

 more than will be required, as the 

 acoired temperature can be obtained 

 by the use of two 2 1^ -inch flow pipes 

 and ten 2-inch returns. It is always ad- 

 visable to have the coils as nearly 

 at the same level as possible. The 

 flow pipes may be either on the purlins 

 or on the side walls, as preferred.

The Market. 

 The report on local conditions for 

 last week is anything but favorable. 

 The unseasonably hot weather brought 

 on an avalanche of stock of all descrip- 

 tions and it was simply impossible to 

 move it. One would expect that the 

 supply of roses, owing to replanting op- 

 erations, would be reduced considerably, 

 but that seems to cut no figure at this 

 time. The supply of carnations, which 



The New 



^^Detroif Return Trap 



The only successful modifications in Tilting Traps made 

 in years have been embodied in the " Detroit." Improve-
