with a walk through the center of the 

 house, will be quite satisfactory, as will 

 the use of three feet of glass in the 

 south wall of the lettuce house, in wliich 

 the crop is evidently to be grown in the 

 ground or upon slightly raised beds. 



For the lettuce house use two 2 1^ -inch 

 flows and eight 2-inch returns, and in the 

 carnation house two flows and five re- 

 turns. 



A RANGE OF FOUR HOUSES. 



Wo are building four greenhouses, two 

 of them 16x100 and the other two 20x100, 

 and intend to heat them with hot water. 

 The houses run from northeast to south- 

 west. The southeast side is four and a 

 half feet high, with eighteen inches of 

 glass and the lower part cement. The 

 two 16-foot houses each measure nine 

 feet to the ridge. We have planned to 

 use a 3-inch flow on each side, running 

 . them on the side walls, giving them a rise 

 of twelve inches to the back end and con- 

 necting with five rows of 2-inch pipes, to 

 return on each side below the benches. 

 Would that be enough piping to keep the 

 temperature up to 70 degrees in the cold- 

 est nights, here in southeastern Pennsyl- 

 vania? 



The two 20-foot houses are eleven feet 

 to the ridge. In these houses we propose 

 to put six rows of 4-inch pipes, to keep 

 a temperature of 55 degrees. Is our plan 

 a good one? J. C. F. 



The use of two 3-inch flow pipes would 

 take care of the radiation required in the 

 16-foot houses, and five rows of 2-inch 

 pipes upon each side of the houses in 

 the return coils would keep the tempera- 

 ture up to 70 degrees in the coldest 

 weather in your state. 



In the 20-foot houses the use of six 

 4-inch pipes, as proposed, would maintain 

 55 degrees, except in the coldest weather, 

 and then it should not drop below 50 

 degrees. 



IN WESTERN NEW YORK. 



How many runs of 2-inch returns and 

 what size of main will I need to heat my 

 greenhouse to 60 degrees in zero weather, 

 with hot water heat? The house is 21x50, 

 fourteen feet to the ridge and six feet 

 to the gutters. Three feet of the sides 

 is glass and three feet double boarded, 

 with paper between. The house runs 

 north and south. The north end is pro- 

 tected by a workshed; the south end is 

 glass. I will use three raised benches and 

 one solid bed. A. M. D. 



For a house twenty-one feet wide and 

 with three feet of glass in each side 

 wall, it will be advisable to have three 

 2 1/4 -inch flow pipes and fourteen 2-inch 

 returns. One of the flows and four re- 

 turns could be carried on each wall. The 

 other flow can be under the ridge or on 

 the purlin, as preferred, and two of the 

 returns could be under each bench. 



BUFFALO. 



The Market 



Mild weather still prevails and as yet 

 there is no frost in the ground. Chrysan- 

 themums still reign supreme and are sell- 

 ing fine for Thanksgiving. The medium 

 grades are the most sought after and 

 stock will be none too plentiful when the 

 big rush comes. Koses have been scarce 

 the past week, as have been carnations. 

 Valley and orchids are exceedingly 

 scarce, and it was hardly possible to get 

 an orchid flower the early part of the

 Steam Trap 



THE Morehead is the Standard Trap in the Florists' field. 

 There are more Morehead Steam Traps installed in 

 greenhouses than of all other types of traps combined. To 

 be a Morehead user is to be a thoroughly sati[>fied user.
