Cross-Bar, showing REMOVABLE FINGERS, and 



correct air area, resulting in perfect combustion, 



more heat, less fuel, impossible to burn' out, 



a pleasure to operate.

 OWNERS: 



We have a special offer

fireenhouse Heating. 



John Marsh, of the Marsh Floral Co., 

 Bay City, Mich., wants to know if any 

 grower has a successful electric pump for 

 taking hot water from a condensing tank 

 and putting it back in the boiler. Write 

 to him direct or through The Review. 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



USE SEPARATE MAINS. 



Will you please tell us how many rows 

 of 114-inch hot water pipe we shall need 

 in a house 16x40? It runs east and west. 

 We have one house 27x40, and south of 

 this is the 16-foot house, which has 

 4-foot side walls, entirely or glass. The 

 boiler, which is at fhe east end, has a 

 fire grate 36x36 inches. We expect to 

 grow chrysanthemums in the fall and 

 geraniums' for the spring trade. We 

 should prefer to put the piping around 

 the wall, so we can grow chrysanthe- 

 mums on the ground. Will it be neces- 

 sary to have a new flow pipe from the 

 boiler, or will it be satisfactory to tap 

 the piping in the house 27x40, which has 

 a 3-inch flow pipe? The expansion tank 

 is at the west end. We want a tem- 

 perature of 00 degrees in zero weather. 

 W. H. G.— O. 



For the best results we would use 

 3-inch main flow and return pipes for 

 the house 16x40, and would prefer to 

 connect directly with the boiler. As we 



LOOK AT IT 



understand it, the house to be heated is 

 16x40, with four feet of glass in each 

 of the walls. This will require about 

 350 square feet of radiation if a tem- 

 perature of 60 degrees is to be main- 

 tained. The main flow pipe should be 

 carried to the end of the house and there 

 connected with two 2 ^^ -inch feed flow 

 pipes. These should be carried on the 

 wall plates or about three feet below 

 the ridge, and connected at the farther 

 end of the house with ten 2-inch or four- 

 teen 1^-inch returns, one-half the num- 

 ber being on each side wall. Unless the 

 east end of the house is considerably 

 exposed and the bench is built along 

 the end wall, it will answer if the coils 

 an on the side walls only.

give me some help with my heating 

 problems? I enclose a sketch of two 

 houses. House No. 1, the north house, 

 is already built and will be used for 

 propagating. The building of house 

 No. 2 is under consideration. House 

 No. 1 is 13x100 and eight feet high to 

 the ridge. The north rafters are six 

 feet long, the south ones ten feet. The 

 north wail is four and one-half feet high, 

 the south wall three feet high. There 

 is no glass in the side walls. How much 

 radiation should the boiler have for 

 house No. 1 only? How much radiation 

 should the boiler have for the two 

 houses, if I build house No. 2 of the 

 same dimensions as No. 1 and connect 

 the two houses by a boiler shed? I 

 shall use a hot water system. 



If I build house No. 2, how many 

 feet south of No. 1 should it be, so as
