The magazine or coal chamber holds suflScient fuel to keep fire 12 

 hours or longer without attention. Best for a small greenhouse.

Subscribers are inyited 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 Beview to malce a choice of ap- 

 Pfu-atus 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. 



STEAM HEAT IN SMAU. HOUSE. 



I have a greenhouse 14x37 and ten 

 and one-half feet high to the ridge. 

 The side walls are six and one-half 

 feet high and there are two feet of 

 glass in the east wall. The house runs 

 north and south and is protected on 

 the west side by another greenhouse. 

 How much steam radiation will be re- 

 quired to heat the house to 60 degrees 

 in zero weather? How many lineal feet 

 of 2-inch pipe will be needed to heat 

 the house? Which arrangement of the 

 returns is the more effective, on the 

 side walls or under the benches? How 

 many feet of steam radiation is repre- 

 sented by a shell boiler six feet in 

 length and three feet in diameter, con- 

 taining seventy 1%-inch flues, four feet 

 long, with return fire? The boiler is 

 bricked in. A. W. F. — Mich. 



A greenhouse like that described, 

 with two feet of exposed glass in one 

 dTSe wall, can be heated to 60 degrees 

 by using 125 square feet of steam ra- 

 diation. If 2-inch pipe is used for both 

 flows and returns, we would install one 

 flow and four returns, but we would 

 prefer to use six 1%-inch returns. We 

 recommend placing part of the returns 

 under the benches, if they are not 

 placed too near the bench bottoms and 

 if care is taken to avoid the drying out 

 of the soil. However, when there are 

 walks located along the walls, and espe- 

 cially if there is glass in the walls, we 

 would have about one-half of the re- 

 turns on the walls. 



For small greenhouses we prefer to 

 use hot water radiation, since it gives 

 a more regular temperature and re-

quires less care. In piping the house in 

 question for hot water, we would use 

 a 2-inch flow upon each plate and nine 

 1%-inch returns, placing the odd re- 

 turn on the east wall and dividing the 

 others so that there would be some re- 

 turns under each bench. 



The boiler described would be rated 

 at ten to twelve horsepower, according 

 to the size of the grate. There would 

 be something hke 180 square Tfeet of 

 fire surface in the boiler and this would 

 probably answer for 600 square feet 

 of steam radiation. 



GET YOUB COAL IN NOW. 



The worst car shortage since 1907 is 

 shown in the report of the American 

 Railway Association as of October 1. 

 On that date there was a net shortage 

 of 61,300 cars. The shortage had in- 

 creased 41,157 cars in a month. At the 

 same date last year the surplus was 

 78,331. 



These figures will give an idea of 

 what will happen when the movement

of cars is slowed up by severe cold and 

 heavy snows. It behooves every green- 

 house manager to see to it that he has 

 a supply of fuel sufficient to keep his 

 place from freezing up if he should 

 find his receipts of coal cut off for 

 weeks at a time. 



Most of the large growers bought 

 their coal months ago and it now is 

 only a matter of getting deliveries on 

 the contracts. The contract price was 

 .high this year, for Pocahontas usually 

 $1.35 at the mine against a former* 

 price of $1.25, $1.10, $1 or even 90 

 cents as one counts the years back, but
