Greenhouse Heating. 



The big blizzard that swept over the 

 country February 21 again disorganized 

 transportation and coal has come forward 

 slowly in the last week. With a suspen- 

 sion of mining operations March 31 al- 

 most certain, it behooves every grower 

 to put himself on the safe side in the 

 next three weeks. 



CEMENT WASH FOR PIPES. 



Would it be all right to paint the 

 heating pipes with a thin coat of lime 

 and cement? M. B. 



While there would be no particular 

 objection to painting the heating pipes 

 with cement or other similar washes, it 

 would tend to rub off in time. A more 

 durable wash can be made of lamp- 

 black mixed with equal parts of linseed 

 oil and turpentine. If the cement and 

 lime wash is used, it should be made 

 quite thin, as otherwise it wili be 

 likely to scale off and it will also im- 

 pede the radiation of heat. 



QUANTITY OF FUEL. 



In reply to the inquiry of L. M. M. 

 in The Review of January 25, page 84, 

 concerning the quantity of fuel per 

 1,000 square feet of glass, I will say 

 that in St. Louis we are using about 

 1,300 bushels of screenings and 300 

 bushels of lump coal of mixed grades 

 to heat 6,000 square feet of glass to 

 60 degrees. This equals sixty-four tons, 

 or ten and two-thirds tons per 1.000 

 feet of glass. 



We are using an internally ifired 

 tubular boiler with hot water under 

 pressure and like that type of boiler 

 for screenings, as it has relatively large 

 heating power in the flues, which are 

 cleaned every day, this being an im- 

 portant matter. 



With 10 degrees above zero and a 

 high broadside wind, it required twenty- 

 two bushels in twenty-four hours to 

 hold the temperature at 52 degrees, 

 which was as severe as any weather we 

 had, but we hold the temperature gener- 

 ally at 60 degrees. E. S. 



THREE DETACHED HOUSES. 



Please let me know the best way to 

 pipe my greenhouses. House No. 1, 

 which runs north and south, is 29x120, 

 sixteen feet to the ridge and six feet 

 to the eaves, with three feet of glass 

 in the sides. In this house, which is to 

 be used for carnations, I want a tem- 

 perature of 50 degrees in zero weather. 

 The boiler shed is at the north end of 

 house No. 1. House No. 2 runs west 

 from the north end of No. 1, but is 

 separated from No. 1 and from the boiler 

 shed by a passageway. This house is 

 16x100; it is eight feet to the ridge and 

 has 4-fpot walls. It is partitioned, mak- 

 ing two'rooms. The east room, the one 

 next to the boiler, is forty feet long; 

 the other room is sixty feet long. In
