inch flows and twelve 2-inch returns; 

 ■for houses 20x100, three flows and nine 

 returns; for house 20x50, two flows and 

 nine returns; for house 10x50, one flow 

 and five returns. 



If there is glass in the side walls, use 

 an additional return for each thirty 

 inches of glass. 



Wi:en only one flow pipe is used, it 

 should be under the ridge, as should the 

 third flow pipe in the wider houses. 

 Place the other flow pipes upon the 

 plates, in all cases giving them a slight 

 fall. 



We are not informed regarding the 

 p.i}mbej of benches in the different 

 houses. As a rule, we think it well to 

 run two or three returns under each of 

 the middle benches, with the others on 

 the side walls or under the side benches, 

 but we should have a majority of the 

 returns on or near the side wall, espe- 

 cially if these walls contain exposed 

 glass. 



HEATING HOUSE AND LEAN-TO. 



Please give me information concern- 

 ing the piping of a greenhouse and 

 lean-to. The house is 18x70 feet and 

 six feet high; the lean-to is 10x60 feet. 

 The heating will be by hot water, using 

 a HoUiday boiler with a grate 20x40 

 inches. The temperature required is 50 

 degrees in zero weather. I have 1%- 

 inch pipe which I should like to use for 

 returns. F. G. E. — Wash, 



If there is no glass in the exposed 

 walls of these greenhouses, we should 

 use for the wide house two 2^-inch flow 

 pipes and seven returns. In the lean-to 

 one flow and five returns will be suffi- 

 cient. If there is, exposed glass in the 

 walls, use a"n additional return for every 

 twenty-four inches of glass. 



We have had no experience with the 

 boiler mentioned, but judging from the 

 size of the grate it should have capacity 

 for heating fifty to 100 per cent more 

 radiation than will be required for these 

 houses, in the comparatively mild cli- 

 mate of southern Washington. 



PIPING A SMALL HOUSE. 



I am erecting a small greenhouse and 

 should like to know the best way to pipe 

 it and the size of boiler needed for hot 

 water heat. I am thinking of purchas- 

 ing a boiler manufactured by Giblin & 

 Co. It will be one of their No. 20 series 

 of standard hot water boilers and the 

 size will be according to the radiation 

 needed. 



The greenhouse will be 20x50, run- 

 ning north and south, with walls five 

 feet high. The west wall will be of 

 wood and the east wall will have two 

 feet of glass and three feet of wood. 

 The north end will be of wood and will 

 be built against the boiler and potting 

 room. The south end wall will have 

 three feet of wood and the rest glass. 

 I desire to grow general bedding plants 

 and estimate that 60 degrees of heat will 

 be needed in zero weather. 



C. W. P.— N. Y. 



About 450 square feet of hot water 

 radiation will be needed for the house 

 20x50 in order to maintain 60 degrees. 

 We would suggest using three 2-inch 

 pipes, running one upon each wall plate 

 and the other two feet below the ridge. 

 Tor returns we would use four 2-inch 

 pipes under the bench on the side where 

 there is glass in the wall and three pipes 

 under the other side bench. Drop the

UPPOSE every morning during the cold season you entered your green- 

 house, you found three nice, clean, new ONE DOLLAR BILLS on the bench, 

 and these were yours for keeps. 



HOW WOULD YOU FEEL? 



The cold season would probably have 150 mornings. 



THEN you would have 450 nice ONE DOLLAR BILLS, $450.00. 



DO YOU WANT THEM? Listen! 



Manufacturers of other Greenhouse Boilers admit that $5.00 per day per 

 ten thousand feet of glass heated to 60 degrees in zero weather is a reasonable 

 fuel cost under present coal prices. 



WHAT IS YOUR FUEL COST? 



WE SAY it ought to be $2.50 per day and can prove that fuel for our 

 boilers costs but this amount. 



IF YOU use another boiler and have 12.000 square feet of glass, your cost 

 per day is probably $(>.00. Change to our boiler and your cost per day will 

 probably be $S.O0, so 150 days will give you the $450.00. Again we say: 



DO YOU WANT THEM? 



WHY the difference? It's in the CONSTRUCTION and draft travel. 



Besides, you cut out the NIGHT WATCHMAN aud save his WAGES. 



Do you want to save $100.00 on the FIRST cost of a boiler, or $450.00 

 EVERY YEAR? 



Do you doubt these statements? 



Let us tell you the facts, figures, names and places.
