HEATING. 



1 wish to heat, by hot water, a small 

 )>laee, 10x20, side walls 4 feet, 10 feet 

 1o I'idge, south end glass, north end pro- 

 tected, to maintain a night temperature 

 of 5ij degrees. How many flows and re- 

 turns of 2-inch pipe will it require? 1 

 wish to use same boiler that I heat my 

 house with now. Top of boiler is two 

 feet above floor of greenhouse and green- 

 house is five feet away from house. Could 

 pipes be run to it? And what is the best 

 way to protect them. F. M. 



in." 



Replying to F. M., a 2-inch flow pipe 

 sliould enter one end of the greenhouse 

 near the ridge, then dropping down under 

 one of the side benches, branch into four 

 2-inch pipes, which should ruu along two 

 sides and across one end of the house, 

 then reducing into one 2-inch return and 

 running back below the ground to the 

 boiler in the cellar of the dwelling. The 

 pipe must be down-hill from the time 

 it leaves the main flow pipe in the dwell- 

 ing until it reaches the boiler again at 

 the return. The best way to protect the 

 pipe above the ground is to wrap it with 

 %-inch hair felt, over which should be 

 placed the ordinary sectional asbestos 

 <?overing for 3-inch pipe, which has a 

 canvas outer covering that can be readily 

 painted to make it water-proof. The re- 

 turn below the ground should be well 

 wrapped with hair felt or asbestos, ami 

 enclosed in a wooden box of 2-inch thick 

 plank. 



If the greenhouse were heated by an in- 

 <lependent boiler, three pipes under each 

 bench would answer, but in a small house 

 heated from the dwelling system, where 

 the fire is usually checked at night, more 

 heating surface is required in the green- 

 house. Henry W. Oibbons.

VENTILATION. 



A good deal has been said and written 

 about giving roses and carnations plenty 

 of air, especially the latter, but 1 believe 

 the full importance of the matter has not 

 yet been generally understood. I believe 

 that few, if any, growers yet luive sufli- 

 tient ventilating space on their houses to 

 enable them to give as much air in sum- 

 mer as they .should. 



On a house about 30 feet wide, aud this 

 is getting to be the most common width 

 around Chicago, I believe that the venti- 

 lators should be four feet deep and con- 

 tinuous, and that there should be venti- 

 lators of this size on both i-ides of the 

 ridge. They should open from the header 

 and not from the ridge. The ventilators 

 can then be kept open in rainy weather 

 without admitting much of the rain. In 

 ordinary summer weather both sides 

 should be wide open, insuring a really 

 active circulation of the air. In a few 

 carnation houses I have seen where the 

 summer ventilation was what seemed to 

 be unnecessarily large the plans were 

 60 vigorous and produced such fine blooms 

 on stout stems that the difference in their 

 favor was strikingly apparent. 



In winter time the expense of the extra 

 ventilators will be well repaid also, for 

 you can then nearly always put on a crack 

 of air on the opposite side from that 

 from which the wind comes, and get ven- 

 tilation without any chance of a chill 

 wind striking the plants. I Iwlieve that 

 this double ventilation on tlie roof is far

" For Chrysanthemums, we use 

 OSAFE OUST with the best results 

 by freely dustinp with it imtil the 

 delicate blooms come, then we are a 

 bit shy of it to prevent any stainiDR 

 of the petals, but during the green 

 state, even in bad weather, there is 

 no trace of fungus, and we keep free 

 of the spot. I have recommended it 

 to many gardeners, and so far my 

 acquaintances have found it very 

 valuable. In common with many 

 Gardeners and Florist.^^. I have foimd 

 it of great value in checking the 

 BUST our CABNATIOZrS. It is 

 not expensive to use. for by using in 

 air bellows it ditluses itself every- 

 where, and is, in my judgment, a 

 viiluable every day article."

preferable to any attempt at using side 

 ventilation, which has several drawbacks. 

 With eight feet of continuous ventila- 

 tion on carnation houses the inside tem- 

 perature in summer time could be kept 

 nearly the same as in the open air and 

 not 10 to 15 degrees higher, as is now the 

 rule. Aud this would largely do away 

 with any necessity of shading carnation 

 plants after benching. Of course, a very 

 light shade for a few days would be 

 wise in hot, sunny weather, but only for 

 a day or so, and so light that there would 

 be only the slightest check in the sun's 

 rays. Charles Handei,,
