Greenhouse Heating. 



The fuel problem has begun to press 

 some of the neglectful ones. The severe 

 cold wave has been of unprecedented 

 length, not only increasing coal consump- 

 tion but tying up freight traffic for an 

 unusually long' time. No grower should 

 let winter come upon him without a good 

 reserve supply of fuel. To do so is 

 simply to invite the worries that bring 

 gray hair. 



CONSTRUCTION OF IRON STACK. 



We recently ordered a new smoke- 

 stack through a local firm and we find 

 that, instead of having the joints lap 

 like a stove pipe, it has every other 

 section riveted on the outside so it 

 gives the water a chance to run into 

 the smokestack from the outside. We 

 should like to ask your heating depart- 

 ment whether that is the proper way 

 to construct a smokestack. G. F. C. 



Smokestacks are made like the one 

 described and also with one section 

 overlapping the section next below it, 

 either on the outside or on the inside, 

 the latter form being preferable. One 

 objection to having the upper section 

 lap over the outside of the lower sec- 

 tion, is that the creosote and other 

 products of combustion condense in- 

 side the chimney and, running down, 

 soak out through the cracks and stain 

 the outside of the chimney. The small 

 amount of water which will work in- 

 side the chimney will do practically 

 no harm. It has also been found that 

 a better draft can be obtained when 

 the lap of the sections is the other way. 



CONTROL OF TEMPERATURES. 



Kindly submit the following to your 

 heating expert: We have two connected 

 houses, each 18 x 75, without a parti- 

 tion between them. In each house 

 there are three benches. The outside 

 benches are against the walls, with 

 three 2-inch pipes beneath. There are 

 two pipes near the side of each nar- 

 row bench and two at each side of the 

 wide center benches, but all pipes are 

 under the benches. The houses have 

 been used only two weeks and every- 

 thing works finely except in one par- 

 ticular. The experts said we could 

 maintain a rose temperature in one 

 house and a carnation temperature in 

 the other. We find that the best we 

 can do is to produce a difference of 3 

 degrees in the north house by shutting 

 off pipes in the south house, except 

 when the wind is in the south, when 

 the difference is 5 to 7 degrees in favor 

 of the north house. How can we rem- 

 edy this? Wiat is the objection to 

 having heating pipes under rose or 

 carnation benches? These houses are 

 even-span and we find that the south 

 house somewhat shades the north house. 

 Will it be advisable to put either roses 

 or carnations in the north house?

 your greenhouses during the

 What's that— you don't know?

and And out. It has saved hun- 

 dreds of dollars for many florists 

 and may do as mucb for you. 

 Your plants and stock require 

 certain steady temperatures. 

 Use this thermomuter and you 

 will know whether they are get-

 a written record under lock and
