Fuel dealers complain that the very 

 florists who made the biggest ' ' holler ' ' 

 when caught short of coal by last win- 

 ter's car famine are the ones who are 

 deaf to all pleas to buy now and take 

 in at least a part of the season's supply. 

 The fore-handed growers are filling their 

 bunkers to the greatest capacity. 



BURNS TOO MUCH COAL. 



We have a greenhouse 17x120 feet 

 and ten feet to the ridge, with cement 

 walls four, feet high. It is heated by a 

 Buffalo boiler, which feeds a 4-inch 

 flow. The flow branches into two 3 inch 

 pipes, and returns in ten 1-inch pipes on 

 one side and in eight 1^/4 -inch pipes on 

 the other side, under the benches. The 

 flow pipe is at the ridge of the house 

 and has about two inches &f a rise to 

 the branches. The house itself has 

 twenty inches of a fall toward the 

 boiler, which is in the south end of the 

 building. The return pipes have about 

 thirty-six inches of a fall. We wish to 

 keep a temperature of 60 degrees in 

 zero weather. We can raise the desired 

 heat,, but the expense for fuel is alto- 

 gether too high — about double that of 

 other florists. The boiler pit is two feet 

 deep and cannot be put any lower on 

 account of the drainage. Any informa- 

 tion you can give concerning this 

 trouble will be appreciated. I am lo- 

 cated in southern Ontario. W. B. 



There is evidently something radically 

 wrong with the heating plant, as the 

 amount of radiation is twice as great 

 as is necessary. There should be no 

 difficulty in maintaining a temperature 

 of 60 degrees with three 214-inch flow 

 pipes and nine 2-inch returns. 



It is not advisable to use anything 

 smaller than 2-inch pipe for the returns 

 when a house is more than seventy-five 

 feet in length, unless the returns are 

 well above the top of the boiler. One

important step, therefore, in the solu- 

 tion of the difficulty, would be to 

 change the returns. The circulation 

 could also be improved by giving the 

 flow pipe a slight fall instead of a rise. 

 The return pipes should be kept as high 

 as possible an^ should not drop more 

 than one inch in ten feet. A material 

 benefit can be secured by merely chang- 

 ing the level of the pipes, as indicated, 

 and this alone may suffice to bring down 

 the coal bill. Another change, in case 

 there is an objection to putting in larger 

 pipe, would be to use a closed system 

 under pressure.

I have a range of four greenhouses, 

 here in eastern Massachusetts. Three 

 of the houses are parallel, but are sepa- 

 rated from each other by wide, open 

 spaces. They are connected and pro-
