Iireenhouse Heating. 



Subscribers are invited to write the 

 Editor of this Department with regard to 

 any details of greenhouse heating that 

 are not understood. But please do not 

 ask The Eeview to make a choice of ap- 

 paratus for you. The greenhouse beating 

 equipment advertised in this paper is, we 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



COAL CONTEACTS. 



The larger growers will delay the 

 contracting for coal for 1915-16 season. 

 Usually the big buyers are first in the 

 market, and it probalsly will be so this 

 year, but they will be later than usual. 

 The coal market has been lifeless this 

 season and the trade seems inclined to 

 await developments. It seems quite 

 likely the large growers near the prin- 

 cipal coal markets may adopt a differ- 

 ent policy with regard to fuel pur- 

 chases. In recent years they have not 

 contracted their full requirements, but 

 have depended on the open market for 

 a considerable part of their needs, pick- 

 ing up some cheap coal that was up to 

 demurrage. The chances are this policy 

 will be pursued so long as the coal 

 market is kept firm only by curtailing 

 production. 



A NEW ZEALAND SHOW HOUSE. 



Please give me your opinion on a 

 email heating problem. I wish to find 

 the besf way of increasing the heat in 

 my show house or conservatory, which 

 is 14x40 feet, about six feet high to the 

 eaves and twelve feet to the ridge. 

 About half of the area of the sides is 

 glass. We want a minimum tempera- 

 ture of about 60 degrees in winter, here 

 on the east coast of South Island, New 

 Zealand, where the outside temperature 

 on a few nights drops to 17 degrees 

 above zero. 



At present, as indicated in the en- 

 closed diagram, there are four 2-inch 

 galvanized pipes all around the house, 

 except at the doorway. Would you 

 prefer to take out the 2-inch pipe and 

 substitute a larger size, or increase the 

 quantity of 2-inch pipe! The benches 

 are about two and one-half feet high 

 and the pipes are under them. We do 

 not want to go below the present base 

 of the boiler, which is one foot below 

 the floor. I think the rise is not 

 enough for good circulation, and I 

 would favor putting a pipe all around 

 each side, dropping it to the ends of 

 the present pipe at the door and using 

 the present flows as returns, besides re- 

 taining the present returns. Kindly 

 state the amount of piping required and 

 the best position for it.

The sketch shows the boiler to be lo- 

 cated at one end of the house, with a 

 2-ineh flow pipe tinder each side bench, 

 running around to the door at the 

 farther end of the house, and with a I
