Qreenhoose Beating. 



Down in the Pocahontas coal district, 

 whence comes so large a part of florists' 

 fuel, the mines are closed to permit of 

 the consumption of surplus stocks. It is 

 said that present prices for such ship- 

 ments as go to the open market are not 

 profitable and that for the time being no 

 coal will go forward from this district, 

 except contract shipments. 



Subscribers are invited to write the 

 editor of the Heating Department, de- 

 scribing their troubles or asking any 

 questions regarding the heating of green- 

 houses, the piping or boiler-room. But 

 please do not ask us to make a choice of 

 apparatus for you. Each boiler adver- 

 tised in the Review is a good boiler, and 

 the advertisers sell them on their merits. 



AN ALABAMA HOUSE. 



As I intend to build an addition to 

 my greenhouse, I should like to know if 

 it is necessary to install another flow. 

 The house I now have is 17x100 and is 

 heated by hot water. I now have a 

 3-inch main and eleven 1% -inch. returns. 

 I know that the boiler is capable of 

 heating the new addition, which will be 

 22x100 feet. In this part of the country 

 it never gets colder than 15 degrees above 

 zero, and that is but a few nights during 

 the winter. A. B. A. 



I do not believe it will be wise or satis- 

 factory to attempt to heat the two houses 

 by means of a common flow. Much bet- 

 ter satisfaction will be secured if inde- 

 pendent flow pipes are carried from the 

 boiler to each house. F. E. 



TWIN BOILERS. 



I have two fire-box boilers, which will 

 be bricked in, and I wish to connect them 

 and run them together as a battery. I 

 want to arrange them so I can run either 

 one independently of the other. How 

 can I make proper connections? Will I 

 need more than one steam and water 

 gauge t In connecting two boilers to one 

 smokestack, which is the better way — 

 to run two separate smoke pipes to the 

 stack or connect the two pipes with a 

 "Y" and enter the stack with one pipe?

It is not always an easy matter to con- 

 nect boilers so they will work well. The 

 common way of arranging the smokestack 

 when one is used for two boilers is to set

the chimney or stack to one side of the 

 boilers and connect the two by a breech- 

 ing, i. e., a pipe placed horizontally, into 

 which the gases from both boilers enter, 

 and this is then connected with the chim- 

 ney. Besides this, each boiler should be 

 provided with both steam and water 

 gauges. Yoke the two together at the 

 top, with properly valved connections 

 with the main, to allow either to be used 

 independently, and connect them with the 

 common return, using a swing check be- 

 tween the boiler and the main return in 

 each case, besides a gate valve. Lower 

 the boilers just as far as possible below 

 the pipes in the houses. The greater this 

 distance, the less trouble will be experi- 

 enced by water backing up in the heating 

 pipes. F. R. 



PIPING IN PORTLAND, ORE. 



I am going to build two connected 

 greenhouses, each 30x150 feet. They will 

 be built on ground that slopes to the 

 east. There is about four feet of a fall 

 in 150 feet. The boiler will be at the 

 east end of the houses. The walls of 

 the houses are six feet high and the ridges 

 thirteen feet from the ground. These 

 houses are for tomatoes and cucum- 

 bers. I want a temperature of 65 de-
