How to Keep 

 Your Chimney 

 Cool 



First — Don't skimp your boiler. 

 Buy one large enough so you don't 

 have to leave the draft door open a 

 good part of the time and force the 

 burning gases so rapidly that they 

 reach the chimney before the heat 

 is more than half extracted. 

 Second — Buy a Bumham, because 

 it is the only boiler with cross fire 

 channel having side flue openings, 

 or with a fire travel three times the 

 boiler's length before reaching the 

 smoke outlet. No other cast iron 

 sectional boiler is constructed 

 especially for greenhouse heating.

tain 120 square feet of heating surface. 

 To build such a heater of li/^-inch pipe 

 will require 240 lineal feet of pipe. The 

 details of the construction of a pipe 

 boiler include the construction of a 

 brick furnace in which to arrange your 

 heating surface. It will probably be 

 not much more expensive and possibly 

 much more satisfactory to buy one of 

 the moderate priced heaters advertised 

 in the Review. L. C. C. 



CEMENT FOR CAST-IRON PIPE. 



Portland cement makes a good joint. 

 I have one house piped with 4-inch pipe 

 and the joints were made with Portland 

 cement and have been used for fifteen 

 years. The joints arc made the same as 

 with iron filings; that is, first a layer 

 of oakum and then cement, filling the 

 sleeve nearly full, and then a layer of 

 oakum, plastering over the outside with 

 cement. The advantage is that one can 

 make three joints with cement while he 

 can make but one with the iron filings. 

 This is in answer to the inquiry of C. J. 

 in the Review for August 27.

MUSHROOM HOUSES. 



We are building two mushroom houses 

 16x100, with a rhubarb forcing house on 



the north side, 16x100. On the south 

 side we will put a greenhouse and boiler- 

 room, with office, packing house, etc. 

 But we may not put up the greenhouse 

 this fall. How much pipe will it take 

 to heat the mushroom houses to 50 de- 

 grees in zero weather? Also, what size 

 of boiler will be needed? H. H. C. 



Each house 16x100 should be provided 

 with 600 square feet of radiation to 

 maintain a temperature of 50 degrees 

 during severe weather. If you use 1^- 

 inch pipe and hot water at 180 degrees 

 it will require 1,200 feet of pipe. If 

 2-inch pipe is used, 960 feet will give the 

 same amount of radiation. To handle 

 the three houses contemplated the boiler 

 used should be rated at not less than 

 2,000 square feet of radiation.

TOO LITTLE RADLVTION. 



I am building two greenhouses, each 

 17x60, which I will heat with hot water, 

 using 4-inch pipes. These houses are 

 built north and south, with the boiler- 

 shed at the north end. They have con- 

 crete walls all around and no exposure 

 except the roof. Will it be safe to run 

 a 4-inch flow half-way up the roof and 

 drop at the south end into three 4-inch 

 returns under three beds? Will it be

all right to couple both the returns, one 

 .for each house, on to one pipe at the 

 •boiler? The boiler is in the center of 

 the two houses. My idea is to run a flow 

 pipe in each house, but to couple all six 

 returns into one pipe at the north end
