monoy by buying coal before cold wcither 

 comes. Then, too, you can get delivery 

 as you want it during the season of slack 

 demand and idle railroad cars. In the 

 middle of winter, shipments frequently 

 meet with long, expensive and sometimes 

 dangerous delays. 



Coal is cheaper this year than last. 

 If you are not thoroughly satisfied with 

 your coal supply, write to the advertisers 

 in the Florists' Fuel Directory iu the 

 Eeview aud get thtir offers. Do it now, 

 before you need to fire up. 



PIPING FOR A HOTBED. 



We have a boiler which is used to 

 generate steam to run an engine. Please 

 advise how many runs of pipe and what 

 size it would take to heat a hotbed six 

 feet wide, the beds being in a protected 

 place very near the boiler. Should we 

 use some of the pipe under the ground 

 and some above, and how would we get 

 the condensation back to the boiler? We 

 want to grow a general line of plants. 



V. N. 



I regret to say that I cannot answer 

 your question unless you state the length 

 of the hotbed and give more information 

 regarding the relation of the pro])osed 

 hotbed to the boiler in question. It is 

 likely that the water can only be re- 

 turned to the boiler by means of a feed 

 pump, injector or return steam trap.

EXPANSION OF COIL JOINTS. 



Will you be kind enough to give me in- 

 formation as to the best way of finish- 

 ing the ends of valved steam pipe coils, 

 so that, when only a i>art of the coil is 

 in use, the cxi)ansion of those in use 

 will not be continually breaking the 

 joints? I have the coils lying flat un- 

 der the side benches. All are returns, 

 as I use overhead flows. 8ay there are 

 four pipes in a coil and I wish to use 

 one, two or three ; tlie chances are that 

 the expansion will cause either the tee or 

 the nipple forming the manifold to 

 break. I have some just arranged in 

 straight runs, with drainage coming out 

 at one side, and other coils I have ar- 

 ranged' with short bonds, the whole coil 

 beijig 150 feet long, Init with no better 

 results. 



I only scorn to have trouble with those 

 lying flat. With those hanging one

Important 



A Capitol Boiler in the greenhouse assures two mighty 

 important results: 



First, less coal. 



Second, in case of accident, quick repairs can be made without 

 interfering with the continued heating of the house— this because 

 of the Divided Sections. 



We suggest that you communicate with florists who are using 

 Capitol Boilers. We will send you such addresses on request. 

 Get the testimony of experience. Surely you want to be on the safe 

 side of the heating expense. Send for our catalog and address of 

 nearest branch.

I will attempt to explain liow to over- 

 come your trouble, which is an easy 



matter to remedy. Instead of the plans 

 you have used, make all the returns un- 

 der any one bench of the same length. 

 I'ut an ell on each one and have it look 

 sidewise instead of down; place a short 

 nipple in the first ell and then place a 

 second ell looking down on the short 

 nipple. Make a manifold of pipe and
