There are more MORKHKAD TRAP|LJnstall«d in srreenhbuses than of all other 

 makes of steam traps combined. The Morehead is distinctly a florist's trap. Every 

 feature of its construction has been treated with a view of meeting the special needs 

 of the florist. >

Greenhouse 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 Review to make a choice of ap- 

 paratus for you. The greenhouse heating 

 equipment advertised in this paper is, wo 

 believe, the best for the trade to buy, 

 and each article the best in the special 

 field of its adaptation. 



SMOKEIJiSS COAL AT CHICAGO. 



The smokeless coal market, which has 

 been wavering a little for the last 

 couple of weeks, has strengthened up 

 again in both lump and egg and mine- 

 run prices. Of course the colder weath- 

 er had a good deal to do with it, be- 

 cause that started the householder to 

 buying larger sizes, while the need to 

 fill up their bins has caused the apart- 

 lAent houses also to increase their or- 

 ders with the retail dealers. To a cer- 

 tain extent, however, the tighter mar- 

 ket is due to a decrease in the car sup- 

 ply through the smokeless field and 

 hence freedom from any tendency on 

 the part of any producing company to 

 speculate by sending in a great deal of 

 unsold coal. It was this tendency that 

 weakened the market some time ago. It 

 is the opposite of this tendency now 

 that is strengthening the market. To 

 be sure, Chicago and surrounding ter- 

 ritory is buying quite a good deal of 

 smokeless, but it is not in position to 

 absorb an unlimited amount. 



COAL OB NATURAL OAS? 



I have a No. 9 Kroeschell boiler, with 

 which I expect to heat four greenhouses, 

 each 25x125. My three-quarter coal 

 costs me, delivered in the boiler room, 

 9 cents per bushel. In this part of Ohio 

 I can get natural gas for 20 cents per 

 thousand feet. Which, in your opinion, 

 would be the cheaper fuel, and about 

 how much cheaper? The pipes are all 

 laid for gas, but I have never used it. 



J. W. N. 



Unless the coal is of unusually good 

 quality, the gas at the price mentioned 

 is likely to be about as cheap in first 

 cost as the coal and would have the

HIGHEST POINT IN SYSTEM. 



I enclose two sketches, showing two 

 proposed methods of piping my green- 

 house. Will you please inform me which 

 is the better way to arrange the flow 

 pipe, according to sketch No. 1 or 

 sketch No. 2? Should the pipe run 

 straight up to a high point above the 

 boiler, with an expansion tank attached, 

 and then drop gradually to the side 

 coils, returning to the boiler as in sketch 

 No. II Or would it be better to run 

 the flow pipe gradually up one aide of 

 the coils to a high point, connect there

 the highest point in the system is as
