it will be safe to rely upon the gas can 

 be settled better by a person on the 

 spot. It is true that in cold weather 

 the pressure is considerably reduced 

 and often drops so low that the fire 

 goes out, which, of course, is a danger- 

 ous thing for the plants in a green- 

 house, especially as it is most likely 

 to occur on the coldest nights. As a 

 rule, however, this does not occur with 

 gas from new wells, but only in those 

 where the pressure has been gradually 

 lessening. 



TWO MICHIGAN HOUSES. 



We have built two additional houses, 

 running east and west. House No. 1 

 is 21%xl25 and about fifteen feet four 

 inches to the ridge. This house is for 

 roses and has three 5-foot benches. 

 House No. 2 is 27%xl25 and about 

 sixteen feet to the ridge. It is for 

 carnations and contains four benches — 

 three of them five feet wide and the 

 other four feet wide. Will you kindly 

 tell us how many flows and returns will 

 be needed in each house? We will heat 

 with steam and are planning to use 2- 

 inch pipe for the flows and li/4inch 

 for the returns. Which is the better 

 way to run the flows, overhead or un- 

 der the benches? The boiler house will 

 be at the west end. The outside tem- 

 perature occasionally goes as low as 30 

 degrees below zero. R. L. 



For house Xo. 1, which is 21%xl25, 

 a temperature suitable for roses can be 

 secured by the use of two 2-inch flows 

 and ten li/4-incli returns. The flows 

 and four of the returns could be di- 

 vided between the two side walls and 

 the other returns could be under the 

 benches. The same piping would suffice 

 for carnations in house No. 2, which 

 is 27%xl25, when the outside tem- 

 perature is 30 degrees below zero. If 

 the ends of the houses are much ex- 

 posed it would be well to run the flows 

 either under the ridge or along the 

 purlins, and start the return coils so 

 that they will run at least partly across 

 the ends of tho houses. 



What is the Most Vital Point 

 in Grate Construction? 



Grate makers and users agree 

 that the most important point 

 is to keep the air spaces open 

 as long as possible under all 

 conditions. 



We guarantee to keep the 

 air spaces of the 



Martin Anti-rriction 

 Rocking Grpte 



open longer under any condl- 

 tions than can be done by any 

 other grate in existence. 

 The hottest fire you can build will not warp a " Martin," and it can be 

 installed without disturbing the brick work. 



We refer to Peter Reinberg, Emil Buettner, Bassett & Washburn, Wietor 

 Bros., Adam Zender, Sinner Bros., Albert Dickinson Co., and many others.

Mr. Florist, if you were shown: 



That by the installation of a good tilting steam trap 

 you would effect a saving in fuel sufficient to pay for 

 the trap in from three to six months. 



That you would increase the efficiency of your 

 steam lines by draining them of all condensation. 



That this pure hot condensation could be returned 

 to the boilers as feed water by means of this trap 

 without the assistance of pump or injector. 



Would it not Ix' a matt^^r of considerable import to yon ? 



The MOREHEAD Tilting Return Steam Trap will do this and more.
