What is the Host Vital Point in Grate Construction? 



Grate makers and users agree that the most important point jn to keep 

 the air spaces open as long as possible under all conditions. 

 We guarantee to k«ep the air spaces of the 



MARTIN ANTI-FRICTION ROCKING GRATE 



open longer under any conditions than can be done by any other grate 



in exiatence. i 



The hottest fire you ^an build will Hot warp a "Martin" and it can be 



installed without disturbing the brick work. 



We refer to Peter Reinbery, Emil Buettner, Bassett & Wasbbom. WiMor Bros., A<laia 

 Zender, Sinner Bros., Albert Dickinson Co., and many others. "z 't^y^::^- • f ; "' yi;

KEEP BOILEBS FILLED. 



Can some of our experienced florists 

 give us the best method generally pur- 

 sued with steam boilers while they are 

 idle during summer? Are they kept 

 dry or should the water remain in them? 



What percentage of boiler insurance 

 on greenhouse steam boilers is carried; 

 also, what percentage of accidents 

 through boilers exploding occur, say 

 in a period of three years? The best 

 information on this will be appreciated. 

 Our locality is a gulf coast town.

The usual custom is to keep the boil- 

 ers filled with water during the sum- 

 mer. The oxidation of the inner sur- 

 face of the boiler and heating pipes 

 is, of course, due to the air contained 

 in the water, and this has been largely 

 expelled from the water which has 

 been in the boiler for some time. If 

 this water is drawn off, the wet sur- 

 face of' the boiler is again brought into 

 contact with the air, and when the 

 boiler is refilled in the fall the water 

 will again contain a considerable 

 amount of air and the oxidation will 

 be greater than had the water been 

 unchanged. The advantage from keep- 

 ing the boiler filled during the summer 

 is even greater in hot water plants, as 

 then the heating pipes can be kept 

 filled as weU. 



Comparatively few florists, who use 

 low pressure steam for heating, have 

 their boilers insured. While we have 

 no accurate data, the number of and 

 loss from explosions is quite small. 



FIFING FOB ILLINOIS HOUSES. 



I have six houses, from ten to fo^r• 

 teen feet wide and nine feet to the 

 ridges and five feet to the gutters. 

 They are fifty-six feet long and run 

 north and south, with a potting shed 

 and boiler room across the north end 

 of the range. The south ends have 

 three feet of glass. These are on a 

 slope to the west so the roof of the 

 east house comes to the ground while

Condensation is the purest kind of boiler feed water. Don't waste it. Return It directly to the boiler

Two Tank Traps vs. One Tank Traps 



Orders for our TWO TANK TRA.PS are 



being repeated and quadrupled by the largest 

 manufacturers In the Tnited States. We will fill 

 your order just as quickly as the repeat orders. 



The Canadians killed Reciprocity, but they 

 buy our traps and pay big duties on them. This 

 is good evidence that our traps are a huge success. 



Let US r«tum the oondenaatlon to your 

 boilers and save the heat units. Our traps do the 

 work forone-tenth of thesteam required by pumps. 



Will the saving pay? 



Try our traps and be conTlnc«d.
