houses. This would give a rather more 

 even distribution of the heat and there 

 would also be some benefit f roA placing 

 the pipes under the benches, as they 

 would furnish bottom heat and this 

 tends to promote the growth of the 

 plants upon the benches. 



A HOUSE IN SOUTHEBN TEXAS. 



Kindly advise me as to the best way 

 to pipe a greenhouse 32x100 feet, four 

 feet to the eaves and eleven feet to 

 the ridge. The coldest weather here is 

 about 12 or 15 degrees below freezing 

 point, and there are, altogether, only 

 from three to five weeks of cold weather 

 in the whole winter, but the cold snaps 

 are always accompanied by high north 

 winds. I have been planning to run 

 two 2-inch flows from the boiler 

 straight up to tjae roof of the shed, 

 where I would ''attach tees, connect 

 with the expansion tank and run two 

 2-inch flows near the ridge, with a fall 

 toward the farther end. From these 

 I would run two 2-inch returns one each 

 side at the eaves, two under the mid- 

 dle bench and one on each side between 

 the middle bench and the eaves. This 

 would make ten runs of 2-inch pipes 

 in all, or would it be better to use 

 twelve runs of 2-inch pipes? 



, •': W. S. H. 



The number of pipes will depend con- 

 siderably on the exposure of the house 

 as well as the temperature desired. If 

 it will do no harm to allow the temper- 

 ature to drop to 50 degrees in the 

 colder nights, ten 2-inch runs would 

 probably answer, but if it is necessary 

 to maintain 60 degrees, more radiation 

 would be desirable. At any rate, the 

 use of two 2-inch flow pipes will not 

 su£Sce in a house of this size. At least 

 two 2V^-inch pipes would be needed; 

 or, if 2-inch pipes are preferred for the 

 flows, put in four 2-inch flows and eight 

 2-inch returns.

There 



Is Economy 



in Setting Boilers 



in Batteries 



■^^•'-; V-^: * 



Economy, because you have an absolute control of the coal you bum. You 

 run only one boiler when one is needed; more, when more are needed. You are 

 not running one immense boiler with its big grate to keep firing, no mattet what 

 the weather is. . -, , -. :^i, .« 



Boilers in batteries mean not otily 

 just the amount of heat you need and 

 no more, but a tremendous saving in 

 coal and labor. 



Then think of the ease with which 

 the sections of even our large 36^nch 

 boiler can be handled when setting 

 up, in comparison with the tremendous 

 task of installing one of those mam- 

 moth wrought-steel boilers. Think of 

 the masonry work necessary— think 

 of the tubes that in a short time will 

 need to be replared. 



So much for batteries— now a word 

 concerning the "Bumham" itself. 



It's made especially for greenhouse 

 work, and it works as no other boiler 

 works- not only a matter of coal 

 economy but time economy. It's 

 quickly fired, quickly cleaned, and wa 

 honestly believe it harnesses up more 

 heat from less coal than any greenhouse 

 boiler made. 



Here is a suggestion: Order your 

 Burnham now. Then we will set it 

 up at the factory at once and give it a 

 thorough pressure test. Then we will 

 take it down, mark it, set it aside and 

 hold it for you. When you are ready, 

 the boiler will then be ready —no delays. 



A good many of our orders for this fall's delivery were booked along in Feb- 

 ruary. The boiler costs you nothing until deUvered, and it protects you against 

 delays of the rush season. 



Don't simply say— "Why, that's a good idea," and then not do anything. 

 Send your order and send it this very day.
