The Rorists' Review 



40 Years of Burnham Boiler Making: 

 How It Concerns Your Pocketbook 



IS' 



IHEN a concern has a poor or faulty article, they must 

 make all haste and try and improve it. The com- 

 plaints of users generally induce them to put im- 

 provements on the market before they have really been 

 thoroughly proven to be improvements. 



As a result, you and the other fellow do the experi- 

 menting that the maker couldn't afford to wait to do. You 

 become the experimental department for them. It's a 

 cheap way for them to find out, but is generally rather 

 expensive for you. 



Now take a concern like the Lord & Burnham Com- 

 pany—thoroughly established, with forty years of boiler- 

 making experience and a line of boilers that for years 

 and years have been giving splendid satisfaction. Having 

 a splendid boiler as a basis, we don't have to hustle 



through any half-thought-out improvements and ask you 

 to try them out for us. We are in a position to spend 

 months, and often years, on an improvement. Today we 

 believe, and we have had many customers who believe 

 likewise, that the Burnham Boiler is the best cast-iron 

 boiler made. 



That's the reason why, when you buy a Burnham 

 Boiler, every part works the way we say it will work. 

 That's why it heats as much radiation and as economic- 

 ally as we say it will. That's why it can be erected so 

 easily. That's why the repairs are so few. That's why 

 the Burnham Boiler is the successful greenhouse boiler it is. 



If this is the kind of safe and sure boiler you want, 

 we can ship it the same day your order is received. If in 

 a particular hurry, wire at our expense.] A' Hi

PIPES CLOGGED WITH WATER. 



I am enclosing a sketch of the heat- 

 ing system of seven houses of which I 

 am foreman, and should like to have 

 you criticise the arrangement and sug- 

 gest the best way to improve it. The 

 piping has not been giving satisfaction. 

 Last winter, with twenty pounds of 

 steam at the boiler, it was impossible 

 to keep a proper temperature. I should 

 like to make just as few changes as 

 are necessary to bring the system up to 



a fair degree of service. The houses 

 belong to the vegetable department of 

 a well known firm of growers in south- 

 western Pennsylvania, who also have a 

 range of flower houses in connection. 

 A steam heating system is used and the 

 water is returned by gravity. 



The houses do not run exactly east 

 and west, but for the sake of clearness 

 of description I will suppose that they 

 do. The boiler is near the southeast 

 corner of the range. Beginning at the 

 south side of the range, houses No. 1, 

 2 and 3 are each 18x180, five feet to the 

 gutter and ten feet to the ridge. They 

 are three-quarter span, with 11-foot
