ABOUT THE HEAT THAT GETS AWAY 



You know that the longer the fire travels, con- 

 stantly coming in contact with the water-ways, 

 the more the heat is harnessed and the less goes 

 up chimney. So far so good— but of still greater 

 importance is the extracting or absorbing of the 

 greatest amount of heat directly in the combustion 

 chamber when the burning gases are hottest. This 

 is what is accomplished by the "Burnham" cross fire 

 channels with their side Hue openings, which chan- 



nels are surrounded on three sides by extra deep 

 water-ways. The heat that these deep water-ways 

 fail to absorb is then practically all taken up by the 

 fire travel in its journey three times the boiler's 

 length. So these are the reasons why, for green- 

 house economy, you can't beat the "Burnham" Hot 

 Water or Steam. 



Burn hard or soft coal. Send for the new boiler 

 catalog.

55 degrees. The houses run east and 

 west, with a glass gable in the west end. 

 The boiler is under the shed at the east 

 end. How should each be piped for steam 

 and what horse-power of horizontal tu- 

 bular boiler is required? We get water 

 from a spring-pond and should like to 

 get your advice as to the water plant. 

 What can we do to avoid a boiler-pit? 



H. O. 



Regarding the direction and piping of 

 your houses, will say my personal profer- 

 euce with even-span houses is that they 

 run north and south, with the work-room 

 and heating plant at the north end. 



Houses No. 1 and No. 2 should each 

 be provided with a 3-inch flow under the 

 ridge and fourteen IViinch returns the 

 length of the house. Houses Xo. .3 and 

 No. 4 should each be provided with a 

 2»l.-ineh flow under th(> ridge and ten 

 114-inch returns, while house No. 5 

 should have a 2-inch riser under the ridge 

 and seven IVi-inch returns. 



By installing a return steam trap ycm 

 can arrange the boiler on the level of 

 the greenhouses. This will require the

overhead risers as suggested, and all the 

 water of condensation will be returned 

 into a hot well, from which it can be 

 lifted to the boiler by the steam trap. 

 The water plant can be arranged by use 

 of a ram, windmill or power pumj) driven 

 by motor, gas engine or steam engine. I 

 .am inclined to believe that either gaso- 

 line or steam power will be most satis- 

 factory. The water would be delivered 

 direct to mains or into an elevated stor- 

 age tank as desire<l. 



If you use ii gravity system, the \v;iter 

 level in llie boiler should be at least two 

 feet below the level of the lowest radi- 

 ating pipes ill tiie houses; iiuire would 

 be better. The lioilers should h;ive ;i 

 rated capacity to c;iriy },(iiii) square feet 



of radiation or more. One return tubu- 

 lar boiler, rated at forty horse-power, 

 should be sufficient to heat this plant.

The Market 



There has been no change in the 

 state of the market. May 25 it was 

 about as poor as it was last week, and 

 were it not for the prospects of a good 

 Decoration day trade the outlook would 

 be discouraging. We are having hot 

 weather and it shows on the quality of 

 the stock. Many of the carnations ar- 

 rive badly used up. Home-grown stock,
