THE SOIL CARRIER IN USE. 



SAVES TIME. LABOR \ MONEY 



We call your attention to Our Gravity Carriers for conveying soil into and out of 

 greenhouses. You are aware of the great amount of labor necessary for changing the 

 loam in your benches. It requires but a few feet of our Gravity Carriers to reduce 

 this expense. 



Carriers are made in eight and four foot sections, which can be instantly joined ; 

 the rollers are of the best seamless steel tubing, ball bearing, and are 14 inches in length 

 by 2^4 inches In diameter. Cut shows how they operate. 



A run of carrier is set tip with one end projecting through a window and a cart 

 containing the loam is placed at this end. The loam is shoveled into the boxes, which 

 are pushed or conveyed by gravity into the house and dumped into the benches. Empty 

 boxes are pushed back to cart over same run of carrier. When the beds within a con- 

 venient radius are filled, the carrier is set up at another window and the work contin- 

 ues until all benches are filled. For removing soil the process is, of course, similar. 



We shall be pleased to furnish further details relative to construction and dura- 

 bility of the carriers ; also, upon receipt of information relative to size of your green- 

 houses, furnish an estimate of the cost of a system for your requirements.

in this case is that the returns are even 

 below the top of the heater. 



If the piping is properly arranged, it 

 should be possible to improve the cir- 

 culation by closing the system by at- 

 taching a mercury generator. If the 

 system is to remain an open one, use 

 larger pipes and lower the heater.
