bars, will usually prove to be more durable, 

 as the rod prevents the sides from spreading. 



Most hotbed sash consist of three rows of 

 glass so laid that the water will flow length- 

 wise of the sash. For this purpose 18 panes 

 of 10 x 12-inch glass are required. Sash hav- 

 ing four rows of glass are not uncommon, 

 but the extra bar and laps obstruct so much 

 light that they are less satisfactory, and they 

 are rapidly going out of use. They require 

 28 panes of 8 x lo-inch glass. Sash may be 

 purchased either, glazed or unglazed. When 

 time is plentiful and the workman is handy 

 with tools, they may be glazed at home at a 

 considerable saving in cost. 



Well made sash may be had, unglazed and 

 unpainted, at from $i to $1.25 each. The 

 same sash glazed and painted cost from $3 to 

 $3.50 at the factory. The price of glass varies 

 greatly from year to year, but on the average 

 will cost from 75 cents to $i per sash. 

 Roughly speaking, the sash, putty and paint 

 will cost about $2.25, leaving from 75 cents 

 to $1.25 for the labor of glazing and painting. 

 Sash of varying sizes are sometimes seen, but 

 their use is not advised. It is seldom possible 

 to replace them as cheaply as when standard 

 size sash are used.
