It will take about four tons of coal to heat one 

 hundred feet of house, and one boiler will heat three 

 hundred feet with twelve tons. 



The total expense of building this kind of house 

 will average from ten dollars to thirteen dollars a 

 foot, according to circumstances. This includes not 

 only the houses, but all the forcing-pumps, &c., &c. 



The gross receipts from the four crops, will 

 amount to about live dollars a sash ; from which two 

 dollars may be deducted for expenses, leaving a prof-

 where they were not as large. 



A crop of Radishes will pay about the same as 

 Lettuce, per sash — the only advantage is, that Rad- 

 ishes will be ready for market in six or seven weeks, 

 while Lettuce will take nine. 



James Muir & Sons, who have seven hundred and 

 eighty feet of this class of forcing-houses, which cost 

 them for construction ten dollars a lineal foot, now, 

 after two years' experience, make the following ex- 

 hibit of one year's crops : 



Gross receipts from four crops $2,562 41 



Interest on $'7,800, at 10 per cent $180 00 



Coal 200 00 



Labor 300 00 



Manure 50 00 



1,330 00 



Net profits $1,232 41
