92 THE CULTURE OF THE GEAFE. 



in the summer for other uses, but much of the strength 

 of it will have escaped by evaporation, or have been 

 washed into the earth ; and where labor is so high as it 

 is with us, the cost of working and making this heat, 

 and removing it after the fruit has ripened, will be very 

 nearly equal to its value. 



The cost of this manure at Salem, Mass., is $4.50 the

 cord, according to the distance it has to be carried ; mak- 

 ing the whole cost of the quantity required as above, in 

 round numbers, $700. 



On the rafters of a house of this length of border, 

 which is to be winter-forced, eight hundred pounds of 

 grapes would be a very large aveeage

 which would not be aifected by this heat 267 



on the border, one third of this quantity 



would be as much as could be relied upon, 1067 pounds, 

 and this is more than is usually produced 

 in most graperies ; but my experience warrants me in 

 placing it at about this amount. 



To judge of the practicability of the plan, a short cal- 

 culation wil . be necessary : —
