White wood, per thousand $4 go 



Wood prepared with sulphate of copper 6 20 



Hard wood (oak) 8 00 



The mean duration of these stakes is as follows : 



Stakes of white wood, 10 years, expense .per year $0 48 



" sulphated wood, 15 years, expense per year o 40 



" oak, 20 years, expense per year o 4a 



From this^ it follows that whatever be the nature of 

 the wood employed, the thousand stakes represent an 

 annual expenditure of about $0.50. Now, in Burgundy, 

 about 9,200 plants are set to the acre, and each plant 

 must be provided with a stake. 



We thus have 9,200 stakes to the acre, givihg rise to an annual ex- 

 penditure of. „$3 68 



To which add, for planting, taking up, and sharpening the stakes, 



for the same extent of surface „. i 92 



Plus interest, at 5 per cent, on the cost of stakes, for the whole time 

 of their duration, $42.75, which, divided by 15 years, their mean 



duration, gives, per year 2 85 



t 



Total $8 45 



Therefore, staking the vines in Burgundy, costs 

 $8.45, yearly, per acre. 



In Champagne, this operation gives rise to the fol- 

 lowing expenditure : 



The stakes, per thousand, cost : 



In white wood, per thousand $8 00 



In oak, " 12 00 



The mean duration of these stakes, is : 



White wood, 10 years, cost per year $0 80 



Oak, 1 5 years, cost per year o 80 



In Champagne, as we have already stated, about
