PRACTICAL FORESTRY. 



There are, however, several advantages accruing from this 

 method, not the least of which is that the bark may be 

 chopped up as it is removed from the drying-stands, thus 

 saving the expense of stacking. Chopping the bark can also 

 be done by the workmen during wet weather, and when not 

 otherwise engaged. 



In computing the quantity of bark before stripping, we 

 have found the following data fairly reliable : 



(1) A well-balanced tree with a good head will yield about 

 6 cwt. of bark for every ton of measurable timber, if 

 branches down to an inch in diameter are peeled. 



(2) Hedgerow trees usually yield about a ton of bark to 

 every three tons of timber. 



(3) Trees growing in close woodland are usually thin 

 barked, the yield being about a ton of bark to every 4J tons 

 of timber. 



(4) Oak poles will average five tons of timber to a ton of 

 bark. 



Tall, clean stems, as when the poles are grown thickly 

 together, with small heads, give the smallest yield in propor- 

 tion to the quantity of timber, and short stems with 

 spreading heads the largest. 



Profit and Loss of Barking Oak. At the highest 

 price now obtained for the best class of oak bark, 

 viz. : 10s. per ton, the profit, after paying expenses 

 of stripping, &c., is indeed small, and brings it within 

 the pale of discussion whether should the price of bart 

 go on decreasing, it is wise to have it removed. For 

 industrial purposes it must be admitted that the quality of 

 the oak timber is materially affected by the season at which 

 the tree is cut down, viz: when the tree contains the 

 largest quantity of sap. 



The main question, however, to be carefully considered is 

 whether or not the average market price of the bark is com- 

 mensurate with the expenses of production, adding thereto 

 that proportion of the value of the timber lost by the 

 deterioration of the sapwood. The total cost of production 

 has been carefully gone into, with the following result 

 per ton!
