156 FOEESTEY WOEK 



2 feet high. Against these the bark is placed in a leaning 

 position, keeping the rough side exposed (Fig. 15, B). 



A small space should be left between the pieces to 

 allow air to have free play. The larger pieces from the 

 trunk are used as covers. If allowed to get very wet 

 and mouldy, the quality of the bark deteriorates. If this 

 should happen, the racks should be thrown open for a 

 time or the bark turned. 



It is ready for carting or stacking when it is hard and 

 brittle, breaking to pieces easily. In good weather this 

 should take from ten days to a fortnight. In wet 

 weather it takes much longer, and constant turning is 

 necessary. If it gets mouldy, it must again be brushed 

 before being sent to the tanneries. 



At one time bark was usually chopped up into small 

 pieces before being delivered, but this is seldom practised 

 now. It is better to send it as it seasons direct from the 

 drying ground to the tanneries rather than stack it. 

 There is small enough profit, even in favourable weather, 

 without the extra cost of twice loading and carting and 

 stacking. 



Measuring Felled Timber. 



The usual method adopted for measuring in this 

 country is that known as the " square of J girth measure- 

 ment," which makes an allowance of 21 \ per cent, for 

 wastage, as compared with the true cubic contents. 



In applying this, the girth is taken in inches midway 

 between the ends of the log, allowance being made for 

 bark, and the figure divided by 4, giving the J girth.
