NEWS AND NOTES. 



Mr. Lincoln Crowell sends the following interesting item: 

 Last winter I had occasion to make some measurements of 

 hewn rock elm export timbers to determine the relation of their 

 volume in cubic feet to the log scale of the unhewn log. Of no 

 hewn rock elm timbers, having an average cubic content of 47.5 

 feet, I found that there was 13 plus board feet S. D. C. log scale 

 per I cubic foot of hewn timber. About 12 per cent, of the log 

 scale volume of the merchantable bole (not deducting for de- 

 fect) was unsuitable for export timber because of pipe rot, ring 

 shake, or black knots. 



Coal tar creosote, which was scheduled for a 5% duty under 

 the new tariff law, has been returned to the free list. This was 

 the result of evidence submitted showing the beneficial results 

 of wood preservation as a factor in forest conservation, and the 

 handicap which even 5% would impose. 



As shown on another page, preservative processes are more 

 and more widely employed to secure longer life for wooden struc- 

 tures. This increase in the use of preservatives has led to their 

 reduction in cost. The Carbolineum Wood Preserving Company, 

 of New York, announces reduction in price of their preservative 

 to from 90 cents to $i-oo per gallon, according to quantities or- 

 dered. This Company also sends out bulletins of information 

 that occasionally go beyond the mere advertising line. One of 

 the latest points out the desirability of supplementary surface 

 treatment of treated timber, after the timber has season-checked, 

 either by brush or spray, the latter method preferably, as it per- 

 mits reaching splits, checks, joints, that can never be reached by 

 the brush. 



No forester in Sweden is found without an increment borer 

 as a steady companion. This borer was originally designed by 

 Pressler half a century ago, but it is only within a few years 

 that a Swedish manufacturer, Mattson, has perfected the in-
