Washington : Owing to a falling off since August 1 of 



"irarly 50 per cent in shipments of creosote from rngland 

 and Germany, v;hence comes all "but a small part of the im- 

 ported oil used by wood preserving plants in this country, 

 American manufacturers have taken steps which, says a report 

 compiled by the forest service, it is estimated will increase 

 production of the domestic article "by about 25 per cent. The 

 imported oil ore?, inaiily forms about 65 per cent of the total 

 used in the United States, where creosote is the most im- 

 portant wood ^resc-rvative. 



The statistics gathered show that wood preserving 

 is one of the most rapidly advancing industries in the coun- 

 try. In 1895 there were fifteen plants in the United States; 

 in 1914 there were 122 plants of all kinds, 100 being of the 

 pressure -cylinder type. Ninety-four of these plants last 

 year used more than 79 million gallons of creosote oil, more 

 than 27 million pounds of dry zinc chloride, and nearly 2% 

 million gallons of other preservatives, such as coal tar anc 

 crude oil, treat in.? a total of nearly 160 million cubic feet 

 of timber; an increase of about 7 million cubic feet over 

 1913, and of 35 million cubic feet over 1912.
