tent of the pieces. One set of specimens was treated with creo- 

 sote similar in composition (as shown by fractional distillation) 

 to the creosote from which the fractions were obtained. 



The results indicated that "the lig-hter fractions of creo- 

 sote, when separated by distillation and separately injected into 

 sap loblolly pine, will volatilize much more rapidly than the frac- 

 tions combined in the original creosote. This might be explained 

 by the supposition that when creosote containing both low-boil- 

 ing and high-boiling oils is injected into wood, the light oils 

 volatilize chiefly in the outer portions of the wood and leave oil 

 that is much less volatile. The outer cells thus become more or 

 less sealed and tend to prevent the volatilization of the lighter oils 

 in the interior of the wood. 



"It is possible that with a light treatment, where the ducts and 

 cells are not filled with creosote, but the cell walls are simply 

 coated with oil, the tendency here noted would be very much less 

 apparent. Nevertheless, it may be inferred that a creosote, to 

 be of most value, at least for treating loblolly pine, should con- 

 tain considerable quantities of high-boiling fractions, which ap- 

 pear to plug up the outer cells, and so insure the retention of the 

 lighter oils in the interior of the wood."

This report deals entirely with forest fires and is a resume of the 

 progress made during 1909-1910. The present number of town 

 and district fire wardens is given as 605, with an average district 

 of 2,480 acres. A marked increase in efficiency of wardens from 

 year to year is noted, especially in the matter oif organizing to pre- 

 vent and quickly suppress fires. The use of simple fire fighting ap- 

 paratus, especially bucket pumps for one or for two men, is advo- 

 cated, and is made possible by the absence of mountain topography 

 and abundance of running water. A cut is shown of the two- 

 man bucket pump. This has been of use both in extinguishing 

 light fires and in controlling back fires in a heavier blaze. The 

 report discusses the question of railroad fires and methods of 

 control, and the operation of the brush burning permit law.
