266 Forestry Quarterly. 



Locust and Water Locust are poorly thought of but are used for 

 crating and for floors which are to be covered with better wood. 

 Live Oak is used to a very limited extent for furniture and 

 vehicles, and somewhat more commonly for fuel. Sassafras is 

 used for flooring, wardrobes, clothes chests, and dugout canoes. 

 Sweet Magnolia is used to some extent for boxes and excelsior.

Paper Pulps from Various Forest Woods. By H. E. Surface. 

 Forest Products Laboratory Series, U. S. Forest Service. Wash- 

 ington, D. C. 1912. Pp. 29. 



This bulletin embodies the data of experiments in chemical 

 pulp production from twenty-two species, seven of them broad- 

 leaved trees. The list includes a few which have already been 

 used commercially to a slight extent. For each species are 

 given the cooking conditions used, together with the resultant 

 yields, and qualities and general characters of the pulps. 



A unique feature of the bulletin is the inclusion of fifty-five 

 specimens of the pulps obtained, both natural color and bleached.

Increasing the Durability of Fence Posts. By F. W. Besley. 

 Maryland State Board of Forestry, Baltimore, Md. 1912. Pp. 

 22. 



This bulletin deals with a number of experiments begun at 

 the Maryland Experiment Station to determine the efficiency of 

 various methods of preserving posts from decay. The first ex- 

 periments were made in 1888 and while the results are not con- 

 clusive they indicate (i) that applying a preservative with brush 

 is not very effective; (2) that creosote oil is more efficient as a 

 preservative than either coal tar or crude petroleum; (3) that 

 charring the portion of a post set in the ground affords little pro- 

 tection against decay; and (4) that filling in around a post with 

 stones or brickbats does not increase the durability of the post. 



A new series of experiments in cooperation with the U. S. 

 Forest Service was begun in the spring of 1909. Nearly 1,000 

 native grown posts of various sizes and species were used. Part 

 of these were treated with creosote, the others set untreated as a
