northern boundary of North Carolina and east of the Rocky Mountains. As a 

 further means of identification, brief descriptions of the fruits have also been 

 included. 



rorest conditions of the Ozark region of Missouri, S. J. Record (Missouri 

 Sta. Bui. 89, PI). 190-2S0, figs. 6, mai) 1). — This report was prepared by the 

 Forest Service of this Department in cooperation with the INIissouri Station 

 with the view of furnishing accurate information concerning the forest resources 

 of the Ozarlv region for use as a basis for future legislation, taxation, and 

 forest management and of making recommendations for inaugurating a new 

 state forestry policy. 



It contains a general discussion of the region relative to its physiography, 

 ownership of land, taxation, industries, and transportation facilities, forest 

 descrijjtions by counties and by types, second growth and reproduction, silvical 

 descriptions of the most important trees, damage to the forests by various 

 agencies, including destructive lumbering. Are, insects and diseases, wind, and 

 animals, information relative to the various timber and minor forest industries, 

 conclusions and recommendations, and a list of the trees and shrubs of the 

 Ozark region. A map locating the various forest types is appended. 



Breeding and use of tree crops, J. R. Smith {Amer. Breeders Mag., 1 

 (1910), No. 2, pp. S6-91). — ^A paper delivered before the American Breeders 

 Association in 1910 in which the author advocates the systematic breeding of 

 tree crops from the standpoint of forage for beast and food for man. Sug- 

 gestions relative to the improvement of various nut trees, mulberries, sugar 

 maples, persimmons, and foreign species, including basket wood, bush forage, 

 paper plants, etc. are given, together with remarks on the adjustment of tree 

 crops that have already been evolved. 



Breeding to improve physical qualities of timber, G. L. Clothier (Amer. 

 Breeders Mag., 1 (1910), No. 7/, />/). 261-263). — In this paper the author points 

 out a number of variations occurring in timber of the same species with the 

 view of stimulating foresters to systematic attempts at improving the physical 

 qualities of timber. 



The relative durability of post timbers, J. J. Crumley (Ohio Sta. Bui. 

 219, pp. 605-6JiO, figs. 18). — With the view of determining the relative durability 

 of different kinds of wood in contact with soil, an examination was made of 

 292 fences, containing 30,160 posts made out of the following kinds of wood : 

 Osage orange, locust, red cedar, mulberry, white cedar, catalpa, chestnut, oak, 

 honey locust, sassafras, and black ash. The fences examined were mostly in 

 Ohio but included a number in Indiana, Illinois, Kansas, and Texas to gain 

 information relative to the hardy catalpa and the Osage orange, which woods 

 have not been used long in Ohio. This bulletin describes the method of pro- 

 curing data, including the blank forms used, summarizes the data secured show- 

 ing the kind of timber from which the posts were made, the size of post, the 

 age or time of service, the number sound and rotten, and the percentage of 

 sound posts, and comments on a number of fences that have some point of 

 special interest. 



A table based on the data secured is given showing an estimate of the last- 

 ing quality of the different kinds of timber. In durability Osage orange ap- 

 pears to be far superior to the other woods. Yellow locust and red cedar come 

 next, followed by mulberry, white cedar, catalpa, chestnut, oak, and black ash. 

 As a rule the durability of honey locusts, sassafras, black walnut, white walnut, 

 and elm are poor. The results obtained in this study tend to show that the 

 durability of timbers such as the chestnut and the hardy catalpa have been 

 overestimated.
