Bulletin 64: Loblolly Pine in Eastern Texas. 



A careful study of one of the valuable southern pines, especially in relation to its 

 use for tie timbers. The investigation was limited to eastern Texas, but many of 

 the facts and conclusions may be applied to wider areas. The tree is common in 

 most parts of the South, and grows vigorously on abandoned fields. 



Bulletin 69: Sugar Pine and Western Yellow Pine in California. 



A study of the range, distribution, silvical and silvicultural characteristics, com- 

 mercial value, and treatment under forest management of two of the most important 

 and valuable commercial trees of California. Its conclusions are that conservative 

 management of sugar pine and yellow pine is practicable; that fire, the greatest 

 obstacle to securing future crops, can be prevented at reasonable cost; and that 

 under effective protection, and with a sufficient number of seed trees left in lumber- 

 ing, natural reproduction will perpetuate the forest. 



FOREST STUDIES. 



Bulletin 47: Forest Resources of Texas. 



A comprehensive study of the forests of Texas, their extent, composition, and 

 economic importance. The types of forest characteristic of different regions are 

 described, their relation to physiography and climate is considered, and suggestions 

 toward a wise State policy are discussed. 



Bulletin 48: The Forests of the Hawaiian Islands. 



A study made at the request of the Hawaiian Board of Commissioners of Agricul- 

 ture and Forestry. The report outlines a forest policy for the islands, which has 

 been adopted and put into effect. 



Bulletin 49: The Timber of the Edwards Plateau of Texas. 



A study of the character and distribution of the forest in the region named. It 

 shows distinctly the importance of utilizing to the fullest extent the limited timber 



supplies of the region. 



Bulletin 55 : Forest Conditions of Northern New Hampshire. 



A study made in cooperation with the State of New Hampshire, which appropri- 

 ated $5,000 for the purpose. A study of forest conditions in southern New Hamp- 

 shire, now in progress, vv'ill complete the work. 



Bulletin 66: Forest Belts of Western Kansas and Nebraska. 



This report deals with forest conditions in the western portions of Kansas and 

 Nebraska. It includes a comprehensive study of the present forest growth of the 

 region and of the factors which tend to prevent its increase The conclusion reached 

 is that the present forests are much more restricted in area and are poorer in char- 

 acter than they need be, and practical suggestions are given for their extension. 



FOREST BOTAJVICAL AND DENDROLOGICAJL STUDIES. 



* Bulletin 17: Check List of the Forest Trees of the United States. Price, 15 cents. 



Giving the common and scientific names of each species, together with their geo- 

 graphical distribution. 



* Bulletin 28: A Short Account of the Big Trees of California. Price, 10 cents. 



An account of the location and character of the Big Tree groves. The possibility 

 of maintaining them through forest protection is pointed out.
