Note on Terminalia chebula and its fruit, the myrabolam of commerce, 

 J. E. C. Turner {Indian Forester, 33 (JDOl), No. 8, pp. 302-365).— A description 

 is given of the tree and fruit, together with an account of its range and distribu- 

 tion, and the methods of harvesting and preparing the fruit for market. After 

 being prepared, the fruit of the chebula, which is the myrabolam of commerce, 

 is shipped to Europe for dyeing and tanning purposes. 



Forest tables: Lodgepole pine, E. A. Ziegler (U. 8. Dept. Agr., Forest Serv. 

 Cire. 126, pp. 2Ii). — In the course of general investigations considerable data have 

 been gathered by the Forest Service relative to tree growth, form, and volume. In 

 this circular measurements of lodgepole pine made by field parties in Wyoming 

 in 1901 and 1905, and in Montana in 1902, are compiled and presented in tabular 

 form. While they represent the results of many investigations, they are offered 

 principally as suggestions for further investigations rather than as final. The 

 various subjects considered are stand tables by well-recognized types and locali- 

 ties, reproduction tables, height and diameter growths, volume by feet and prod- 

 ucts, taper measurements, and present and potential yields. 



Form, and content of the white pine, A. Schiffel {Mitt. Forstl. Versuchsw. 

 Osterr., 1907, No. 32, pp. 89). — This work consists of reference tables for com- 

 puting the form and content of white pine, including form factor and form 

 quotient tables, form and volume tables, and tables for computing volume and 

 sorting wood having a diameter of over 7 cm. (about 2,8 in.) at the smaller end. 

 The investigations upon which the tables are based, together with other neces- 

 sary explanations, are given in the text. 



A study of the botanical and physiolog'ical variations of Hevea brasilien- 

 sis with reference to selection, (J. Vernet {Jour. Agr. Trap.. 8 {1907), No. 73, 

 pp. 195-203, fig. 1). — The author discusses the variability of this species of rub- 

 ber, both with regard to its botanical features and also as to the composition of 

 its latex and. the yield from individual trees of commei-cial I'ubber. Tabular 

 data are given from observations made on a large number of trees with regard 

 to their yield in latex and rubber, and the author emphasizes the importance of 

 a systematic study of the individual trees with a view to selecting seed for 

 propagation from those which give the best returns. 



Manag'enient of second growth in the southern Appalachians, R. Zon ( U. S. 

 Dept. Agr., Forest Serv. Cire. 118. pp. 22). — From SO to 85 per cent of the total 

 wooded area of the southern Appalachians is said to be second growth, a large 

 pi'oportion of which consists of even-aged stands, the results of cuttings either 

 for charcoal or, moi'e recently, for ties and mine timbers. This circular con- 

 tains suggestions for the management of such even-aged stands for their best 

 development for the future wood supply. The chief phases con,sidered are econ- 

 omy in utilization, waste in cutting mine timber, betterment of methods of 

 logging and lumbering, management of sprout forests, and protection from fire 

 and other losses. 



Considerable tabulated data are given showing the comparative waste in the 

 production of cross-ties iinder the present system and the possible yields under 

 more economical methods, as well as tables showing the height and diameter 

 growth and sprouting vigor of different species of oak found in different types 

 of forests. The effect of fire upon height growth of sprouts is also shown, as 

 well as estimated yields of lumber, wood, and ties of second growth hardwoods 

 in the Appalachian range. 



Accretion investigations with firs. Usener {AUg. Forst. u, Jagd Ztg., 83 

 (1907), Sept., pp. 305-310). — In connection with the development of working 

 plans in the State forests of Alsace-Lorraine data were collected with regnrd to 

 the age and growth accretion of several thousand firs, including a counting of 

 the annual rings both at the- large aud small end of the trees, and height and
