and methods obtaining in the industry. Detailed statistics are also given of 

 teak wood exports from Siam and Indo-China. 



Annual report on the forest administration in Ajmer-Merwara for the year 

 1913-14, H. Chand {Ann. Rpt. Forest Admin. Ajmer-Merwara, 1913-14, pp. 

 6+32). — This comprises the usual progress report on the administration and 

 management of the state forests of Ajmer-Merwara. Data relative to forest 

 areas, forest surveys, working plans, silvicultural operations, yields, revenues, 

 expenditures, etc., are appended in tabular form. 



The need of working plans on National Forests and the policies which, 

 should be embodied in them, B. P. Kirkland (rroc. Soc. Aincr. Foresters, 10 

 (1915), No. 4, pp. 341-370). — This article comprises as a whole a plea for cer- 

 tain changes in the National Forest policy in dealing with the timber resources 

 on the National Forests. The author first considers the desirability of working 

 plans and then discu.sses a number of fundamental policies \\'hich, in his 

 opinion, should be provided for in working plans. 



Regional forest plans, D. T. Mason (Froc. Soc. Amcr. Foresters, 10 (1915), 

 No. 4^ PP- 31i 1-375). — In this article the author advocates the preparation of 

 working plans for forest regions rather than for individual National Foi'ests 

 within a given forest region. 



Working plans, H. H. Chapman (Proc. Soc. Anier. Foresters, 10 (1915), No. 

 4, pp. 376-382). — A discussion of forest working plans with special reference to 

 their application on the National Forests, 



Some notes on forest ecology and its problems, R. H. Boeeker (Proc. Soc. 

 Amcr. Foresters, 10 (1915), No. 4, pp. 405-422). — This paper comprises as a 

 whole a discussion of the methods, scope, and importance of forest ecology, 

 together with a classification and summary of its problems. 



Light burning at Castle Rock, S. B. Show (Proc. Soc. Amer. Foresters, 10 

 (1915), No. 4. pp. 426-433). — In order to secure reliable data on the harmful 

 or beneficial effects of light burning on forest growth, experiments were started 

 at Castle Rock, Cal., in the spring of 1911. The timber in the experimental 

 area consisted of yellow pine, with a slight admixture of sugar pine, Douglas 

 fir, incense cedar, and California black oak. From the data secured it is con- 

 cluded that light burning is a failure as a fire-protective measure, and that 

 the damage to reproduction is so great that the practice of light burning is 

 precluded where the establishment of young growth is desired. 



Brush disposal in lodgepole-pine cuttings, D. T. Mason (Proc. Soc. Amer. 

 Foresters, 10 (1915), No. 4, PP- 399-404, fig- 1)- — The author presents some evi- 

 dence to show that the piling and burning of brush for the purpose of protect- 

 ing forest areas from fire may be unnecessary and unprofitable where grazing 

 is feasible. A diagram is given of a proposed experiment which it is planned 

 to conduct to determine much more accurately the interrelations of brush 

 disposal, fire hazard, grazing, and reproduction. 



A new aspect of brush disposal in Arizona and New Mexico, W. H. Long 

 (Proc. Soc. Amer. Foresters, 10 (1915), No. 4, pp. 383-398) .—This article deals 

 specifically with the rapidity with which brush rots and with the fungi causing 

 this rotting under different methods of disposal. The three methods of dis- 

 posal considered are piling, scattering, and merely pulling the brush out of 

 the way of reproduction. 



Uniformity in the forest fire legislation affecting railroad operation and 

 lumbering, P. T. Coolidge (Proc. Soc. Amer. Foresters, 10 (1915), No. 4, PP- 434- 

 4-52). — In this article the author describes the legislation enacted in different 

 States with special reference to certain characteristics which render it effective 

 or otherwise.
