738 EXPERIMENT STATION EECOKD. 



[Cacao experiments, 1913-14], J. de Verteuil {Bill. Dept. Agr. Trinidad 

 and Tobago, U {1915), No. 3, pp. 14-97, pis. 6).— A progress report for the year 

 ended August 31, 1914, relative to manurial, shade, pruning, and natural yield 

 experiments being conducted in a number of plantations in Trinidad (E. S. R., 

 30, p. 444), including also data on manurial experiments with cacao and rubber 

 in Tobago. 



The flower garden, T. W. Sandeks (London: W. H. d L. ColUngridge [1915], 

 2. ed., pp. 472, pis. 56, figs. 40). — ^A revised and enlarged edition of the author's 

 work which treats of the designing, formation, planting, and management of 

 flower gardens, including the description and cultivation of all hardy and half 

 hardy plants, trees, and shrubs adapted for outdoor culture in the British Isles. 



FORESTRY. 



Forest administration in the southern Appalachians, K. W. Woodwabd 

 {Proc. Soc. Amer. Foresters, 10 (1915), No. 2, pp. 130-140). — A discussion of 

 forest conditions in the southern Appalachians with special reference to modifi- 

 cations which will be necessary in order to make the forest policy which has 

 been worked out for western conditions fit in the East. 



Present condition of applied forestry in Canada, H. R. MacMillan (Proc. 

 Soc. Amer. Foresters, 10 (1915), No. 2, pp. 115-129). — A review of forest 

 activities and conditions in Canada with special reference to the work of 

 administration, protection, reforestation, and other activities leading to forest 

 conservation. 



Sand dune reclamation on the coast of northern California and southern 

 Oregon, F. B. Kellogg (Proc. Soc. Amer. Foresters, 10 (1915), No. 1, pp. 41-^4^ 

 figs. 2). — An account of methods employed in sand dune reclamation as carried 

 out on an extensive scale for over 15 years near the Oregon line in California, 

 with special reference to the application of the methods in similar sand dune 

 areas situated on the Siuslaw National Forest, Oregon. 



Notes on the relation of planting methods to survival, E. E. Carter (Proc. 

 Soc. Amer. Foresters, 10 (1915), No. 1, pp. 9-17). — The author here presents the 

 results of a study of planting methods started in 1913 on the Harvard Forest, 

 Petersham, Mass. The three methods employed consisted in brief of planting in 

 a mattock hole, planting in a slit with the sod previously removed, and planting 

 in a slit without removing the sod. 



The experiment has not been conducted sufficiently long to arrive at any con- 

 clusion. The data thus far secured, however, show that the hardier species as 

 a group are less affected by the different methods of planting than the more 

 tender species. 



A formula for normal growing stock in selection system forests, T. T. 

 Munger (Proc. Soc. Amer. Foresters, 10 (1915), No. 1, pp. 18-21, figs. 2). — The 

 author here presents a formula which is believed to be thoroughly applicable in 

 preparing preliminary working plans for virgin forests where adequate yield 

 tables can not be prepared. 



A possible measure of light requirements of trees, W. W. Ashe (Proc. Soc. 

 Amer. Foresters, 10 (1915), No. 2, pp. 199, 200). — The author is of the opinion 

 that the relation between the cambium surface of the stem and the surface of 

 the crown of dominant trees affords a reliable basis for measuring the light 

 requirements of trees. By establishing this ratio between cambium surface and 

 surface of the crown in stands at different ages and on different quality sites, 

 either for the dominant trees or for the crown classes which receive direct light, 

 series are obtained which, it is believed, should express the relative demands 

 on light for a species at different ages.
