842 EXPERIMENT STATION RECORD. 



The results show that for each species of wood a formula should be deter- 

 mined which will show the length of time the ix»sts should be heated in hot 

 creosote and cooled in cold creosote to obtain the degree of penetration desired. 



Preliminary report on forestry investigation at Colesborne, Gloucester- 

 shire, H. A. Pritchard, R. G. Stapleton, and M. Kershaw {Ann. Sci. Bui. 

 Roy. Agr. Col. Cirencester, 1910, A'o. 2, pp. 47-S8, pis. 3, fig. 1). — The investiga- 

 tion in question is being conducted by the Roynl Agricultural College, Ciren- 

 cester, to determine the causes of the extreme differences in the development of 

 different species and even in the same species in a plantation on thin, poor, 

 calcareous soils. The plantation is described and the experiments being con- 

 ducted are outlined. They are to include studies of the action of various con- 

 ditions of soil and climate, as well as such indirect agencies as aspect and 

 contour on tree development.

 of Bengal for the year 1909-10, F. Trafford {Ann. Rpt. Forest Admin. Lower

The forest re-formation and private ownership: A historical study, com- 

 parative law, new projects, L. Ducrot {La Reforme Forestidre et la Propri6t4 

 Priv6e. Etude Historiqve-Droit Compare, Projets Nouveaux. Lyon, 1910, pp. 

 TII+335). — In view of the growing interest relative to the administration, con- 

 servation, and extension of forest lands, the author has aimed to bring together 

 the important literature on the subject having special bearing on French condi- 

 tions. 



Part 1 contains a historical sketch and analysis of French legislation from 

 ancient times up to the present in its relation to private ownership. Part 2 

 contains a critical study of the forest laws of Italy. In part 3 the question of 

 forest re-formation is presented, both from the standpoint of the Government 

 and of the private invidiual, including various projects proposed for solving this 

 question. 



A bibliography on the subject is included. 



Example of a German working plan, trans, by A. B. Recknagel {Forestry 

 Quart., 9 {1911), No. 3, pp. 391-399). — This* comprises a summary of the meth- 

 ods of management which form a part of the Working Plan for the Tegernsee 

 Forest in Bavaria, the manuscript of which is in possession of the Yale Forest 

 School. The plan deals with a practically virgin forest of spruce with flr and 

 beech in mixture, and it is suggested that it will be particularly applicable to 

 similar conditions in America. 



The need of a vigorous policy of encouraging cutting on the National 

 Forests of the Pacific coast, B. P. Kirkland {Forestry Quart., 9 {1911), No. 

 3, pp. 375-390). — After analyzing the conditions and factors involved in the 

 development of methods of cutting and regeneration in the National Forests 

 of the Pacific coast, the author concludes in part that present cutting based 

 on a sustained annual yield can, without any damage to the future, yield liberal 

 revenues to federal and state governments and that all possible present 

 revenue within a sustained annual yield basis, which is not taken, will be 

 irrevocably lost. The forests, it appears, are covered for the most part with
