 Comm. Conserv. Canada, 1918, pp. VIII+409, pis. 49). — A report on a survey of 

 the forest resources of British Columliia, conducted under the direction of 

 the Commission of Conservation of Canada. Part 1 discusses geographical 

 relations, physiographic relations, climatic and soil relations, land tenure in 

 British Columbia, forest administration on provincial lands, forest adminis- 

 tration on Dominion lands, forest policy, forest exploitation, forest trees in 

 British Columbia, and insect injuries to forests in British Columbia. Part 2 

 contains summarized data on the foi-est resources of British Columbia as a 

 whole and detailed data on the forest resources of the several interior regions 

 and the coastal belt of the Province. The test is accompanied by numerous 

 Illustrations and maps. Appended to the report are the timber-sale contract, 

 volume tables for Douglas fir, cedar, and hemlock, and the British Columbia

Reafforestation and the economic developm^ent of France, P. Descombes 

 {M6m. Soc. Sci. Phys. ct N'at. Bordeaux, 7. sei:, 2 {1918), pp. 103-217, pi. 1, ftq^. 

 2). — A memoir on previous reafforestation policies in France, with a plea for a 

 much broader development of both national and private reafforestation. 



In part 1 the author discusses the denudation and decadence of the moun- 

 tain regions, the overgrazing of pastures, and the genesis of the laws on the 

 reafforestation of mountains. Part 2 deals with the forests of the plains, the 

 forestry situation at the beginning of the nineteenth century, and the large 

 public reafforestation projects undertaken during the nineteenth century. 



Previous to the world war, the author concludes, France did not produce 

 half of the construction wood needed for home consumption. He points out 

 the importance of reafforestation to the economic development of the country, 

 and suggests remedies with the view of stimulating private, as well as national, 

 silviculture. 



A forest policy for Australia, C. E. Lane-Poole {Sci. and Indus. [Aust.l, t 

 {1919), Nos. 2, pp. 87-93, figs. 6; 3, pp. 152-161, flgs. 70).— The author sketches 

 the conditions that liave brought about a serious forestry situation in Australia, 

 recommends the adoption of a uniform forest policy for the whole country, and 

 considers the essential features of such a policy. 



Effect of chang'ed conditions upon forestry, W. W. Ashe {Jour. Forestry, 17 

 {1919), No. 6. pp. 657-662) .—The author points out that in view of the increase 

 in stumpage value of low-grade timber in the Appalachians clean cutting is no 

 longer necessary to secure an ample margin of profit. Low-grade trees may be 

 reserved for price appieciation, small trees for accretion, and trees of the 

 choicest species for seed trees. The motor truck and the portable band-mill 

 have been used with sufficient success to indicate that, with a good system of 

 roads, cuttings may be made over the same tract at frequent intervals without 

 materhilly added cost. The conduct of investigations in serial fellings on pri- 

 vate lands with auto trucks as motive power is advocated.
