551. Fisher, 11. T., and E. I. Terry. Management of second growth white pine in cen- 

 tral New England. Jour. Forestry 18: .V>s 366. L920. -Studies show that the shelterwood 

 system is host adapted for white pine second growth in pun; stands, using a combination of 

 thinning with clear cutting. Reproduction is thus assured though there has been much 

 trouble with snout beetles in seedlings and the pine weevil in saplings. Slash may be left on 

 the ground in the mixed hardwood and pine stands 1 ml must be removed in pure pine stands 

 as it wastes much space and precludes reproduction. — E. N. Munns. 



552. FlTZWATBB, J. A. Discussion of the Pinchot Committee report. Jour. Forestry 18: 

 KV1 -lf>i). 1920. — -Forest devastation in the Inland Empire (Northwest U. S. A.) has not been 

 as severe as it has been depicted but there is need for a forest program handled by the Federal 

 government rather than by the individual states. Acquisition of cut-over lands by the 

 government is favored and the cost of conservative logging and mature timber should be 

 borne by the public. — E. N. Munns.

554. Green, Frederick J. Germinative capacity of pine seed. Quart. Jour. Forest 14: 

 140-141. 1920. — Scotch pine seed collected from trees of several ages was left exposed to the 

 heat of an unused hothouse for one summer. It was sown the following spring and gave the 

 following germination results: Seed from 15-year old trees, 87 per cent; from 30-year old trees, 

 50 per cent ; from 45-year old trees, 30 per cent; from 60-year old trees, 15 per cent; from 110- 

 year old trees, failure. These results agree with those discussed in another article, Ibid., 

 January, 1910. — C. R. Tillotson. 



555. Greenfield, W. P. The beech in Lincolnshire. Quart. Jour. Forest. 13: 269-271. 

 1919. — -This is a short discussion dealing with the lack of beech reproduction on the chalk 

 Wolds of Lincolnshire, where there are many good beech woods but no natural beech regen- 

 eration. The author raises the question as to reasons for this, but does not answer it. — C. R. 

 Tillotson. 



556. Grieve, J. W. A. The self-contained forest estate in the Himalayas. Indian Forester 

 46: 273-279. 1920. — Each forest unit should become as self sustaining as possible, the unit 

 to be the forest community. Forest and field crops may be grown simultaneously, and a 

 group of skilled forest workmen evolved. — E. N. Munns.

558. Hagem, Oscar. Svensk froundersogelser. [Seed-testing in Sweden.) Tidsskr. 

 Skogbruk 28: 72-80. 1920. [A review of the report published by Edward Wiebeck .] — Both 

 Wiebeck and the author found appreciable differences in the quality of Scotch pine and Nor- 

 way spruce seed, the better seed coming from the warmer parts of these two countries. 

 Wiebeck's investigations show that, for northern Sweden, 50 per cent or higher germination 

 was obtained from seed collected where the isotherm for June to August was between 13 and 

 14°C.; the medium quality of seed, which germinated from 41 to 50 per cent, was collected 

 where the isotherm for the same months was from 12 to 13°C. ; and the poorer kind, which ger- 

 minated only 40 per cent or less, was collected where the isotherm showed below 12°C. Hag- 

 em's results correspond quite generally with these, there being a discrepancy of only 0.5°C.
