 of forest industry practicable?) Forstwiss. Centralbl. 41: 210-226. 1919.— Most socialists 

 agree that forest industries of Germany should be socialized, in order to avoid danger of mon- 

 opoly, to insure continuity of employment and of supplies of forest products, and to insure 

 maximum sustained production at lowest cost. Methods suggested are State ownership, 

 either by purchase or confiscation, syndicalization, or division of large holdings. State owner- 

 ship is unnecessary because the State already owns a sufficient proportion of the forests to 

 prevent monopoly, and undesirable because of the probable decrease in efficiency due to bu- 

 reaucratic inertia and political influences. Moreover, it is financially impossible. Syndicali- 

 zation is not desirable because the nature of the business is not adapted to this form of manage- 

 ment. Division of holdings is contrary to the requirements of efficient forest production, and 

 unnecessary anyway because there are few very large holdings. The best way for a demo- 

 cratic state to control forest production is by use of its powers of taxation. The forest law 

 should require that all forest tracts of more than 100 hectares be managed according to a 

 working plan, under technical supervision. Beyond this, the owner should have entire 

 freedom of action. Owners of smaller tracts should form cooperative bodies or looser asso- 

 ciations, in order to be able to take steps toward more efficient management. The State 

 should supervise the activities of these associations. — W. N. Sparhawk.

 Eaux et For£ts 57 : 213-228. 1 fig. 1919. — The critical situation in which Great Britain found 

 itself during the war as a result of totally inadequate native wood supplies has led to the for- 

 mulation by a specially appointed committee of a comprehensive forestation program, in- 

 tended to decrease materially Great Britain's present dependence on other countries and to 

 provide a reserve capable, in case of war, of meeting for three years all its needs for wood at 

 a rate of cutting five times as great as the normal annual consumption. The program contem- 

 plates the establishment in 80 years of 717,000 hectares of coniferous plantations, chiefly 

 Scotch pine, European larch, Douglas fir, Sitka Spruce, Norway Spruce, and western red 

 cedar. Two-thirds of this area, or 478,000 hectares, will be forested during the first 40 years, 

 and 101,000 hectares during the first ten years. Of this latter area, the state will itself acquire, 

 either by purchase or lease, and plant 60,000 hectares; it will associate itself with communi- 

 ties and individuals in the cooperative planting and management of 10,000 hectares; and 

 through the granting of subsidies of one kind or another it will encourage the forestation of 

 10,000 hectares by communities and individuals. The remaining 21,000 hectares are to be 

 secured through the voluntary or forced reforestation by their owners of areas cut clear during 

 the war. In addition the reforestation during this period of 4,000 hectares of hardwoods 

 (and eventually of 8,000 hectares) is contemplated. The committee proposes certain reduc- 

 tions in forest taxes and in freight rates for forest products, the systematic training of both
