 — A note on the growing of various species of acacia and the products of the destructive dis- 

 tillation of black wattle wood. — C. F. Korstian.

 Agric. Com. y Trab. 2: 493-497. 3 fig. 1919. — In this article attention is called to the tree 

 Ochroma lagopus Sw. as a native tree valuable for planting because of the lightness of its 

 wood, its rapid growth, medicinal properties and the wool or fiber in its fruits. — F. M. Blodgett. 



153. Badotjx, H. Die Waldreservationen in der Schweiz. [Forest reserves in Switzer- 

 land.] Schweiz. Zeitsch. Forstwesen 71: 2-4. 1920. — The policy for acquiring national for- 

 ests was approved in 1906, and in 1910 three forest reserves were approved involving a total 

 area of about 50 hectares. These areas were in effect leased by the government for periods 

 of 25 and 60 years. The policy of the continuation of the forests was left to be determined 

 when the period of lease expires. Some areas were paid up for the entire term, and others are 

 paid by annual installments. — J. V. Hofmann.

 1919. — Coppice overtops planted stock after cuttings in sal forests. To prevent this planting 

 is now made about five years in advance of the opening of the stand giving the planted stock 

 an opportunity to develop and become dominant at the start. — E. N. Munns. 



155. Barbey, A. Les forests Suisse pendant la guerre. [The Sv/iss forests during the 

 war.] Bull. Trimest. Soc. Forest. Franche-Comte et Belfort 13: 46-51. 1919. — Administra- 

 tion of the 982,000 hectares of forest lands in Switzerland, one-fourth of the total area of the 

 country, is decentralized. Cantonal forests comprise 4 per cent of the forest area, communal 

 forests 67 per cent, and private forests 29 per cent. There are no national forests, and the 

 national forest service employs only 17 professional foresters. It contributes, however, to 

 the salaries of the cantonal forest officers; supervises the use made of subsidies granted to the 

 cantons; administers the federal forest law; provides technical instruction at the forest school 

 at Zurich; and directs the forest experiment station. — At the outbreak of the war construction 

 was automatically arrested and cutting materially decreased. After ten or twelve months, 

 however, the foreign demand for timber and the native demand for wood fuel (due to the 

 scarcity of coal), resulted in a steadily increasing cut. In 1916 wood exports, which before the 

 war had been from 40,000,000 to 50,000,000 francs a year less than wood imports, exceeded the 

 latter by 68,000,000 francs. The increased cut was accompanied by increased prices, fuel 

 doubling and timber trebling in value in three years or less. Little or no overcutting took 

 place in the public forests, but was more or less marked in the private forests, where advant- 

 age was taken of the extraordinary demand to improve the stands by the removal of many 

 old reserves which before the war could not be marketed profitably. Strict supervision was 

 exercised over all cuttings, a federal decree in 1917 requiring a permit for all cuttings of 20 

 cubic meters or more and fixing a fine of from 10 to 40 francs per cubic meter for all cuttings 

 made without a permit. Moreover, measures were taken to maintain and if possible to in- 

 crease the future productivity of the forest. For instance, in the Canton of Vaud, the number 

 of inspectors was increased so that the average area under the supervision of each was reduced 

 from 7,300 to 4,000 hectares. This example should be followed by other cantons as a means 

 of increasing production and of rendering Switzerland independent of foreign supplies. An 

 increase of only 1.1 cubic meters per hectare in the annual growth of the 600,000 hectares of 

 communal forests would be sufficient to wipe out the present deficit of 700,000 cubic meters, 

 but this can hardly be expected as long as the average area under the supervision of a technical 

 forester remains as high as 8,570 hectares. — S. T. Dana.
