141. CuniTT, G. E. S. Wood in the Federated Malay States. SI p., 4 maps. Government 

 Press: Kuala Lumpur, 1920.- — The forests, their distribution, and, in the view of the author, 

 the great necessity of their conservation arc discussed. — /. //. Burkill.

 Plancher-les-Mines.] Bull. Trimest. .Soc. Forest. Franche-doint^ et lielfort 13: 2.j;i-2.")5. 

 1920. — This forest, 37 per cent fir, 17 per cent spruce, 34 i)cr cent hcech, and 12 per cent other 

 species, was managed until 1913 as a regular high forest with a rotation of 144 years. In 1913 

 steps were taken to convert it into a selection forest with the same rotation divided into 12 

 cycles of 12 years each. The annual yield is estimated at about 5 cubic meters per hectare. 

 Previous cuttings of beech have been too heavy, and an effort should be made to maintain 

 approximately the present proportion of this species. — S T. Dana. 



143. Demorlaine. Foret domaniale de Saint-Antoine. [State forest of Saint-Antoine.] 

 Bull. Trimest. Soc. Forest. Franche-Comt6 et Belfort 13: 255-258. 1920.— This, like most 

 State forests, is at a higher elevation and further from the center of population than the ad- 

 jacent communal forest. Composed of a mixed stand of broadleaf species and conifers, it is 

 divided into 7 series with a rotation of 128 years. Five of these are treated as regular high 

 forest, 1 as a protection forest, and 1 as an aesthetic forest. Silver fir reaches its optimum 

 development here at an altitude of rOO-1,200 m. and 1 specimen has a circumference of 4.4 m., 

 a height of 15 m. and a volume of 30 cubic m. Rather heavy cuttings were made during 

 the war, but these were handled so skillfully that the forest is in excellent condition. — 

 S. T. Dana.

Mi). DiHM. Ein Nachteil der Fichtenlohrindengewinnung. [A disadvantage of spruce 

 tanbark exploitation.] Forstwiss. Centralbl. 42: 399-401. 1920.^ — The shortage of tanning ma- 

 terials in Germany during and subsequent to the war was partly met by the use of spruce 

 bark. Trees cut during the w^inter must lie in the woods until May to be peeled, but this 

 results in very serious attacks by borers, which greatly reduce the value of the wood. It will 

 be necessary either to give up peeling winter-felled trees, or to find means to peel them earlier 

 so that the wood will become dry before the first beetle broods emerge in March. — W . A". 

 Sparhawk. 



147. Eberts. Ergebnis der Harznutzung in einigen Staatsforsten des Regierungsbezirks 

 Cassel im Jalir 1918. [Turpentining in state forests of Cassel in 1918.] Allg. Forst- u. Jagd- 

 zeitg. 95: 20S-212. 1919. — The result of harvesting turpentine from Scotch pine and Norway 

 spruce is presented. The expenditures and receipts are itemized. Scotch pine stands rang- 

 ing in age from GO to 105 years produced a net yield from turpentine of 210 marks per acre, and a net 

 profit of 1.75 marks per kg., while Norway spruce produced a net yield of only 1.40 marks per 

 acre and 0.12 marks per kg. The net return from collecting "wild" turpentine from Norway 

 spruce, that is, from trees barked by deer and other animals, was 0.49 mark per kg. The stud3' 

 showed that frequent scraping of the bleeding surface increases the total j-ield. The surface 

 should be scraped and sc:irred at least 5 times every 2 weeks, oftener if possible.— /ose/j/i S.

 [Identification of wood-destroying house beetle.] Zeitschr. Forst- u. Jagdw. 52 : 65-89. 1920. — 

 A description of the life history, food habits, and damage of the wood-destroying beetle, 

 Hylotrupes bajulus L. It attacks only coniferous wood and is common in building material. 

 The larvae, which live from 3 to 11 years, perforate the wood with numerous channels and 

 sometimes destroy it completely. — Joseph S. Illick.
