tical trial of the results of research. It is also proposed to establish chairs of forestry at the 

 University of Jena, for training of forest officers, and to found a forest and game museum. —

 Kiefernharznutzung. (Biological basis of resin production from Scotch pine.) Julius 

 Springer: Berlin, 1919.] Forstwiss. Centralbl. 42:157-159. 1920.— The German turpentine 

 industry, which only began in 1915, has in four years developed into an important industry; 

 and the improved methods devised as the result of intensive research have increased pro- 

 duction very greatly over the cruder methods formerly used in Austria and even over the 

 French and American methods. Strict application of all that has been learned will result 

 in a yield of resin four times as great as that obtained by the methods used in 1915. Munch's 

 book covers the ground very thoroughly, both from scientific and practical points of view. —

 [Silvicultural excursion in the home of the Langenbrand wedge-shelterwood cutting.] Forst- 

 wiss. Centralbl. 42 : 233-237. 1920. — The author describes the silvicultural system used by 

 De. Eberhard in the Langenbrand forest (Wurttemberg). This consists of a preparatory 

 stage, in which the stand is prepared for reproduction by repeated moderate thinnings, 

 and a stage of removal cuttings beginning about 5 years after reproduction is established. 

 The preparatory cuttings are intended primarily to get rid of raw humus, which may also be 

 removed by hand either over the whole area or in seed-spots. These cuttings also make room 

 for reproduction, especially of tolerant species, to start. The removal cuttings are rather 

 light, and repeated every year if practicable. They begin in the interior of the stand and 

 progress outward, beginning with small openings, which are gradually enlarged into a wedge 

 shape with the point toward the wind. The shape of opening is not definite, but may be 

 varied to suit local conditions. Damage from storms and logging is reduced to a minimum, 

 and natural reproduction is very successful. Of the whole area, 92 per cent has been repro- 

 duced naturally. The principal characteristic which distinguishes this from certain other 

 methods is the shape and arrangement of the cuttings so as to eliminate damage from logging 

 and from winds. — W. N. Sparhawk. 



120. Farrington, H. A. Annual progress report on forest administration in the presi- 

 dency of Bengal for 1918-19. 51 p. Calcutta, 1920. — The usual annual report dealing with 

 forest operations in the province. It is reported that 16 per cent of the reserved forests and 

 3 per cent of the protected forests were open to grazing, and that the entire area of the 

 unclassed forest is always open for this purpose. Unrestricted grazing and lack of fire pro- 

 tection caused the Muli bamboo to fail in re-establishing itself properly after seeding. Wher- 

 ever cattle have access (practically on all areas within a mile of the forest boundary) seedling 

 regeneration of most kinds of trees is destroyed. It is necessary to fence planted areas to 

 protect them from damage by cattle grazing. In the unfenced hills natural regeneration is 

 entirely destroyed by cattle. Above 5,500 feet in altitude natural reproduction in coppice 

 fellings is not successful and must be supplemented by planting. At lower elevations the 

 coppice system produces excellent results. Burned areas in coppice cuttings give success 

 with a large number of species, including seedlings of Mallata, Toon, and other species. 

 Experiments were undertaken with growing blue gum {Eucalyptus globulus) for fuel purposes. 

 At the close of the year there were 50 forest villages, totaling an area of 7508 acres. The 

 surplus at the close of the year was 1,121,760 Rs. Twenty-one form tables and a map of the 

 province are appended. In chapter seven is given a review of forest administration in Bengal 

 for the preceding 5-year period. — E. R. Hodson.
