1841. Beeson, C. F. C. Food plants of Indian forest insects, Part V. Indian Forester 

 47: 21-25. 1921. — A continuation of previous work, the present compilation listing 25 insects 

 which feed upon a variety of forest trees and shrubs.- — E. N . Munns. 



1842. Beeson, C. F. C. Hoplocerambyx and the dying off of sal. Indian Forester 47: 

 68-77. 1 fig. 1921. — A marked parallelism exists between the number of dead trees per year 

 and the annual amount of rainfall; in abnormally wet years the number of sal dying is greatly 

 increased, in abnormally dry years the number is very markedly decreased. The emergence 

 period of the sal borer {H. spinicornis) is directly influenced by the initial date and extent 

 of the rains through their effect on the moisture content of the heartwood of the sal and the 

 relative humidity of the pupal chamber. In a wet year 75 per cent of the beetles emerge 

 in the 1st month of the rains; in a dry year the period is prolonged nearly 2 months. The 

 wet year increases the damage to sal by bad aeration through a rise in the water table, espe- 

 cially on heavier soils. This weakening renders the tree much more susceptible to the borer 

 attacks, the borer acting as a secondary factor. — Control measures during an epidemic call 

 for the removal from the forest before the end of April of all attacked parts of trees down to 

 18 inches girth in normal years and the removal of all parts of trees dov/n to 12 inches girth 

 in years of early and abundant precipitation. Removal of dead and dying trees on which 

 the foliage is turning brown and trees with green foliage but with an abundant ejection of 

 wood dust is indicated. — E. N . Munns. 



1843. Bennett, H. C. Experiments in sowing seeds of Cassia auriculata at Golla, 

 Anantapur. Indian Forester 47: 25-29. 1921. — Six methods of seed sowing have been tried, 

 each on 5 acres. Sowing in furrows gives the cheapest successful result, but plowing, hoeing, 

 and harrowing give the best results.' — E. N. Munns. 



1844. Brown, N. C. Vallombrosa forest in Italy. Amer. Forestry 26: 647-654. 15 fig. 

 1920. — The forest consists of 3500 acres, 875 acres chestnut and 125 acres containing 3 varieties 

 of Italian pines. The remainder is made up of European beech (Fagus sylvatica) and silver 

 fir {Abies peciinata). The forest has been under continuous management by Italian forestry 

 officials since 1869, and for centuries before that date by the monks.— Chas. H. Otis.

1846. Chaytor, a. H. Planting Douglas fir and Sitka spruce in cleared coppice. Quart. 

 Jour. Forest. 14: 161-164. 1920. — Plantations of Douglas fir, Sitka spruce, and Japanese 

 larch set out in old coppice woods at Iridge Place, Hurst Green, Sussex, England, from the 

 years 1910 to 1913, were tended very carefully previous to the war, the rubbish and coppice
