coming up to gray birch, pitch pine, and juniper. The advantages of thinning are 

 pointed out and records given of the productiveness of different small areas. 



Under the provisions of a late law about 1,000 acres of sprout land has been pur- 

 chased by the forester of the State at a cost of $1.63 per acre, upon which experi- 

 ments in planting, thinning, etc.. will be carried out,

 The text of the recent law passed in Connecticut with reference to fire wardens and 

 the protection of forests from tire is given. 



Notes on the flora, especially the forest flora, of the Bitter Root Moun- 

 tains, L. H. Pammel (Proc. Iowa Acad. Sri., 12 (1.904), pp. 87-100, ph. 6). — An 

 account of the survey of that part of the Bitter Root Mountains west and south of 

 Hamilton, containing considerable data relative to the proportions of the different 

 species of coniferous trees and their rates of annual growth at different altitudes and 

 in different years. Mention is also made of introduced and weedy plants in that 

 section of the country. 



Forest management in Bavaria and Saxony, C. S. Orwin (Jour. Southeast. 

 Agr. Col. Wye, 1905, No. 14, pp. 249-261). — The author reports upon a tour of inspec- 

 tion of the oak and beech w r oods of the Spessart district of Bavaria, the pine woods 

 of Bamberg in Bavaria, and the spruce woods of Saxony, describing the objects of 

 management in each case, methods of regeneration, etc. 



The leaf-shedding disease ( Hysterium pinastri ) is stated as one of the worst scourges 

 of the pine. It has been controlled by spraying with Bordeaux mixture. The 

 spraying is done once a year in July or August for 4 or 5 years. 



Reports on forest administration in Burma for the year 1903-4, J. Cope- 

 land et al. (Rpts. Forest Admin. Burma, 1903-4, pp. 189) . — An accountof the extent 

 and character of the State forests and their management as regards working plans, 

 protection, sylviculture, and exploitation, with a financial statement as to receipts 

 and expenditures. 



During the year tapping experiments were performed on Chavanessia creepers. 

 The quantity of rubber yielded by this plant did not pay for the cost of extraction. 

 AVhen the plant was cut down to the root and then chopped into small pieces no 

 better results were obtained. 



The experimental garden in the Tenasserim Circle contains 79.5 acres of Hevea 

 rubber trees planted in 1878-9. 



A series of systematic tapping experiments was carried out with these trees with 

 the following results: Trees 2 to 4 ft. in girth yielded an average of 4.4 oz. of rubber 

 per tree; 4 to 5 ft., 7 oz.; 5 ft. and over, 16 oz. The latex of the older trees was 

 much richer in rubber than the younger trees. Thus, 100 cc. of latex from trees 2 

 to 3 ft. in girth yielded 1.38 oz. of rubber. From trees 3 to 4 ft. in girth the yield 

 was 1.73 oz.; from trees 4 to 5 ft. in girth, 2.26 oz.; and from trees 5 ft. and over, 

 2.94 oz. 



The experiments indicated that a man could tap from 10 to 20 trees a day, accord- 

 ing to their girth, and could collect on an average 550 cc. of latex, representing 6.6 

 oz. of dry rubber. 



Administration report of the forest department in the Bombay Presi-
