species. The rapid-growing kinds, however, in the mixed plantations are growing 

 so fast as to overshadow some of the more valuable trees, and those which can not 

 endure shade are being killed. Such trees as ash, butternut, black walnut, and elm, 

 which have thin foliage, do not kill the sod underneath. It is believed the results 

 would have been much better if other heavy-foliaged kinds, such as larch, spruce, 

 pine, or box elder had been mixed with them. 



Since 1899 other plantations with trees and shrubs have been made in which the 

 spacing has been 2.5 ft. apart. It is too early to report upon these plantings as yet, 

 but it is believed that 3 ft. apart would be as satisfactory or even more so than 2.5 ft. 

 A table is given showing the growth of 20 different species of trees in the forest belt. 

 Black walnut and butternut are making a very slow, unsatisfactory growth where 

 planted on low sandy soil. White spruce is not doing very well on light sandy soil, 

 nor white elm on sandy loam. All these trees have made a much better growth on 

 other soils. 



Forestry in Indiana, S. J. Record (Forestry and Irrig., 11 (1905), No. 3, pp. 

 107-112, jigs. 4). — It appears that 13,000,000 acres, or more than one-half the State of 

 Indiana, consists of broken waste land suitable for tree growth but worthless for 

 agriculture. 



Less than 2 per cent of the total area of the State is now covered with good timber 

 and about 85 per cent of the lumber now used for manufacturing is brought in from 

 other States. The large amount of nonagricultural land is well distributed over 

 the entire State in comparatively small areas. Of the several ways in which it is 

 possible for the State to influence matters in forestry it is believed the only method 

 at present available is that of education and persuasion, by which the farmers can 

 be awakened to the possibilities and advantages of forest planting for posts, fuel, and 

 lumber. 



A brief review is given of the forest legislation of Indiana. In 1903 a law was enacted 

 which provides for the purchase by the State board of forestry of 2,000 acres of land 

 at a cost not to exceed $8 per acre, and $1.50 is to be allowed annually to defray t he 

 expenses of management and labor. This land was purchased in Clarke County, and 

 various experiments are under way to demonstrate methods of sylviculture, tree 

 planting, and forest management. A nursery has been established in which seed- 

 lings will be raised for free distribution to the farmers of the State. 



The Gila River Forest Reserve (Forestry and Irrig., 11 (1905), No. 4, pp. ITS, 

 179). — About 3,640 sq. miles of this reserve has been examined. Of this area 71.25 

 per cent is covered with merchantable timber of extra quality, while 20.25 per cent 

 is naturally timberless. The estimated amount of timber on the reserve is placed at 

 5,867,169,750 ft. B. M., giving an average stand of 3,532 ft. B. M. per acre over the 

 entire timbered belt. About 57.75 per cent of the merchantable timber is yellow 

 pine and 28.37 per cent red fir. 



Progress report of forest administration in the province of Assam, E. S. 

 Carr (A'/)/. Forest Admin. Assam, 1903-4, pp. 64, map 1). — A detailed review of the 

 work of the year, including an account of the timber cut, receipts, and expenses, etc. 



In the work with rubber trees on the Kulsi plantation, 88 acres containing 2,361 

 trees yielded 2,708 lbs. of tree rubber and 1,294 lbs. of mat rubber, or an average of 

 45.5 lbs. per acre and 1.7 lbs. per tree. The cost of tapping was 1,264 rupees and the 

 product brought 11,026 rupees. In the Charduar plantation of 255 acres the average 

 yield per acre in 1903 was 21.7 lbs. or 1.4 lbs. per tree. In 1904 it was 21.79 lbs. per 

 acre or 1.8 lbs. per tree.
