FORESTRY. 10 79 



The effect of deforestation on climate is mentioned and attention called to the fact 

 that the forest area of Great Britain is considerably smaller than is believed to be 

 the proper proportion for the best agricultural conditions. Considerable attention 

 is paid to the subject of jilanting, in which it is shown that the cost of planting 

 ranges from $7.20 to ?20 per acre, as it appears from the returns from a number of 

 large plantations. Among the species suggested for extensive planting the Scotch fir 

 and larch are generally recommended, although the larch suffers considerably by 

 disease. In addition to these trees a number of species of pines, as well as silver fir, 

 cedar, and hard woods, are recommended. 



In the appendices supj)lemental statements are made on a number of subjects, 

 such as the relative merits of British and foreign timbers, the income from a mixed 

 larch and fir wood at the end of its seventy-fifth year, receipts and expenditures 

 from the clearance of an 18-acre mixed forest of about 75 years' growth, suggestions 

 for the improvement of British forestry, outline of courses in forestry, description 

 of various schools of forestry and their courses of instruction, timber tests of tele- 

 graph i)oles and cross arms, and area of crown forests in the United Kingdom. 



Report of the forestry bureau July 1, 1901, to September 1, 1902, G. P. 

 AiiEKN {]V(ir Dept., Buravt of Iiisulnr Affair.'^, PhUijiplne ('(im. ]>'/)(. HX).', pi. 1, pp. 

 -^'>l-r)27, ph. 37, map 1). — A detailed report is given of the progress made by the 

 bureau of forestry during 1901-2. Numerous additions to_the scientitic staff are noted 

 and also the organization of several new divisions and laboratories. The personnel of 

 the scientitic and administrative staffs is shown, the administrative staff consisting 

 of 4 assistant inspectors, 10 assistant foresters, and 65 forest rangers. 



Descrij)tions are given of the facilities provided for work in the different lines of 

 investigation. Summaries are given showing the licenses granted between July 1, 

 1901 , and August 31, 1902, for cutting timber, also the number of sawmills, employees, 

 output, market value and income derived by the Government from all franchises for 

 the utilization of forest products. The revenue derived during the time covered by 

 the report was $348,073.08 ]\Iexican, the Government charges l)eing l)etween 5 and 

 10 per cent of the market price of the timber in Manila. Valuation surveys have 

 been begun and the results already obtained indicate a conservative estimate of an 

 average stand of 3,500 cu. ft. of timber 20 in. in diameter, on over 20,000,000 acres of 

 virgin forest. The total forest area of the archipelago is estimated at 48,112,920 

 acres, less than 1,000,000 of which is held by valid private title. 



The forests are described and their principal species indicated, together with their 

 groupings under the forest regulations adopted by the bureau. A ])reliminary work- 

 ing i)lan of Bataan Province, prepared by R. C. Bryant, is given in which the neces- 

 sary operations for conservative lumbering are described. Investigations by P. L. 

 Sherman on the forest products of the islands are also reported, particular attention 

 having l)een given to the gutta-percha industry, the permanency of whicli is threatened 

 by wasteful methods of exploitation. 



Progress report of the forest surveys in Bengal, India, 1901-2, P. J. 

 Gordon {CalcuUa: Sujit. dorl. Printing, 1903, p]>. 11, map 1). — A progress report is 

 given of forest surveys in India for 1901 and 1902 in which the character of the sur- 

 vey is indicated, and the extent of the surveyed and unsurveyed forest area is shown. 

 The cost of the survey by provinces is given. The survey during tlie period covered 

 by this report was quite extensive, and attention is called to the fact that it will be 

 impossible to continue the work at the present rate without more adequate jirovisions 

 for carrying on the work. 



The production of timber in Algeria, J. Trabut {Bui. Agr. Algcrie et Tanisie, 

 9 {1003), Ko^. ;?, pp. 25-28; 3, pp. 65-59). — A description is given of the forest condi- 

 tions of Algeria, and attention called to the rapid disappearance of the Algerian 

 forests wherever they occur in accessible regions. On account of the disappearance 

 of trees of a size adapted to construction timber, the author suggests the artificial
