FORESTRY. 1083 



( aliiDiuia forests carried on with the Bureau of Forestry of this Dei)artment. This 

 work was made possible through a State apjjroj^riation which became availa))le July 

 1, U(03. The work thus far performed consists of mapping and describing 17,250,000 

 acres of forest land, together with suggestions for its proper management, studies of 

 the problems of tire destruction and prevention, and forest extension. A plan has 

 been provided for lire protection which has been put in oj^eration on a small scale 

 on a tract of land in order to test the exact cost -of such protection. 



Under the forest extension studies, investigations have been pursued in the repro- 

 (hiction of the forests in the San Gabriel, San Bernardino, and San Jacinto moun- 

 tains to determine the methods of forest reproduction. In the same regions a study 

 is being made of chaparral to determine its extent, condition, and importance as a 

 cover. Investigations are also being made on the growth and area of planted euca- 

 lyptus, as well as on jaroblems of forest fires. 



The revenue to be expended in this investigation up to December 31, 1904, is 

 approximately $15,000, $6,028 of which is provided by the State of California, the 

 balance, being salaries and other expenses, paid Ijy the Bureau of Forestry of this 

 Department. 



An outline is given of the work to be pursued during the coming season, and esti- 

 mates made as to its cost. 



Planted pine in Nebraska, C. A. Scott {Forestr;/ and Irrig., 10(1904), Ao. 2, 

 pp. 77-70, fit). 1). — A report is given of a plantation started 13 years ago in the sand 

 hills of western Nebraska. The plantation consisted of about one-half acre and was 

 planted in the spring of 1891 with 3-year-old seedlings in alternate rows of jack pine 

 {Piuus divaricata), and Scotch, Austrian, Norway, and western yellow pine. 



The jack pine seedlings were secured from forests, and about 50 per cent of them 

 died during the first year. Since planting the trees have received no cultivation 

 whatever, but have been protected from fire and stock with the result that fully 90 

 per cent of those surviving the first season have made a comparatively good growth. 

 The jack pine has by its growth proved adapted to the conditions of the sand hills, 

 the dominant trees averaging 19.4 ft. in height and 3 in. in diameter breast high, 

 with the intermediate trees about 15 ft. in height. The estimated volume of wood 

 on the half acre was 586.2 cu. ft. Many individual specimens of the other species 

 of pines are making thrifty growth, but are hardly to be compared with those of the 

 jack })ine. 



The blue g-um, J. B. Anderson (Forestry and Irrig., 10 (1904), No. 2, pp. 65-70, 

 figs. 3). — A study is given of Eucalyptus globulus and other species of the same genus 

 in California. The forest characteristics of blue gum are described; its value as tim- 

 ber pointed out, and metliods of planting, cultivation, etc., enumerated. The blue 

 gum is said to be one of the most rapid growing trees, and on average soil in Califor- 

 nia will produce 500 cu. ft. of new wood per acre each year. In addition to E. 

 globulus a number of other species of less extended distribution are enumerated and 

 Ijriefly described. 



Practical forestry for lumbermen, O. W. Price (Forestry and Irrig., 10 (1904), 

 No. 2, pp. G0-G3). — This is an address given before the Southern Lumbermen's 

 annual meeting at New Orleans, in which the author gives reasons for conservative 

 handling of timber lands and the financial results that may be expected from such 

 treatment. 



■Wood pulp and wood-pulping- macMnery (Queensland Agr. Jour., 14 (1904), 

 No. 1, pp. 44-46). — On account of fre(juent inquiries regarding wood pulp and its 

 manufacture, the ilepartment of agriculture of Queensland has prepared a statement 

 showing the various kinds of timber suited for wood pulp and describes some of the 

 more important processes in its manufacture. According to the article there are in 

 operation in the United States 1,115 paper and pulj> mills with an annual output of 

 2,500,000 tons of paper, tlie greater portion of which is made from wood pulp.
