general preparation for forestry work \i> outlined and attention called to the ojiening 

 for trained foregters in varioun localities. 



Forest planting- and timber supply, F. E. H. W. Krichauff {Jour. A/jr. and 

 JikI. South Austraiid, ', [IHO.'), So. >;, pp. 537-542). — A brief account is given of the 

 development of tree planting in the United States and Germany, after which the 

 production and exportation of lumber and timber in New Zealand and Australia is 

 shown. '^^Mth the present rate of cutting, the author believes that before long there 

 will be a dearth of timl)er throughout New Zealand unless means be immediately 

 taken to restore the cut-over lands. 



Forest planting- and timber supply, F. E. H. W. Krich.\uff {Jour. Agr. and 

 LxL South Aitstnilia. 5 {1902), Xo. S, pp. 668-668).— An account is given of the 

 effect of forests on rainfall and temijcrature, and species of trees suita})le for planting 

 in various parts of Australia are described. Among the summary statements given 

 relating to the effect of rainfall and temperature is an account of 5,000 observations 

 which were made in Bavaria as to the influence of forests on temperature and moisture 

 of the air, also the evaporation of water and rainfall. Observations were made twice 

 a day for a period of 5 years of soil at depths of 6 in., 2 ft., 3 ft., and 4 ft., and at the 

 same time the temperature of the atmosphere was taken. The mean annual tem- 

 perature of the soil of the forest was found to be 21 per cent lower than that of the 

 open field, and the air temperature 10 per cent lower. In this wav the equalizing 

 effect in lowering the extreme summer heat and lessening the winter's cold is 

 shown. 



Progress in tree planting-, W. L. Hall {Forestry and Irrig., 8 {1902), No. 1, pp. 

 40-43, jig!^. 2) . — A review is given of former attempts at tree planting in the United 

 States and a brief description of the present endeavors in this line, not only in the 

 Western, but also in the Eastern and Southern States. With few exceptions, the 

 large plantations now being established are under the immediate direction of the 

 Bureau of Forestry of this Dej)artnient. 



Investments in Southern forests, C. A. Schenck {Tradesman, 46 {1902), Xo. 9 

 {23. annual), pp. 137-139, figs. 4)- — The increase in large holdings of forest areas in 

 the South is noted and is believed to be the beginning of conservative lumbering. 

 Foresting is not believed to be of immediate financial benefit to the small holder on 

 account of the difficulties of marketing the produce, fire protection, time required to 

 produce the crop, etc. 



The boundary line between the desert and the forest, S. J. Holsinger ( For- 

 estry and Irrig., 8 {190-2), No. 1, pp. 21-27, figs. 5). — The author considers the forest 

 conditions of Arizona, calling attention to the effect of the destruction of brush lands, 

 and suggests that greater attention be paid to their protection. By protecting the 

 lesser growth it would be possible to secure the development of forests as generally 

 understood. 



Notes on some forest trees of Ohio, W. R. Lazenby {Proc. Cohunbus Hort. 

 Soc, 16 {1901), pp. 115-118, figs. 2). — Descriptive notes are given of the American 

 linden or basswood, sycamore, black walnut, and white oak, together with notes on 

 their characteristics as forest trees and the value of their timber and other products. 



Forestry in the Philippines ( Queensland Agr. Jour., 10 {1902) , No. 2, p. 126). — 

 A brief review is given of the forest conditions in the Philippine Islands, and the 

 organization of the forestry bureau is commented upon. 



English coppices and copse woods, J. Nisbet {Jour. Bd. Agr. {^Londonl, 8 

 {1901), No. 3, pj). 29.3-305). — An historical statement of the beginnings of arbori- 

 culture in England. 



Forestry in Sweden {Queensland Agr. Jour., 9 {1901), No. 6, p. 570). — The public 

 forests of Sweden are said to embrace 18,000,000 acres, of which 12,500,000 are under 

 scientific management. There is in Sweden a central forestry bureau, and a forestry 

 corps for work in the field, comprising 9 inspectors and 88 chiefs of range, besides
