1458. McCarthy, E. F. Observations on unburned cut-over lands in the Adirondacks. 

 Jour. Forestry 17: 386-397. Fig. 1-2. 1919.- Lopping methods must insure the destruction 

 of hardwoods to insure :i stand of spruce as the diameter limit favors I he hardwoods through 

 cleaning up the forest and reducing the fire risk, while the heavy cutting of hardwoods increases 

 the fire risk through slash accumulations and encourages hardwood reproduction. Tn the 

 latter method softwood trees mature more quickly than in the diameter limit method, but 

 the slow growth and late recovery of spruce necessitate subsequent cuttings of hardwoods 

 before the spruce will make a free growth. Hardwoods can be produced in this type of ex- 

 cellent quality in a short time in spite of the desire to commit it to a pure conifer us forest. 

 — E. N. Munns. 



1459. Mellstrom, Gosta. Skogstradens frosattning ar 1918. |See nroduction of forest 

 trees in 1918.] Meddel. Statens Skogsforsoksanst. 16: 1-26. 4 fig. 1919.— The article 

 gives a survey of the seed crop of the more important forest trees in Sweden in 1918, and a 

 statement of the amounts available for reforestation. The supplies throughout the country 

 are below normal, due partly to deficient production and partly to the scarcity of labor 

 for collection. — G. A. Pearson. 



1460. Munns, Edw. N. Control of flood water in southern California. Jour. Forestry 

 17: 423-429. 1 fig. 1919. — Flood control work in the United States on a definite scale began 

 in the San Gabriel Mountains with the installation of check dams. The influence of these 

 on the run-off during a subsequent flood period is described in detail. — E. N. Munns. 



1461. Neger, F. W., and G. Buttner. Der forstbotanische Garten (Forstgarten) zu 

 Tharandt. [The Tharandt Arboretum.] Tharandter Forst. Jahrb. 70: 33-71. 5 pi. 1919. — 

 A brief description of location and size, and of soil and climatic conditions, is given, together 

 with statement of purpose of arboretum. A list of the principal trees and shrubs is cited. 

 This arboretum is now over 100 years old and contains many fine trees, among them being 

 a number of exotics. — Hermann Krauch. 



1462. Olmsted, Frederick E. The work ahead. Jour. Forestry 17: 227-235. 1919 — 

 Two tasks confront the forester at the present time due to a lack of understanding on the part 

 of the lumberman as to their relationship to national welfare: (1) to compel the private owner 

 of forest lands to keep his soils productive; (2) to decide whether timber lands should be in 

 private or public ownership, and how they should be managed and controlled. — E. N. Munns. 



1463. Peters, J. G. A program of forest conservation for the south. Jour. Forestry 17: 

 364-370. 1919. — Little can be done to induce the southern states to grow timber unless def- 

 inite figures can be given them. Cooperation between the states and the government is 

 necessary in the classification of lands, the acquisition of cut-over and waste lands, cooper- 

 ation with private owners and in research work. — E. N. Munns. 



1464. Ridsdale, P. S. War's destruction of British forests. Amer. Forestry 25: 1027- 

 1040. 16 fig. 1919. — A letter written in London, Feb. 8, 1919, discussing the cutting of British 

 forests for wartime needs, reafforestation and future forest activity, together with a brief 

 history of British forests. — Chas. II. Otis. 



1465. Sparhawk, W. N. Comment on Professor Terry's article. [Criticism of: Terry, 

 E. W. A formula method for estimating timber. Jour. Forestry 17: 413-421. 1 fig. 1919. 

 (See Bot. Absts. 3, Entry 1467.)] Jour. Forestry 17: 421-422. 1919.— A method is given 

 whereby the values of the constant can be obtained much more quickly than in the original 

 manner. — E. N. Munns. 



1466. Stuart, R. Y. Scouting for timber in the eastern Pyrenees. Amer. Forestry 25: 

 1193-1198. 5 fig. 1919. — Notes on the trees and stands and French logging methods in the
