538 EXPERIMENT STATION EECORD. 



Yield in uneven-aged stands, B. Moore (Proc. Soc. Amer. Foresters, 9 

 (1914), No. 2, pp. 216-228). — In this paper tlie author analyzes the fundamental 

 difficulties met with in the application of existing methods of determining 

 yields in uneven-aged stands and offers suggestions relative to new methods 

 or modifications of already existing methods. 



Determination of stocking- in uneven-aged stands, W. W. Ashe {Proc. 8oc. 

 Amer. Foresters, 9 (1914), No. 2, pp. 204-206, figs. 2).— The author briefly 

 describes a method of determining the proportion of stocking in uneven-aged 

 stands. This method, it is believed, is applicable for use in connection with 

 any species which occasionally forms pure even-aged groups. 



The measurement of increment on all-aged stands, H. H. Chapman {Proc. 

 Soc. Atner. Foresters, 9 {1914), A'o. 2, pp. 189-203, fig. 1). — A similar paper by 

 the author has been noted from another source (E. S. R., 27, p. 647). 



The use of yield tables in predicting growth, E. E. Carter {Proc. Soc. 

 Amer. Foresters, 9 {1914), No. 2, pp. 1117-188). — A discussion of the nature and 

 use of yield tables as applied chiefly to pure, unthinned stands of New Eng- 

 land white pine. 



Experiments on eccentric growth of ask, Somerville and A. G. Harper 

 {Quart. Jour. Forestry, 8 {1914). No. 3, pp. 218-229, pi. i).— The authors here 

 report data on the eccentric growth of some 5-year-old ashes which were bent 

 over permanently or intermittently in one or more different directions. 



The hardwoods, F. W. Neger {Die Laubholzer. Berlin and Leipsic, 1914, 

 pp. 160, figs. 74)- — This comprises brief descriptions of the native trees and 

 shrubs of central Europe, Including the more important cultivated forms. 



Accretion in the lower part of the steins of both pine and spruce, A. 

 Maass {Meddel. Stat. SkogsfiJrsoksanst. {Mitt. Forstl. Vers. Anst. Schwede^is), 

 No. 10 {1913), pp. 45-58, V. VI, figs. 2). — The author here reports a statistical 

 study of accretion in the stems of pine and spruce between the base of the tree 

 and breast high (1.3 meters) from the ground. 



In the case of pines there appears to be no definite relation between the 

 measurement at 1.3 meters and the diameter accretion either above or below 

 this measurement. In spruce there appears to be no definite relation between 

 the diameter at breast height and diameters above this measurement, but there 

 is a relation between breast-high measurements and the lower part of the 

 trunk. 



The stem height in normal pine stands, A. Maass {Meddel. Stat. Skogs- 

 forsoksanst. {Mitt. Forstl. Vers. Anst. Schicedens), No. 10 {1913), pp. 59-66. 

 VII, VIII, figs. 5). — With yield data secured from 79 pine stands in difiierent 

 parts of Sweden as a basis, the author has platted height and diameter curves 

 for pine trees belonging to different locality classes. 



On some transverse tests of Australian and foreign timbers, J. Nangle 

 (Jour, and Proc. Roij. Soc. N. S. Wales. 47 {1913), pt. 2, pp. 165-173).— A paper 

 on this subject read before the Royal Society of New South Wales. October 1, 

 1913, in which are presented tabulated re.sults of tests of a large n..mber of 

 commercial timbers. The data given .show the breaking load in pounds, modulus 

 of rupture and of elasticity in pounds per square inch, and rate of load in 

 pounds per minute. 



Fire damage in mature timber, J. A. Mitchell {Proc. Soc. Amer. For- 

 esters, 9 {1914), No. 2, pp. 239-244). — The author here presents data dealing 

 with the susceptibility to damage and the power of recovery of various species 

 as observed on the Klamath and Shasta National Forests during the two years 

 1910 and 1911. 



Preservative treatment of timber for estate purposes, J. F. Annand 

 {Quart. Jour. Forestry. 8 {1914), No. 3. pp. 169-186).— The results are given
