446 EXPERIMENT STATION EECOED. 



The author concludes that June and July precipitation seems to have most 

 effect upon the width of oak rings. Decrease of width more than 0.5 mm. be- 

 low normal would appear to be quite certain indication of a subnormal summer 

 rainfall. Although an increase in width did not necessarily appear to be .an 

 effect of extra abundant rainfall, this holds in 62 per cent of the cases. 



It is pointed out that, generally speaking, the examination of this tree does 

 not show an accurate ratio between ring width and the rainfall since other 

 unknown factors, such as temperature, insect pests, height of surrounding 

 timber, etc., have a disturbing influence. 



The present status of cultural experiments with foreig'n timber species 

 in the state forests of Saxony, F. W. Neger (Naturw. Ztschr. Forst u. Landw., 

 12 {1914), No. 1, pp. 1-11). — Notes are given on the present status and condition 

 of a number of foreign timber species which have been under observation in the 

 state forests of Saxony during the past 10 years. 



The forest flora of New South Wales, J. H. Maiden {Sydney, N. S. Wales: 

 Govt., vol. 5, 1910, pts. 1, pp. 19; 2, pp. 21-52; 1911, pts. 3, pp. 53-68; 4, pp. 

 69-89; 5, pp. 91-103; 6, pp. 105-124; 1912, i)ts. 7, pp. 125-145; 8, pp. 147-158; 

 9, pp. 159-177; 10, pp. 179-191, pis. 67; Index, 1913, pp. Z/).— This is the fifth 

 of a series of volumes on the forest flora of New South Wales, the first of 

 which was issued in 1903. In the present volume 38 species are described, each 

 species being considered with reference to its botanical characteristics, common 

 and scientific nomenclature, size, habitat, econ(«nic products, and propagation. 



Atlas of the tree species of Java, S. H. Koordees and T. Valeton (Atlas 

 der Baumarten von Java. Leiden, Netherlands, 1913, vol. 1, Nos. 1, pp. VII, 

 pis. 50; 2, pis. 50; S, pis. 50, 4, pp. 14, pis. 50).— This atlas, which is issued in 

 4 parts, constitutes an appendix to the author's series of contributions on the 

 tree species of Java (E. S. R., 25, p. 142). The illustrations for each species 

 in the atlas consist of a flowering twig, floral and leaf parts, and in most cases 

 a sketch showing the general appearance of the tree. No descriptions accom- 

 pany the illustrations, but reference is made to the descriptive text in the 

 authors' previous publications. 



Some Doug-las fir plantations. — III, Llandinam plantation, Montgomery- 

 shire, F. Story (Jour. Bd. Agr. [Londonl, 20 (1913), No. 8, pp. 690-696, figs. 

 2). — In continuation of previous observations on Douglas fir plantations (E. S. 

 R., 30, p. 46) growth and yield tables are given for a 28-year-old stand grow- 

 ing in mixture with larch in Montgomeryshire, North Wales. 



Lupine straw as a means of improving" the growth of fir stands on drift- 

 ing sand, E. Hesselink (Cultura, 25 (1913), No. 304, PP- 455-466, pi. 1, figs. 

 5). — In the experimental tests here reported lupine straw was used as a 

 ground covering and compared with the sparse native vegetation which was 

 simply mowed and left on the ground. Stands of fir in which the lupine straw 

 was used were found to make a much greater root and top development. 



Forest management of loblolly pine in Delaware, Maryland, and Vir- 

 ginia, W. D. Stereett (U. 8. Dept. Agr. Bui. 11, pp. 59, pis. 5, fig. l).—ln order 

 to show the financial possibilities in growing loblolly ^ine in Maryland, Dela- 

 ware, and Virginia the author here presents and discusses data dealing with 

 the rate of growth and yield; past, present, and prospective lumber prices; cost 

 of lumber production ; stiunpage values ; expectation values for different initial 

 investments, rotations, types of soil, and distances from market ; cost of various 

 silvicultural operations ; and size, volume, and yield tables The best systems 

 of management are described, and the loblolly pine is also considered with ref- 

 erence to its nomenclature, botanical and silvical characteristics, utHization, 

 and characteristics of the wood.
