stands, natural and artificial reproduction, and the maintenance of the stand. 

 Part 2 takes up the various deciduous and coniferous trees relative to their 

 special characteristics, cultural requirements and treatment. 



The arboretum of the Boyal High School of Agriculture, Horticulture, 

 and Forestry at Wageningen, J. Y. Sitringar {Meded. Rijks Hoogerc Land, 

 Ttiiii cu Bo-schl)oiiii:sch., 3 (1910). No. 2-5, pp. 119-213, pis. 3).— This consists 

 of a short review of the nature and history of dendrology and of the literature, 

 nomenclature, and origin of our tree species, together with a list of species 

 growing in the arboretum which includes botanical names and synonyms, geo- 

 graphic distribution and other notes. 



Increment investigations with spruces, Usener (Allg. Forst u. Jagd. Zfg., 

 86 (1910), pp. 122, 123). — Comparative tables are given showing the diameter 

 and volume accretion of some 243 firs and 133 spruces examined in the com- 

 munity forests of Ranrupt and Colron-la-Roche in Alsace-Lorraine. 



Soil physics investigations in m.ixed stands of oak and beech, R. Wallen- 

 BOCK (Ccntbl. Gcsam. Forstic, 36 (1910), No. J,, pp. i.5/-i56).— R<^sults are given 

 of a series of investigations conducted in oak and beech stands to determine 

 the relation between the kind of soil cover and the physical character of the 

 soil. 



The author concludes that the physical character of forest soils is influenced 

 by the kind of tree in the stand and its accompanying soil cover. The dead 

 soil cover found underneath pure beech stands increased the water capacity of 

 the soil in a much greater measure than the vegetative soil cover found under- 

 neath pure oak stands. Loamy soils in pure beech stands are favorably in- 

 fluenced by the action of the leaf mold cover to a depth three times as great 

 as in an oak stand. Where oaks and beeches grow in a mixed stand, the 

 greater the percentage of beech trees the greater the water capacity of the 

 soil. 



The results of similar investigations along this line are also noted. 



The effect of the forest upon waters, P. Buffault (Rev. Eaux ct Forfts, 

 -}8 (1909), Nos. 1, pp. 1-18; 2, pp. 33-.', 'i ; Anicr. Forestry, 16 (1910), No. 3, pp. 

 151-173). — This consists of a summary of the results of European investiga- 

 tions relative to the influence of the forests upon stream flow and upon the 

 sources of water, including a review of this question as discussed at the Con- 

 gress of Navigation held at Milan in 1905. 



The opportunities in forest planting for the farmer, A. S. Peck (U. 8. 

 Dept. Agr. Yearbook 1909, pp. 333-3U, pis. J,, fig. i).— In this article the author 

 points out the necessity for utilizing the farm woodlot to the best advantage 

 and of establishing new forests on treeless areas, both for protection and as 

 a commercial proposition. Suggestions are given relative to the methods and 

 species by which this may be best accomplished in the different sections, in- 

 cluding data on what has already been done along this line by the Government. 

 State, and private individuals. 



Basket-willow industry, F. Dillingham (Wcckh/ Cons, and Trade Rpts. 

 [U. /S.], 1 (1910), No. 11, p. .'/9i).— This consists of notes on the character of 

 the basket-willow industry in the Bavarian district of Upper Franconia. 



[Forest resources in Maryland], B. N. Baker, W. B. Clark and E. Hirsch 

 (Rpt. Conserv. Com. Md., 1908-9, pp. 119-135, pis. 2, fig. 1).—In addition to a 

 brief survey of the forest resources of the State, this report discusses wasteful 

 methods of lumbering, forest fires, the farmer's woodlot, the use of the forests, 

 and the relation of forests to stream flow, concluding with suggestions for the 

 development and conservation of the woodlands in the State. 



Forest conditions in South Carolina, W. M. Moore (Dept. Agr. Com. and 

 Indus. [S. C] Bui. 1, pp. 54, figs. 7), — This report embodies the results of a
