1041. PeedRizet, A. Taillis et futaie. [Coppice and high foiest.) Rev. Eaux et Forets 

 58:2-1. 1920. — The rotation of all coppice stands owned by the si iuld be lengthened, 



or else they should be converted into high forest as rapidly as possible, in order to produce a 

 larger proportion of sawtimber. This will involve a certain loss in revenue, which can be 

 minimized, however, if the state will do its own logging. — S. T. Dana. 



1042. Ross, C. R. Annual report of the Forest Department for the year ending 31st March, 

 1919, including report on railway sleeper plantations for the same period. 34 P- Forest Dept. 

 Union of South Africa, 1919. — This is the usual administrative report for the period. The 

 extension and constitution of state forests, management of state forests, financial results, 

 timber imports and exports and general administration are discussed. The protection of 

 forests is given considerable attention especially with respect to insects, fungous diseases, 

 animals and climatic causes. Silviculture is treated rather extensively under the heads of 

 Natural reproduction, Artificial reproduction, Drift sands operation, Cultural operations, 

 Sylvicultural notes and Trial of new species. Detailed information is given on the railway- 

 sleeper plantations. — C. F. Korstian. 



1043. Schlich, Sir Wm. The Bagley Wood sample plots. Quart. Jour. Forest. 13: 266- 

 268. 1919. — Ten experimental plots of important economic forest trees now 10 to 12 years of 

 age, in Bagley Wood (Oxford, England), afford a rather interesting comparison of height and 

 volume growth. The trees and their total average height growth were: Douglas fir (Pacific 

 Coast form), 32 feet; western hemlock, 23 feet; western red cedar, 23 feet; Sitka spruce, 26 

 feet; Japanese larch, 22 feet; Tyrolese larch, 26 feet; Corsican pine, 21 feet; white pine, 19 feet; 

 Douglas fir (Colorado form), 16 feet; and Norway spruce, 15 feet. The trees were all spaced 

 4X4 feet with the exception of Corsican pine, w T hich was spaced 3X3 feet. The annual vol- 

 ume production varies from 306 to 85 cubic feet and follows closely the height growth, with 

 the exception of Corsican and white pines. The annual volume increment of Corsican pine is 

 out of proportion to its height growth because of its close spacing, and white pine has devel- 

 oped an exceptionally large diameter considering its comparatively moderate height growth.

1044. Stoate, P. N. The eucalypts in relation to soil fertility. Australian Forest. Jour. 

 3: 112-113. 1920. — A reply to a paper by Owen Jones (Bot. Absts.), controverting Jones' 

 proposals. [See also Bot. Absts. 6, Entry 1032.] — C. F. Korstian.

 in Jaderborg game reserve, Denmark.] Dansk Skovforenings Tidsskr. 5: 81-86. 4 pi. 1920. 

 — The last trees from three groups of plantations set out in 1765 have been cut. The largest 

 tree measured 1.27 meters in diameter, at breast height, 40.7 m. in height and contained 21.4 

 cubic meters of wood. — J. A. Larsen. 



1046. Weis, Fr. Om Godkning i Skoven. [Fertilization of forest soils.] Dansk Skov- 

 forenings Tidsskr. 5: 102-131. 1920. — A discussion of the needs, means, methods and advan- 

 tages of fertilizing forest soils for greater production of material. — /. A. Larsen. 



1047. Wild. Das iibliche Sprichwort "der erste Wald taugt nichts" trifft nicht immerzu. 

 [The proverb "the first forest is good for nothing" not always true.] Forstwiss. Centralbl. 41: 

 440. 1919. — Actual yield of 80-year-old stand of spruce, which originated from broadcasting 

 seed on an old field (Germany), was 973.75 cu. m. per hectare, or a mean annual growth of 12.17 

 cu. m. per annum. Average middle diameter was 27 cm., average length of stem 26 m. — 

 W. N. Sparhawk.
