FORESTRY. 779 



The (lestriu'tive nature of forest fires, overgrazing, etc., is pointed out and the neces- 

 sity lor a better system of management is shown. 



Tree planting- in the midlands of Natal, T. R. Sim (Agr. Jour, and Min. Jiec. 

 [XdUil], (J [rjO-!), So. ..'0, pp. 7..'9-7S4). — In a ])ubli!cation noted elsewhere (E. S. R., 

 15, p. 588) the author lias given descriptions of timber trees suitable for jilanting in 

 this region, and the present paper is designed more for the planting of trees as 

 oniaiiientals. It is said that trees desirable for timber production may be used for 

 landscape jjlanting, but many ornamental kinds liave little or no economic value, 

 and on this account it is seldom worth while attemjjting to combine timber produc- 

 tiiiii with scenic effect. In South Africa mixtures of fast-growing trees have usually 

 piDved failures, and the most successful timber plantations are those in which only 

 (uic species is used. 



Notes on the ornamental conifers in the lower Thames Valley, A. Worslev 

 {.fiiiir. U(ni. Hurt. Soc. [London], 28 {1903), iVo.s. J-^', pp. i07-7/i).— Descriptions are 

 given of a number of ornamental exotic conifers that have been planted in the lower 

 Thames Valley, and notes are given on their relative hardiness and adaptability to 

 different systems of planting. 



Forestry, W. Schlich {Agr. Students' Gaz., n. ser., 11 {1903), No. 5, }ip. 131-142). — 

 In a lecture delivered by the author a review is given of the forestry situation of 

 (Jreat Britain, the sources of its present timber supply, and the steps to be taken to 

 restore British forestry. It is said tliat 30 per cent of the land in Great Britain and 

 Ireland is either entirely lying waste or used for rough grazing. Much of this is 

 adapted to forestry, and the author believes that with proper attention it could be 

 advantageouslj^ restocked. 



Experience in Saxony in forest management is cited, and some of the problems to 

 be considered are outlined. The average annual production, cost of planting, value 

 of soils for forestry, etc., are discussed, after which the author states that for 

 economic forestry in (ireat Britain ash, sycamore, and oak should be planted on 

 lands wiiich are adapted to them, and Scotch and Corsican pine and spruce with 

 some larch on other lands. On very wet lands poplar will probably be found to be 

 the most remunerative. 



The exploitation and management of forests, P. Mouillefert {E-cploitation 

 <i (niu'iiageuicid iles hois. Park: Felix Alcan, 1904, pp- 476, pis. 10, figs. 97) . — This is 

 tlie second of a series of lx)oks by the author on sylviculture, and treats of the 

 exploitation and management of forests. After discussing the general laws of tree 

 growth the subject of forest exploitation is taken up and the different kinds of pure 

 and mixed forests are described, suggestions being given for their continued propaga- 

 tion and exijloitation. Chapters are given on the uses of forest products and a 

 special chapter is devoted to truffles and truffle culture. In the second part of the 

 work forest statistics are given and comparisons drawn between the different systems 

 of forest management. 



Forest reserves for public benefit, G. Pinchot {Water and Forest, 3 {1904), 

 No. 4, I'P- 14, -?■')• — In an open letter the author defines the attitude of the Govern- 

 ment toward forest reserves, and seeks to remove much of the current misunder- 

 standing regarding the object and effect of forest reserves. 



Investigations regarding the root development of trees, A. Encjler {Mitt. 

 Seltirviz. <:>ntr(d(inM. Ford. Versdclisu'., 7 (1903), p]i. :J74-317; <dis. in Forestrij Quart., 2 

 {1903\, No. 1, pp. 34, 35). — Investigatifjns are reported on the periodicity of the 

 annual growth of different species of trees, the root activity beginning some time 

 before bud development. An exception is noted in the case of larch, Avhich makes 

 its early transplanting in the spring or late fall planting necessary. The most vigor- 

 ous root growth noted was made in June and July, followed by a decline in August, 

 after which there was in October and November a second period of active growth,
