452 EXPERIMENT STATION RECORD. 



The renewal of the forests in Cochin China, C. L. Roy {Rev. Eaux et Forcts, 41 

 (1002), Xo. 1, pp. 17-19). — A brief account is given of the attempts being made to 

 properly con.<erve and restore the valuable forests of Cochin China. Attempts have 

 been made to introduce the cultivation of teak, and in 1898 and 1899 1-1 nurseries 

 were established for the .production of teak seedlings. Other nurseries have since 

 teen established and the planting of the young trees in permanent i^lantations was 

 to be bcun in August, 1902. Attention is called to some of the more valuable native 

 timber trees, and their preservation and conservative exploitation encouraged. 



Report of the forester, and the woods of Tonkin, Brenier [Bid. Econ., Dir. 

 Agr. et (Jom. Indo-Chlnn, n. so:, 5 {1902), Xo. 6, pp. 393-4-19).— A report of the for- 

 ester is given in which are included the usual reports of the administration of the 

 forests and the various decrees relative to the exploitation of forests and forest prod- 

 ucts. A list of the forest trees is appended, in Avhich the species are arranged in 3 

 croups based upon their relative timber values. The arrangement is according to 

 vernacular names, the scientific names being given wherever known, and the distri- 

 liution and characteristics of the timber are briefly described. 



Forest trees for calcareous soils, P. Mouillefert {Jour. Agr. Prat., n. .st'r., 3 

 {1902), No. 22, pp. 697, 698). — A description is given of the different kinds of trees 

 adapted to growth in calcareous soils, and the author says that for dry calcareous soils 

 containing a limited amount of clay, sand, iron, and humus, the best species for forest 

 o-rowth is the beech, with birch grown in short rotations. On richer soils which are 

 exploited as coppice, beech, hornbeam, birch, pubescent oak, and species of alder, 

 together with larch and fir in a 25-year rotation, are recommended. For high forests, 

 ash, alder, Ijlack locust, spruce, and Scoth pine in 25 to 30 year rotations are recom- 

 mendtd. 



Profitable tree planting, J. G. Kelly (Jour. Agr. and Ind., Soutli Australia, 5 

 {1902), Xo. 12, pp. 970-972). — An account is given of the income derived from plant- 

 ing a strip of poor sandy land with sugar gum {Eucalgptm corynocahjx) and the 

 broad-leaved wattle. These were planted in alternate rows 6 ft. apart, the land first 

 plowed and harrowed as preliminary to the planting. At the end of the sixth year 

 the wattles were peeled for their bark, but no accurate record was made of the quan- 

 tity of bark taken off. In 1899 each alternate gum tree was removed, those cut mak- 

 ing poles 18 to 20 ft. in length with a mean diameter of 4j in. The estimated cost 

 of growing the trees and wattles from 1891 to 1902 was about $80, while the bark and 

 poles removed, together with the trees now standing, are estimated as worth $140. 



Trees for shelter {Agr. Jour, and Min. JRec, 5 {1902), No. 14, pp. 45S, 459).—T\\q 

 importance of shelter belts for protecting orchards, gardens, etc., against the cold 

 winter and the hot drying winds of summer is pointed out, and the availability of a 

 number of species of Australian and other trees for use as shelter belts in Australia 

 and South Africa is described. 



Street tree planting- {Forest Leaves, S {1902), Xo. 9, pp. I4O-I42). — A report is 

 given on trees for street planting and an account of the results of the street tree plant- 

 ing in Washington, D. C, Ijetween 1873 and 1887. During that time there were said to 

 have been planted in Washington 78,000 trees, represented ])y 30 varieties, but seven- 

 eighths of the number were embraced by 10 or 12 species. The characteristics of the 

 different species for street planting are mentioned. The species best suited to the 

 purpose, as shown by tlie results obtained, are the silver maple, Norway majale, 

 American elm, sycamore, American linden, tulip tree, Carolina poplar, ash-leaved 

 maple, gingko, and pin oak. 



Shade trees, W. A. Murrill {Xew York Cornell Sta. Bui. 205, pp. 24, pis. 3, jigs. 10).— 

 The ol)iect of this bulletin is to aid in increasing the growing interest in shade trees 

 as material aids to the healthfulness and atti-activeness of cities and towns, and to 

 consider the principles underlying their selection and care. After a discussion of the 

 value of shade trees, with some account uf the various kinds found in different cities,
