1431. Crozier, R. H. The cultivation of eucalypt trees. South African Jour. Indust. 2: 

 234-238. 1919.— Of the numerous species of Eucalyptus, many produce I imbei of exceptional 



value, often unequalled for special purposes by any 'it her timber in the world. They can 

 be utilized to advantage where lightness is not an essential and where their hardness is not 

 a serious drawback. The following species possess qualities of strength, durability, f >r ra- 

 pidity of growth which warrant their extensive cultivation: Eucalyptus cornuta, E. gompho- 

 cephala, E. redunca, E. sidcroxylon, E. paniculata, E. staigeriana, E. hemiphloia, E. rostrata, 

 E. resinifera. E. muelleriana, E. botryoides and E. delagalcnsis. — E. P. Philli 



1432. Crozier, R. H. The properties and characteristics of some eucalypt trees and their 

 suitability for cultivation. South African Jour. Indust. 2: 62-73. 1919. — Eucalyptus mar- 

 ginata (Jarrah) yields an exceedingly durable timber; it is largely used for piles in sea water 

 and in damp ground, and is in demand for railway sleepers, street blocks, etc. The timber 

 from E. diversicolor (Karri) is used for shafts, spokes, felloes, etc. The green-colored tim- 

 ber from E. gomphocephala (Tuart) seasons fairly rapidly and shrinks remarkably little dur- 

 ing the process; it is hard, tough and dense, and is used for framework of railway wagons, 

 skips, beams, etc. The timbers of E. redunca (Wandoo), E. loxophleba (York gum), E. 

 salmonophloia (Salmon Gum), E. longicornis (Morrell) season slowly and shrink to a compar- 

 atively small extent. E. patens, E. calophylla, E. cornuta, E. paniculata, E. crebra, E. 

 siderophloia, E. sideroxylon, E. staigeriana, E. microcorys, E. pilularis, E. maculata, E. 

 saligna, E. propinqua, E. hemiphloia, E. longifolia, E. hemilampra, E. regnans, E. delega- 

 tensis and E. corymbosa are mentioned; the characteristics of their wood and the nature of 

 the soil in which they grow are detailed. — E. P. Phillips. 



1433. Demorlaine, J. Strategic importance of forests in the war. Amer. Forestry 25: 

 1040-1043. 8 fig. 1919.— Translation by Samuel T. Dana from Rev. Eaux et Forets [Paris] 

 Feb., 1919. Revised to date by Percival S. Ridsdale. — Chas. H. Otis. 



1434. Frombling, C. Achtet der niederen Pflanzenwelt. [Observe the lower plant forms.] 

 Zeitschr. Forst.- u. Jagdw. 51: 33-37. 1919. — -A short but highly instructive treatise on the 

 importance of the lower plant forms as indicators of site quality and reforestation possibil- 

 ities. — Hermann Krauch. 



1435. Gaskill, A. Control of growing forests. Amer. Forestry 25: 1284. 1919. — (A 

 contribution to the general topic "A national forest policy.") A policy to be truly national 

 must have in mind the necessities of the nation as a whole, yet recognizing that the greater 

 part of the forest lands in this country are in private possession and under State, not Federal, 

 control. Before growing (not mature) timber can be considered a safe investment for private 

 owners, three things must be established; first, the fitness of a given area for continued use 

 (through one rotation at least) as forest; second, security against destruction; and third, as- 

 surance of the total, or ultimate, tax levy. — Chas. H. Otis. 



1436. Graves, Henry S. A national lumber and forest policy. Jour. Forestry 17: SSI- 

 SOS. 1919. — Halfway measures in handling the forest resource have failed, and will doubtless 

 always fail, because of inherent weaknesses. Cooperation on the part of all agencies whose 

 background is based on the lumber and forest resource is necessary to work out the adjust- 

 ment of international relations, tax reforms, financial aids to the industry, while a policy of 

 forest development making for permanency of operation, improvement in labor conditions, 

 proper and regulated marketing, to encourage proper use of land is badly needed and of 

 great importance to the public as a whole. — E. N. Munns. 



1437. Graves, H. S. The proposed legislation. Amer. Forestry 25: 1281-12S2. 1919. — 

 (A contribution to the general topic "A national forest policy.") Any comprehensive pro- 

 gram of forestry must involve the practice of forestry on privately owned timberlands. It 

 is believed that success can be attained only through some plan of cooperation between the 

 States and the Federal Government, with the States the active agents for carrying the plan
