plants added during the year to the flora of Hong Kong and adjacent territory. — The report 

 discloses that the total rainfall at the Botanical Gardens for the year was 85.51 inches of which 

 almost 33 inches fell in July. Typhoon signals were hoisted four times and considerable dam- 

 age was done by these storms to the vegetation. Species of Melaleuca, Casuarina, Eucalyp- 

 tus, Tristania, Aleurites, and Celtis were planted for forestry purposes. The clearing of un- 

 dergrowth at Government expense for anti-malarial purposes amounted to over 5,000,000 

 square feet. The revenue amounts to only 14 per cent of the annual expenditures in this 

 department. — Richard H. D. Boerker.

 — Chiefly comment regarding a paper on "The rubber industry — past and present" presented 

 by B. D. Porritt (Chief Chemist to the North British Rubber Company, Ltd., of Edinburgh) 

 before the Royal Soceity of Arts. Of interest is a tabulation by countries of the consump- 

 tion of raw rubber in 1917. The United States consumed 69 per cent of the total against 

 10.2 per cent by Great Britain. — H. N . Vinall. 



1424. Anonymous. Transplanting large trees. Amer. Forestry 25: 1198. 1919. — In 

 transplanting mature trees the chances of success are best with elm; but maple, horse chest- 

 nut, catalpa, ash, linden, willow, poplar and pin oak can be transplanted with more or less 

 success if the proper methods are employed. — Chas. H. Otis. 



1425. Babbitt, W. H. Uncle Sam, lumberman, Canal Zone. Amer. Forestry 25: 1265- 

 1267. 5 fig. 1919. — A description of the saw-mill and lumber business operated by the United 

 States Government on the Panama Canal Zone, with notes on the characteristics of the trees 

 of the region, especially espavay, lignum-vitae, nispero or bullet-tree and almendra. —

1427. Brown, Nelson Courtlandt. Forestry and the war in Italy. Jour. Forestry 17: 

 408-412. 1919. — The forest resource of Italy suffered heavily during the war because of the 

 lack of imports, increased demands from industry, the lack of a coal supply, and destruction 

 in battle. The future supply will have to come largely from plantations to the extent of 

 some 30 per cent of the area of the country. — E. N. Munns. 



1428. Chandler, B. A. Results of cutting at Ne-ha-sa-ne Park in the Adirondacks. 

 Jour. Forestry 17: 378-385. Fig. 1-3. 1919. — The working plan for the mixed conifer and 

 hardwood forest in 1898 failed to give the results looked for, as hardwoods took advantage of 

 the spruce which is competing with other plants throughout its life. Hardwoods seeded down 

 better, grew more readily, and responded to environmental changes more rapidly than did 

 spruce. Apparently management for spruce demands intensive methods, cutting hardwoods 

 as closely as possible and freeing spruce unless badly suppressed. The diameter limit of cut- 

 ting is a failure, and favors hardwoods. The best method is probably clear-cutting and plant- 

 ing. — E. N. Munns. 



1429. Clapp, Earle H. Forest research and the war. Jour. Forestry 17: 260-272. 1919. 

 — During the war period the activities of the research branch of the U. S. Forest Service were 

 spread to include practically every use of wood in modern warfare in addition to non-military 

 uses. Savings to the government in the two years of war more than paid for all the money 

 which has been expended without attempting to measure the indirect benefits. The great 

 need for further investigations is emphasized. — E. N. Munns.
