The characteristics of citrus canker and its eradication, E. M. Doidge 

 (Union So. Africa, Dept. Agr. Bui. 3 (1918), pp. 9, pis. 10). — The purpose of 

 this bulletin is to familiarize growers and handlers of citrus fruits with tlie 

 appearance of citrus canker, which is the most serious of citrus diseases. 



So far as known, all outbreaks have originated in Citrus trifoliata stock 

 from Japan. The disease is said to have been noted in the Philippines, Aus- 

 tralia, South Africa, and the United States. A discussion is given of its chai'- 

 acteristics, dissemination, and possible eradication. A list Is given of places 

 where citi'us canker is found in South Africa, three of these occurring in the 

 Cape Province and the others in five districts of the Transvaal. 



Sixteenth annual report of the [Massachusetts] State nursery inspector, 

 H. T. Fernald (Agr. of Ma^s., 1917, pt. 1, pp. 61-73, pis. 2).— An account is 

 given of work done on wliite pine blister rust to December 12, 1917, by the 

 State nursery inspector in cooperation Avith the IT. S. Bureau of Plant In- 

 dustry, including the planning, prosecution, difficulties, and results of that 

 work. 



The author considers it unwise at this time to attempt a State-wide control 

 of the disease. It is thought that the best policy would be to select the best 

 pine areas and remove all Ribes within 1 mile of such areas for at least a 

 5-year period. 



Disease of the Carolina poplar, A. Beetin (Vie Agr. et Rurale, S (1918), No. 

 17, p. 202; abs. in Rev. Sci. [Parish, 56 (1918), No. U, p. 436).— Mention is made 

 of insect enemies of the Carolina poplar, the chief fungus disease of which is 

 said to be caused by Pleococcum popuHnum. This usually attacks plants not 

 over two or three years old and finds ready entrance at. wounds. It is recom- 

 mended that young trees be sprayed with 3 per cent Bordeaux mixture. 



A disease of Dalbergia latifolia, H. Beekman (Boschbouwk. Tijdschr. 

 Tectona, 11 (1918), No. Jf, pp. 290-293, pis. 2). — A descriptive discussion is given 

 of a canker affecting branches of Dalbergia latifolia noted in 1916 and earlier in 

 several portions of the Dutch Indies, which are named. Suggestions are also 

 given regarding the surgical and sanitary treatment which is recommended. 



Fungus diseases of rubber in Southern India, W. MacRae (Planters' Chron., 

 13 (1918), No. 23, pp. 395-401).— In an address before the Rubber Planters' 

 Conference at Cochin, tlie author dealt in a preliminary paper with the relations 

 of Phytophthora to Hevea and cacao and with measures looking to control of the 

 fungus, the complete classification of which appears to be not yet fully settled. 

 Preventive measures are said to be still in the experimental stage, though re- 

 sults of tests appear to show that removal of fruit and dead branches will 

 prevent the disea.se. The Phytophthora that attacks cacao was found able to 

 cause a fruit rot of Hevea. See also previous notes (E. S. R., 40, p. 852).

Wild animals of Glacier National Park (Washington: U. S. Dept. Int., 

 1918, pp. 210, pis. 37. figs. 94) -—Following a discussion of the general features 

 governing life in Glacier National Park under the headings of physiography and 

 life zones, by V. Bailey (pp. 15-24), the mammals are dealt with by V. Bailey 



(pp. 25-102) and the birds by F. M. Bailey (pp. 103-199). A colored map show- 

 ing the life zones of the park, prepared by V. Bailey from a topographic base 

 man of the T^. S. Geological Survey, is attached.
