use of garbage wherever feasible appears to be desirable, since it increases the 

 moisture content of the soil and furnishes available plant food for the trees.

 H. G. BiLLSON, J. C. TuLLOCH, and F. Canning (Ann. Rpt. Forest Admin. West., 

 East., and Kumaun Circles [IndiaJ, 1913-14, pp. 5+57+XC+S).—Thi>i is the 

 usual report on the administration, management, silvicultural operations, 

 and exploitation of the state forests in the Western, Eastern, and Kumaun 

 Circles of the United Provinces, including a financial statement for the forest 

 year 1913-14. 



All imporant data relative to the forest areas, forest surveys, working plans, 

 forest protection, and miscellaneous work, yields in major and minor forest

Progress report of forest administration in the Punjab for the year 

 1913-14, R. MclNTOSH (Rpt. Forest Admin. Punjah, 1913-14, pp. 7+II+20+

The production of lumber in 1913 (U. 8. Dept. Agr. Bui. 232 {1915). pp. 

 82, flys. 2). — A statistical report on the production of lumber in the United 

 States in 1913, prepared by the Forest Service in cooperation with the Bureau 

 of Crop Estimates. 



Detailed data are given showing the production of the important kinds of 

 lumber by States and the number of active mills in each State, together with 

 data showing the total production of minor species of lumber and the principal 

 Sates reporting same. Comparative summaries of production by States and 

 species are given for 1913, 1912, and 1911. 



In 1913 a total production of 38,387.009,000 ft. b.m. was reported, as com- 

 pared with 39.158,414,000 ft. in 1912. Soft woods contributed 30,302,549,000 ft. 

 b.m. in 1913, as compared with 30,52G,41G,000 ft. in 1912. 



DISEASES OF PLANTS. 



[Investigations in plant diseases] {Wisconsin Sta. Bui. 250 {1915), pp. 

 33-39, fi(js. 4). — A summary report is given of work carried on by the depart- 

 ment of plant pathology during the year, the investigations consisting of a 

 plant disease survey, and experiments with rot-proof cabbage, onion smut, and 

 pea blight. 



In connection with the plant disease survey a new disease of cucumber, 

 known as " white pickle," has been discovered. It affects both vine and friiit, 

 causing serious losses. The cause is as yet undetermined. 



In continuation of the experiments in the production of cabbage immune to 

 the disease known as yellows, one strain has been developed and seed placed 

 in the hands of selected growers. A stand of from 95 to 99 per cent of the rot- 

 proof type was obtained, as compared to 15 to 20 per cent of a crop where 

 Imported Danish and Puget Sound seed was used. Efforts are being made to 

 produce a seed of this resistant strain on a commercial scale in the Puget 

 Sound region. 



A continued investigation on the prevention of onion smut by the use of form- 

 aldehyde solution has shown that the treatment greatly reduces the amount of 

 disease at a cost of about $4 per acre for the fungicide and its application. 



The pea-blight investigation during the year has been extended to study 

 the influence of drainage. Where land that had been previously cropped 

 with peas was thoroughly drained but little blight was observed, while on the
