148 EXPERIMENT STATION RECORD. [Vol 37 



Production of lumber, lath, and shingles in 1915 and lumber in 1914, 

 J. C. Nellis (V. S. Dept. Agr. Bui. 506 (1917), pp. 45, pis. 2, figs. -J).— This 

 bulletin gives detailed statistics on the production of lumber, lath, and shingles 

 in 1915 with comparisons for previous years. The data given include produc- 

 tion, by classes of mills, by States, and by kinds of wood. Reports from 

 16,815 mills showed an aggregate timber cut for 1915 of 31,241,735,000 ft. b. m.. 

 from which it is estimated that the total lumber cut of the country was 

 approximately 38,000,000,000 ft. b. m. 



Forest industries {Statis. Year Book Prov. Quebec, 1916, pp. 42D-44S). — A 

 statistical survey of the forest products of Quebec for 1915, including compara- 

 tive data for 1914. An article on the manufacture of wood pulp, by G. C. 

 Pich6, is also included. 



DISEASES OF PLANTS. 



Additional notes on Philippine plant diseases, C. F. Bakeb (PhiJippine 

 Agr. and Forester, 5 (1916), No. S, pp. 75-7S).— Since the publication of the 

 review of plant diseases previously noted (E. S. U.. 32, p. 749). considerable 

 work has been done in this direction by the author and, in collaboration with 

 him, by Ilehm, Sydow, Saccardo, and Diedicke, in the determination of para- 

 sitic fungi. A number of these are considered as new to science and are 

 named herein, without technical descriptions, in connection with the host 

 plants. These foi-nis include the new varieties Phomopsis palmicola arecce on 

 Areca catechu and Mycogone cervina thcohroma and Xectria bainii hypolcuca 

 on Theubroiiia cacao; the new species Phyllosticta insularum on Annona muri; 

 cata, Exosporium pulchellum and AnthostomcUa arecce on Arcca catechu, 

 Phomotospora migrans on Arenga saccharifera, DiatrypcUa barlerice on Bar- 

 leria cristata, Physalospora guignardioides on Canavalia gladiata, Zignoclla 

 nobilis on Citrus nobilis, Exosporium durum and Chatosphwria cximia on 

 Cocas nucifcra, Phyllosticta euchlwncc on Euchlana luxuriatis, Diplodia crcbra 

 ou ilusa sapientum, Oospora oryzctorum, Phyllosticta glumarum, Ophiobolus 

 oryzinns, Sordaria oryzcti, and Coniosporium oryzinuin on Oryza sativa, Pion- 

 notes capillacea on Persca gratissima, Pczizclla ombrophilacca and Aschersonia 

 parcensis on Psidium guajava, Dlplodina degcneran^ on Solanum melongena, 

 Physalospora affinis and Botryosphcpria minuscula on Theobronia cacao. Macro- 

 phoma trichosanthis on Trichosanthcs anguina, Vertnicularia xanthosomatia 

 on Xautliosoina sagittifolium, and Ilelminthosporium curvulum, Clastcrospor- 

 ium maydicum, BroomcUa zccp, and Acerbic maydis on Zea mays; and the new 

 genera and species Bakerophoma sacchari on Saccharutn officinarum and Dia- 

 cothecium bakcri on Trichosantlics anguina. 



Some Phycomycetous diseases of cultivated plants in the Philippines, 

 N. Mknuiola and II. B. Espino {Philippine Agr. and Forester, 5 (1916), Xo. S, 

 pp. 65-72, figs. 2). — It has been found that Phytophthora fabcri (P. theo- 

 bromcE) is the cause of a pod disease of cacao and a fruit disease of papaya, 

 and it is thought that it may develop on other plants in this region. Though 

 the primary agent in the above-mentioned cases, it is quickly followed by other 

 fungi, commonly by Lasiodiplodia. 



P. colocasicE was found and studied on leaves of gabi (Colocasia antiquorum) 

 at Anos. Los Banos. Pythium dcbaryanum has been noted in the Philippines 

 as causing a damping-off in seedlings of lettuce, tomato, and other vegetables, 

 also in tobacco plants. 



Plant diseases and other injuries, C. Bkick (Hamburg Bot. Staatsinst., Ber. 

 Abt. Pftanzetischutz, 16 {191S-1J,), pp. 9-2i).— This deals with diseases, animal 

 enemies, and other harmful agencies affecting various plants in domestic and
