852 EXPERIMEIirT STATION RECORD. 



Some observations on Polyporus berkeleyi, J. R. Weir {Phytopathology, S 

 (1013), No. 2, pp. 101-104, pi. 1). — The author reports collectins; P. herkeleyi 

 in constant association with the western larch (Larix occidentaUs). There 

 was found no evidence that the mycelium was able to attack living wood, but 

 it appeared to extend into the wood of trees injured by fire. 



Germination studies with spores of Merulius, C. Wehmee (Ber. Deut. Bot. 

 Gesell., 31 (1913), No. 6, pp. 311-316).— The author reports that his attempts at 

 demonstrating reproduction and spread of M. lacrymans by means of spores 

 made under different and favorable conditions were wholly without result 

 though continued for about three years, this outcome being contrasted with 

 that reported by R. Falck (E. S. R., 28, p. 751). An apparent exception to this 

 general result was noted in which old spores were found to be covered with 

 mycelium, but the latter proved to belong to a different species. 



A further account is to appear later. 



ECONOMIC ZOOLOGY— ENTOMOLOGY. 



Directory of officials and organizations concerned w^ith the protection of 

 birds and g'ame, 1913, T. S. Palmer (U. S. Dept. Agr., Bur. Biol. Survey Giro. 

 94, PP- i6).— This fourteenth annual directory of officials and organizations con- 

 cerned with the protection of birds and game in the United States and Canada 

 is arranged on the same plan as those previously issued (E. S. R., 28, p. 56), 

 and has been revised to July 15, 1913. 



The rat, a sanitary menace and an economic burden, R. H. Creel (Pub. 

 Health Rpts. [U. S.], 28 (1913), No. 27, pp. 1403-1408) .—This paper empha- 

 sizes the importance of the rat, particularly as a menace to health. 



The amended insecticide law, C. W. Woodwoeth [Calif orrda Sta. Girc. 104, 

 pp. 10).— This circular gives the full text of the law of 1911 (E. S?. R., 25, p. 

 764) as it now stands with footnotes on each of the changes made in 1913. 



Analyses of insecticides for users, G. P. Gray (California Sta. Girc. 105, 

 pp. 7). — This circular presents rules and regulations drawn up to assist in 

 cari-ying out the provisions of the insecticide law relating to analyses of insecti- 

 cides for users, and gives directions for the sampling of various insecticides. 



Powdered arsenate of lead, A. W. Mokrux (Southwest. Stockman, 1913, No. 

 42, p. 10). — The author concludes that there is no reason why the use of arsenate 

 of lead in powdered form should be discouraged on account of greater danger 

 to workmen in its manufacture or to users in the orchard or garden as com- 

 pared with the paste form of the same insecticide. 



[Insect pests and their control in St. Lucia] (Rpt. Agr. Dept. St. Lucia, 

 1911-12, p. 11; abst. in Rev. Appl. Ent., 1 (1913), Ser. A, No. 3, p. 76).— A capsid 

 i.s reported to have practically destroyed a trial plat of tobacco in the Soufriere 

 districts. The white-headed fungus (Ophionectria coccicola), which attacks 

 scale insects, was found to occur in St. Lucia. The burrowing scale (Howardia 

 hiclavis) on the stems of young GastUla elastica plants in the nursei-y was dis- 

 covered to be parasitized by the red-headed fungus (Splucrnstlllie coccophila). 



Injurious insects in the Government of Moscow during 1912 (Mat. po 

 Izuch. Vredn. Nasiek. Moskov. Gub., 4 (1912), pp. 1-101; abs. in Rev. Appl. Ent.. 

 1 (1913), Ser. A, No. 6, pp. 205-216). — Insects injurious to fruit gardens are 

 discussed by D. M. Korolkov; those injurious to vegetable gardens, by V. A. 

 LeftejGw ; and field pests, by A. D. Baranov. 



[Insect pests in Java] (Meded. Proefstat. Midden-Java, 1912, No. 4, pp. 

 17-23; abs. in Rev. Appl. Ent., 1 (1913), Ser. A, No. 1, pp. S-5).— This is a report 

 on the occurrence of insects of economic importance and investigations thereof.
