1058 EXPERIMENT STATION RECORD. 



The third disease described is termed l)U(l rot disease, aud was noticed in 

 several isolated districts. The cause of the trouble is said to be somewhat 

 obscure. The roots and stem of the palm appear healthy, while the bud is 

 involved in a vile-smelling soft rot. In one instance a fundus was found in the 

 advancing margin of the diseased part, but generally bacteria were the only 

 organisms present. Three different species of bacteria have been observed in 

 connection with this disease, but as yet no definite data have been obtained as 

 to how they gain entrance to the tree or whether they are the primary caiise of 

 the disease. It is thought that careful cultivation and the prompt destruction 

 of diseased material would tend to keep this disease in check. 



The effect of alkaline polysulphids on spraying apparatus, M. Fremont 

 {Prog. Ai/r. ct Vif. (Ed. VEst), 28 {I'.m), So. 11, pp. 320-.JS1).— Attention is 

 called to the fact that in using alkaline polysulphids as fungicides the solutions 

 attack copiier lined spraying apparatus. On this account such apparatus should 

 be heavily tin lined to prevent the injurious action of the fungicide. 



ECONOMIC ZOOLOGY— ENTOMOLOGY. 



Inheritance of acquired characters, A. Weisman and R. Semon (Arcli. 

 Rasseii ti. Grscll. Biol.. 3 (HHIG). Ao. I. pp. 1-27 ; Jf {1901), No. 1, pp. 1-46).— 

 The controversy set forth in these articles c(nicerns the old problem of whether 

 acquired chai'acters in animals may be inherited, the negative side of the ques- 

 tion being taken up by Weisman and the affirmative by Senion. The latter 

 authority maintains that it is impossible to discuss heredity in an unprejudiced 

 manner so long as it is assumed that acquired characters can not be inherited. 



The zoological record, D. Sharp {Zool. Rec, J,2 {1905), pp. LXV+1201).-~ 

 As in previous issues of this annual publication elaborate classified biblio- 

 graphies are given of the literature relating to all branches of zoology. The 

 bil>liograi)bies of the various subjects have been worked uji by members of the 

 record conmiittee of the council of the zoological society of London. The volume 

 covers the literature published in 190.5. It is announced that the volume for 

 11)06 will be a joint production of the international catalogue organization and 

 this committee. 



The monthly bulletin of the division of zoology, H. A. Surface {Penn. 

 Dcpt. Agi:, Mo. Bui. Div. Zool.. ', (1907). \o. 10. pp. 353-382, i)ls. 2).— Brief 

 recommendations are made I'egarding the use <^)f carbon bisulphid in combating 

 insect pests of beans, peas, and other seeds ; the treatment of San .lose scale 

 with lime-sulphur wash and connnercial insecticides; and the results obtained 

 by connnercial orchardists in combating this pest. 



Report of the entomologist, C O. Houghton (DcUnrarr ,Sta. h'pt. 1903, pp. 

 I'l 1-159. pi. 1). — In spraying for San Jose scale boiled lime-sulphur wash gave 

 better results than the unboiled wash. Pure kerosene did not injure native plum 

 trees, but caused some injury to apple and pear trees. In commercial orchards 

 little difference was seen in the results from the use of boiled and unboiled 

 lime-sulphvu' washes. 



Snowy tree-cricket is reported to have caused injury to the trunk of a plum 

 tree. Brief reports are also made on the Indian-meal moth in jelly, fumigation 

 for the white fly, Cliiloconis .^iniilis. the codling moth, the oyster-shell bark- 

 louse, the mnshrooni maggot, and the strawberry weevil. 



Division of entomology, A. Craw (Rpt. B<1. Coiiirx. Agr. (iiid Forc^trii
