data the author has brought together will prove of great service in determin- 

 ing the economic relations of a number of species. 



The Tussock Moth in Orchards, by W. J. Schoene, N. Y. Agric. 

 Expt. Sta. BuU. 312, p. 39-49, 1909. 



This bulletin discusses an outbrealc by the white marked tussock moth in 

 orchards near Lockport, N. Y. An unusual though not unprecedented feature 

 was the eating of the young fruit by the caterpillars. The author gives 

 preference to the collection of the egg masses and spraying with arsenical 

 poisons. The value of this bulletin is greatly enhanced by an excellent series 

 of original illustrations. 



The Peach Tree Bark Beetle, by H. F. Wilson, U. S. Dep't. 

 Agri., Bur. Ent. Bull. 68, Prt. 9, p. 91-108, 1909. 



This is an extended discussion based upon original investigations of 

 PhlcEotribus Uminaris Harris. As control measures, the author tentatively 

 advises severe trimming of all badly infested trees, burning the infested 

 branches, and the application of a thick coat of whitewash three times each 

 season to those slightly infested. A fine series of original illustrations adds 

 greatly to the value of the bulletin. 



San Jose Scale in Oklahoma, by John F. Nicholson, Okla. Agric. 

 Expt. Sta. Bull 79, p. 67-88, 1908. 



This is a general discussion of the San Jose scale, accompanied by experi- 

 mental data on methods of controlling the same. We seriously question the 

 wisdom of advising, in a popular bulletin, .0088 of an ounce of cyanide potas- 

 sium per cubic foot of space, in the face of the fact that the employment of 

 one ounce to 100 cubic feet of space has given such universal satisfaction. 



Home-Made Soluble Oils for Use Against the San Jose Scale, 

 by J. L. Phillips, Va. Agric. Expt. Sta. Bull. 179, p. 77-88, 1908. 



This bulletin gives formulae for the preparation of several soluble oils, to- 

 gether with the results of a series of exi^eriments. The author advises the ex- 

 perimental use of these substances against San Jose scale and maple scale, 

 and concludes that these mixtures can be prepared at home for about % 

 the cost of the commercial article. 



Current Notes 



Conducted by the Associate Editor 



Dr. Fr. Schwaugart, who was recently appointed chief of the zoological 

 section of the state experiment station for the study of fruit and viticulture 

 in Rhenish Bavaria, is making an investigation of the insects injurious to 

 these crops. He desires to secure American publications on such insects and 

 would greatly appreciate any such publications that are sent to him. Ad- 

 dress, Dr. Fr. Schwangart, Neustadt a. d. Haardt, 9 Maximillianstrasse, 

 Rhenish Bavaria.
