year, special studies being made upon root maggots. In reporting upon field 

 tests of insecticides for controlling San Jose scale, Dr. Smith states that 

 lime-sulphur washes have not gained in favor in New Jersey, though they 

 have fully held their own. He reports good results as being almost inva- 

 riably obtained when a miscible oil, such as scalecide, is used, and devotes 

 considerable space to the discussion of home made miscible oils. The some- 

 what extended evidence respecting the application of bands of carbolic acid 

 to trunks of trees is by no means favorable to this method of treatment. 

 Brief notes are given on some new materials which may possibly be used 

 as insecticides; namely, arsenate of iron, arsenate of lime and arsenate of 

 barium. 



About half of the report is deservedly occupied by an account of the ex- 

 ceedingly important work against mosquitoes done in 1907. Details are given 

 respecting methods and the amount of work accomplished in different locali- 

 ties. We regret that the author has not seen fit to incorporate in this portion 

 of the report a summarized statement as to what has already been accom- 

 plished along this most practical line of effort, so that one can, in a short 

 time, gain an adequate idea of the progress made in freeing New Jersey from 

 the blood-thirsty swarms of mosquitoes. One of the most interesting occur- 

 rences of the year was the discovery of the larva and breeding habits of 

 Culex perturbans, a species which up to last year had eluded the vigilance 

 of all Americans working upon the biology of this group.

Report on the Injurious Insects and Other Animals Observed in 

 the Midland Counties during 1907, by Walter E, Collinge, 58 

 pages. 

 This report gives summarized accounts of a large number of the more 

 important injurious insects, together with reports on insecticides and fungi- 

 cides. Experiments in controlling the gall mite on black currant, Eriophyes 

 ribis, show that spraying with the lime-sulphur wash is most effective. 

 Reporting upon a series of experiments for destroying all insects and other 

 injurious organisms inhabiting the soil. Prof. Collinge states that he has 

 obtained a fumigant designated as "Apterite" which will effectually rid the 

 soil of these enemies. This is presumably a proprietary material, as no clue 

 is given respecting its composition. The general appearance of this report 

 is exceedingly good, the letter press and paper being much above the 

 average. E. P. F.
