School instruction in entomology, E. J. Wickson, M. A. (pp. 

 .303-307). — By an a<-t of the California legislature apjuoved March 15, 

 1887, i)ractical eutouiology was included among the branches to be 

 taught in the public schools. The present article contains .suggestions 

 to teachers regarding methods of instru<-tion and abstracts from 

 re}>orts of school ollicers sliow ing how the law is being carried out. It 

 appears that ettorts are being nmde to give attention to this subject in 

 the schools of many localities, and that on the whole there is satisfa<'- 

 tory progress in the introduction of this new branch into the s<'hool 

 curriculum. There is great need of an elementary manual on economic 

 entomology as a guide to teachers and pujiils in «-oniuM'tion with oral 

 instruction and object lessons. 



Spray and hand treatment for the codlinu moth, C. W. 

 WooDWORTH, M. S. (pp. 3(>S-;U2). — Notes an<l tabulated data are given 

 for experiments in which Paris green (1 pound to 100 or 320 gallons of 

 water), London jiurpled jiound toSOcu- 100 gjillons of water), and white 

 arsenic (1 pound to 32(>, 4S(i, or 040 gallons of water) were s])ray<"d on 

 apple and pear trees three tinjes (in most ca«es) within 30 days after 

 May 3. During this ])eriod there was very little rain. The uu>st sat- 

 isfactory results w«'re obtained with Paris green, 1 j>ound to 100 gallons 

 of water, by which a saving of two thirds of the fruit which wcmld 

 otherwise have been injured, was ettected. The band treatment 

 destroyed less than half of the larva*, and then only after tiiey ha<l com- 

 pleted their injury to the fruit. Lists of varieties of [tears and apples 

 are given, classilied with reference Ut the amount of injury which they 

 received from the codling moth.
