be confounded with this injury. J. B. Smith has treated of 

 the same insect,* and recommends potash in the form of 

 kainit as most satisfactory, acting both as a fertihzer and in- 

 secticide. For the serial forms, whale oil soap is recom- 

 mended. Later, he repeats E. F. Smith's recommendation of 

 tobacco for underground forms. 



''The peach tree borer has also been treated by J. B. 

 Smith, f who recommends mechanical means, wrapping the 

 base of the tree with upright straw or newspaper, to prevent 

 oviposition, or destructive means by pouring diluted kerosene 

 emulsion around the base after removing the top soil. 



" Alwood, of the Virginia station, related at the meeting of 

 the economic entomologists in November, that painting the 

 trunk with ordinary white paint to which a little Paris green 

 is added is a perfect protection. Of course, all these applica- 

 tions must extend for a depth of at least six inches below the 

 soil to be effective. 



''Apple insects have received the usual amount of atten- 

 tion. Spraying for the codlin moth larvae was practiced at 

 several stations, and uniform success is reported. There is no 

 longer a doubt that we have a safe and reliable remedy for the 

 injuries done by this insect. 



"Weed has studied the oyster-shell bark louse (yMytilaspis 

 po7noriH7i) and the scurfy bark louse (yCJiiotiaspis fiirfiiriis^ and 

 recommends J scrubbing trunk and branches with carbolic 

 mixture, i pt. crude carbolic acid to 7 parts of a solution made 

 by disolving i qt. soft soap or yi, lb. hard soap in 2 quarts 

 boiling water. 



"The buffalo tree hopper {Ceresa bubahis) has proved in- 

 jurious in Ohio by puncturing twigs and branches for oviposi- 

 ting and for this, the kerosene emulsion, used after the young 

 insects have made their appearance, is recommended. 



"In New Jersey, muriate of potash in water, used to wash 

 tree trunks, has proved effective in destroying the scurfy scale. § 



"Apple plant lice were also reported on by Hillman, || who 

 recommends for the leaf lice the standard preparations of 

 kerosene and tobacco, and for the root lice {Schizo7ieura lanigera)
