For apple and pear trees, when stripped of foliage, 

 the ordinary garden 'pump will be sufficient. 



To Nurserymen : In a flower garden in this city we 

 found a rosebush that was nearly covered with a species 

 of this scale insect. We applied the sulphur and lime 

 solution in July, but it had little effect. On the i5th of 

 September the stem and branches were covered so thick 

 that they appeared as if whitewashed. We applied the 

 Codling Moth Wash and in a few days the scale was 

 destroyed. We have called the attention of several per- 

 sons, and had them examine the residue left on the stem 

 and branches. Among those who examined was I. N. 

 Hoag, Esq., Secretary State Agricultural Society. All 

 agree that the destruction of the insect was complete. 



At the Los Angeles Horticultural Fair (1879), we met 

 Albert S. White, Esq., of Riverside, San Bernardino 

 County, and requested him to try some experiments by 

 applying the Codling Moth Wash on the scale found on 

 orange trees. We forwarded to him a package of the 

 preparation, and have received the following report: 



RIVERSIDE, Nov. 3d, 1879. 

 Messrs. COOKE & SON 



Gentlemen : I have given the preparation sent me a 

 thorough trial, and find that it makes very short work of 

 the scale bug. Yours, truly, 



ALBERT S. WHITE. 



We are under obligations to C. H. Dwinelle, Esq., of 

 the State University, Berkeley, for the following commu-

 insect :
