from the casks without stirring ; therefore, the trees washed 

 from the liquid taken from the bottom of the casks stood an 

 application about three times as strong as necessary ; how- 

 ever, they came out all right. The mistake was rectified, and 

 the experience noted for future use. 



Rksult. — D's thorougli application was successful in every 

 respect. It cost him .tOOO, but his orchard is clear of San Jose 

 scale. 



E owns an orchard containing seven thousand trees, for 

 which he paid .1!82,000 in 1879. In October, 1881, it was seri- 

 ously infested by the San Jose scale. In November he bought 

 seven tons of concentrated lye, and commenced work. About 

 new-year his neighl>or condemned his work as being so 

 thorough it killed all his trees. He wrote me what he had 

 done. I advised him to " go on as he had been doing,'' and in 

 a few days after visited his orchard. The work Avas completed 

 as commenced. I visited the orchard on the thirty-lirst day 

 of March following (1881) ; every tree was in bloom, and but 

 few of the scale insects in a healthy condition. I asked the 

 owner at what value he estimated the result of his persever- 

 ance and th()i'()Ui:li work. He answeri'd : '* Last October. I 

 would have sold the orchard, l)ugs and all, for $15,000. At a 

 cost of a little over $1,200, I have conquered the ])Ugs. Now, 

 sir, you cannot Imy it for $40,000. and you can so inform your 

 friends.'' 



Moral. — Follow E's exani])le. 



First-class material to make the solution and thorough 

 application will destroy the scale insect witliout fail. 



Do the work as recommended, thoroughly, and the bugs 

 must go.
