I infer it does not uttack nut trees nor Jajjan persimmons. By referring 

 to our books, I Unci that in the spring of 1887, we ordered of John Eock, 

 8an Jose, C'ala., a quantity of Kel ley's Japan plums. These were 

 shipped us by order of John Eock from 8tark Bros., Louisiana, Mo. 

 They were received in unsalable condition so that they were not sold by 

 us but trenched out in nursery rows to recover. They never did recover, 

 but stood in the nursery two or three years and were dug up and burned, 

 and my recollection is they were infested with an insect and think it- 

 very probable that it was introduced in our nursery in that way. We 

 wouhl prefer that our name would not be published in connection with 

 this pest, as we realize it Avould ruin our business. We also realize the 

 danger of distributing any stock infested with it, and have since receipt 

 of your letter destroyed over $1,000 of young iftirsery stock, fearing, 

 possibly, it might have been exposed to the same insect. And, hereafter, 

 will make arrangements to have grown for us such stock as is liable to 

 the attack until we get rid of it — and grow only that free from it. * * 

 Thanking you kindly for calling our attention to it and esteeming 

 any information or assistance you can render us in connection therewith. 



I am very respectfully, 



rloHN R. Parry.

Dear Sir : — 



I have your long and satisfactory letter of the 25th inst. If you 

 succeed in more positively ascertaining how the scale reached you, I shall 

 esteem it a favor if you will notify me. In consideration of your intelli- 

 gent appreciation of the situation and your promise to avoid further 

 shipments of infested stock as well as to make every elfort to destroy the 

 insect in your nursery, it will l)e best, and most in act-ord with my own 

 desires, for the department to say nothing in print regarding the means 

 by Avhich this insect has l)econie distributed from your nursery for the 

 present at least. No particular good could be accomplished by it, in 

 view of your promise, though ultinuitely the historic fact will have to 

 be recorded. I shall be glad if you will keep me posted as to the result 

 of your operations against the insect. 



Yours very truly, 



C. \'. Piley, 



Entomoloifist.
