the best American apples to-day, as well as their other fruits, are those 

 which have originated in the country as seedlings, and which have at the

In conclusion I would hke to take this opportunity of expressing my 

 thanks to Mr. C. P. Lounsbury, Cape Government Entomologist, the Cape 

 Orchard Company, Mr. Herbert Ingle, and Mr. R. A. Davis, Horticulturist 

 to this Department, for the valuable information and assistance which 

 they have rendered me in the carrjdng out of this investigation.
