interest and importance to last year’s account of a above insect. 
This experience has already been made public in an article pub- 
lished in the “ Rural New Yorker,” and reproduced in the “ Rural 
World” of St. Louis. I am pleased to know that the views there 
set forth receive the indorsement of such an experienced 
practical man as Mr. Geo. Husmann, the well known grape ai-

the last named journal.

grape-vine ( Vitis vinifera) have, in the end, proved valueless when 
introduced and cultivated in the eastern half of the United States. 
The majority of them grow well at first, and a few excep pork 
cases might be mentioned where some of them, such as the 
Hamburg and Chasselas, have even -fruited succe 
years, especially when isolated or trained south walls;
