will gather upon that and leave the others unmolested. In proof of 

 this assertion, I quote the two following passages from among a num- 

 ber of similar ones, the first from the Eeport of tlie Winter Meeting 

 of the Fruit-growers" Association of Western New York, Jan. 23, 

 1867, the second from the American Journal of Horticulture, Sept., 

 186?, p. 163: 



"F. C. Brehm thinks the Clinton the best vine to draw rose-hugs 

 from other vines, and keeps one in his garden for that purpose." 



"When I saw a paragraph in a Horticultural Paper, advising 

 grape-growers to keep one vine of the Clinton in the garden for the 

 use of the rose-bugs, I thought it merely a feeble joke; but experience 

 teaches me that it is no joke at all. I have a Clinton vine at a little 

 distance from a dozen other kinds, and its leaves are entirely riddled 

 by the Rose-bugs; while I have not found six bugs on the other va- 

 rieties, and none at all on the roses. I pity the want of taste dis- 

 played by the bugs, but am glad to find that the Clinton is good for 

 something. Since writing the above, I have found bugs in abun- 

 dance on the Franklin: but that only strengthens the case; for the 

 Franklin is much like the Clinton and just as worthless."

INSECTS, INFESTING THE GRAPE.— On the Root. 

 CHAPTER IV. — The Grapk-root Borer. {^Egeria polistiformis, Harris.) 



This insect, which strikingly resembles the common Peach Borer, 

 {jEgeria exitiosa. Say,) in all its stages, both in size, in shape, and 

 in the general style of its coloration, was observed fifteen years ago 

 by Dr. F. J. Kron, of Albemarle in North Carolina, to be very 

 destructive to the cultivated grape-vines there. I see from the 

 Monthly Reports of the A(jrictiliural Department for 1867 (pp 329 — 

 330,) that Mr. H. J. Krone, of the same place — who may probably be 

 a relative of Dr. Kron's, though his name is printed with an E at the 

 end of it — "gives discouraging reports about the destruction of grape- 

 vines in that region" by this same Borer in 1867. In the same 

 Monthly Report it is stated that "a correspondent in Cincinnati writes 

 that a new enemy has attacked the grape-vines in that vicinity, and 

 describes its work as similar to that of the North Carolina yEgeria 

 polistiformis." Lastly, in the summer of 1867, Mr. C. S. Jackson, 

 of Danville, Kentucky, sent me specimens of the larva of this very 

 same insect, along with pieces of the grape-vine roots on which it was 

 operating. "Here in Central Kentucky," he says, "I have noticed, 

 for a year or two past, spots throughout the vineyards suffering from
