Add to these Chickasaw, Bingham, Blue Plum, Italian Damask, Bleeker's Gage, Duane's 

 Purple, and St. Catharine, for drying, and you have all that are desirable. 



It is proper to add 

 that these notes are not 

 the result of my own 

 observations, solely. In 

 collecting material. I 

 have been greatly in- 

 debted to Dr. Ward 

 and Dr. Camak, of this 

 place, both for the re- 

 sults of their larger ex- 

 perience, and for their 

 kindness in supplying 

 specimens of nearly 

 everything which for 

 four years past, has 

 fruited in their fine col- 

 lections. 



Enclosed you will 

 find an outline of the 

 Horse Apple, which is 

 unusuallyfine this year. 



In flavor and COnsis- ^''^ -^'"•^« Apple.— Average size. 



tence it is more like the Rhode Island Greening than any other variety in my knowledge. 

 It is a good cider apple, also. 



A lady subscriber of this place has the Fastolif Raspberry, of which the flavor is very 

 well, but of the little drupes or carpels which compose the berry, only three or four swell 

 to each berry; the rest dry up and are abortive. The plants thrive well enough. Can 

 this infertility be cured, and how? If not, the variety is worthless. 



Two errors in the July number need correction. To destroy the wooly aphis, I direct- 

 ed the whole tree to be ivashed in soap-suds — not worked — which is nonsense. Again, 

 the stem of the Red June Apple, is from one-half to three-fourths of an inch long, and 

 not as printed, from one and a-half to three-fourths, which is incorrect. 



Yours very truly, TVm. N. White.

THE PHILOSOPHY OF THE DESTRUCTION OF PLANTS BY FROST. 



BY PROFESSOR LI.NDLEV.* 



The past winter of such extraordinary severity, has led to a good deal of speculation as 

 to the precise action of severe frost upon vegetation. As but little has been written upon 

 this subject, in this country, we have thought it might interest our more inquiring read 

 know the views of the principal European physiologists. Prof. Lindley gave, some
