bark, for an inch in diameter, came with it, — the space below

I should be very glad to fmd, that my explanation of this 

 matter is not the true one. For, when I became satisfied that 

 fire blight was not caused by an insect, and that it was not 

 a disease, but the result of cold, acting on the fluids of the 

 tree, I began to despair of the orchard I had so fondly com- 

 menced, with a fine selection. For I can scarcely hope, that, 

 at intervals of fifteen or twenty years, seasons may occur so 

 unfavorable, as to carry oft' our trees, despite of every care 

 we may use. But we may, nevertheless, do something, by 

 selection of soil, and planting in the lightest soils that the 

 nature of each kind will bear ; and still more may be done, by 

 seeking hardy kinds that make slow growth, and always ripen 

 their wood ; and by growing our thrifty kinds on slow-growing 

 stocks.

We can assure Mr. James, to whom we feel much indebted 

 for the above interesting account of his experience, with the 

 destructive blight of the West, that it is entirely distitict from 

 the insect blight, as described by Mr. Lowell, and Gov. Lin- 

 coln ; but, as we have no room now to discuss the matter, we 

 propose to take it up in another number. We will then en- 

 deavor, with the aid of Dr. Harris, to show the undoubted 

 character of the Insect Blight. — Ed.

The disease in potatoes has, for the last few years, been a 

 prolific source of discussion in our agricultural and horticul- 

 tural journals. As that subject has become rather stale of late, 

 not that the importance of the subject has decreased, but that 

 those discussions have not produced any definite conclusion 

 either as to the cause of the disease, or an acknowledged pre- 

 ventive, I would invite the attention of your pomological con-
