We publish in this number an interesting letter from Mr. Rivers, of Sawbridgeworth, England. Mr. R. suggests "biennial autumnal removal," as a remedy for the "black blight." The very worst case of blight - "fire blight," as it is called here - that we remember to have seen, was in a plantation of Pears imported the year before from France, and, of course, just in the condition that "biennial removal" would put them.

IN regard to the difficulty of growing Apricots in the open air, which Mr. RivERs supposes is occasioned by early frost, it may be well to remark, for the benefit of our English readers, that the difficulty is not so much on account of spring frosts, as the weevil, or cur-culio, which deposits its eggs in the young fruit, causing it to fall prematurely. This is the great enemy of our Plums and Nectarines, as well as Apricots; and we wish they were banished to the other side of the Atlantic, so that our English friends might have the privilege of studying their habits, while we enjoyed the fruit.
