While in Newburgh recently, our attention was arrested by the peculiar appearance of the Oats, which seemed to be very black. A close examination revealed the startling sight of millions of the brown Aphis, the plants being literally covered with them. On inquiry we learned that nothing of the kind had ever been seen before. Oats look bad enough, the straw being very short and the heads small. The drought has, no doubt, had something to do with this, but we think the Aphis has done its full share. At the ferry we met a person who had a large vial full, and who desired to know what they were. Mr. Downing then informed us that he had just returned from Connecticut, where he had seen the same thing, but without noticing what they were. The farmers, however, seemed a good deal alarmed, and we think with good reason; for if the Aphis is to occupy in force this new field, there can be little doubt that the Oat crop will be reduced fully one-third. It is a matter which requires the farmer's serious consideration. The means used by the gardener for their destruction will have to be used by the farmer on a large scale.
We should be glad to know in how many localities the Aphis has been thus seen.
