er have been able to find anything like it since; neither have I learned whether it is common in other sections. SECRETIONS OF THE APHIS. The liquid ejected by the aphis, (plant louse,) when feeding or sucking the juices of tender leaves, and received by the ants that are always in attendance, is something like it; but in this case the bees were in attendance instead of ants. This mode of elaborating honey, although not generally collected by bees, perhaps may not be too much out of place here. Also, it may furnish a clue to the cause or substantiate some theory of honey-dew. These insects (_Aphis_) have been very appropriately termed "ants' cows," as they are regarded by them with the most tender care and solicitude. In July or August, when the majority of the leaves of our apple trees are matured, there is often a few sprouts or suckers about the bottom or trunk, that continue growing and putting out fresh leaves. On the under side of these, you will find the _aphis_ by hundreds, of all sizes, from those just hatched to the perfect insect with wings. All appear to be engaged in sucking the bitter juice from the tender leaf and stalk. The ants are among them by scores. (They are often accused by the careless observer of the injury, instead of the _aphis_.) Occasionally there will issue from their abdomen a small, transparent globule, which the ant is ever ready to receive. When a load is obtained it descends to the nest; others may be seen going and returning continually. Many other kinds of trees, shrubs and plants are used by the ants as "cow pasture," and most kinds of ants are engaged in this dairy business.[11] Would the bees attend on the _aphis_ for this secretion, (for it appears to be honey,) if the ant was not there first? Or if there were no ants or bees, would this secretion be discharged, and falling on the leaves below them, be honey-dew? If they were situated on some lofty trees, and it lodged on the leaves of small bushes near the earth, it would, with some authors. [11] The history of insects, as published by Harpers, gives more particulars on this interesting subject. These questions I shall not answer, at present. As for theory, I shall probably have enough before I get through, where I hope the subject may be more interesting.[12] [12] Since the foregoing was written, I have made some further observations on this subject. In August, 1852, I noticed, on
