Honey-dew is said to be a source from whence large collections are made in some places. When or where it appears or disappears is more than I can tell. I have seen the accounts of it, but accounts I have learned to doubt until I find something corroborative in my own experience. I find too many errors copied merely because they happen to be in company with several truths. Huber discovered many important truths, and has given them to the world; too many writers take it for granted when two points of his are true, the third _must be also_. It is no proof that there is no such article merely because I never discovered it. In the many fruitless endeavors that I have made to get a view of this substance, it may be I have lacked close observation; or possibly there is none showered upon this region; or I may have failed to bring my imagination to assist me to convert common dew into the real article. SINGULAR SECRETION. I once discovered bees collecting a secretion unconnected with flowers; but was not honey-dew, as it has been described. I was passing a bush of Witch-hazel, (_Hamamelis Virginiana_,) and was arrested by an unusual humming of bees. At first I supposed that a swarm was about me, yet it was late in the season, (it being about the 25th July.) On close inspection, I found the bush contained numerous warty excrescences, the size and shape of a hickory-nut. These proved to be only a shell--the inside lined with thousands of minute insects, a species of aphis. These appeared to be engaged sucking the juices, and discharging a clear, transparent fluid. Near the stem was an orifice about an eighth of an inch in diameter, out of which this liquid would gradually exude. So eager were the bees for this secretion, that several would crowd around one orifice at a time, each endeavoring to thrust the other away. This occurred several years ago, and I never 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.
