MR. EDITOR:--I have at last caught the chaps that rain down what is called honey-dew. In localities where the common willow grows, I found the most. On the Missouri river bottom, which is literally covered with willows, I find in June and July they are covered with small insects, which at a certain age get wings and fly off in large swarms, going for miles. Sometimes they will stop in the air, over some trees, and fly around in a circle for an hour. If you get them between your eye and the sun, you will see them discharging the so-called honey-dew. They will stop in one place, the same as gnats or mosquitoes, which you have often seen about as high as a man’s head. Now, if any person really wants to test the correctness of this, let him go to a willow grove and he will find those insects (or willow lice) just before sun-down; and getting the willows between him and the sun, he will see them rising from every part of the tree, in small squads, and collecting till they form a large swarm. Then they will be seen discharging continually a fluid which resembles a fine sprinkle of rain. I have often seen those same insects discharging a fluid on a limb, where they were hatching; and then saw large ants, wasps, and yellow jackets working on it. And I often wondered how it got on the very tops of the trees, where no insects were to be found. I think this observation will settle the matter about the origin of honey-dew. Bees have done very poorly here until now. The golden rod is in full bloom, and the bees are doing well. H. FAUL. _Council Bluffs_, Sept. 6, 1870. [For the American Bee Journal.] Caution.
