MR. EDITOR:--About the middle of August, by invitation of Mr. Alfred Green, of Amesbury, a friend and myself visited his place to see the bees work on the Rocky Mountain bee plant. We arrived there about eight o’clock in the morning, and found the plants swarming with bees; one, two, and in some cases three bees upon the same flower. Mr. Green informed us that they were still at work on it, the day before, at seven o’clock in the evening. It was amusing to see them gather pollen from it while on the wing, the stamens extending so far out that they could not reach them after alighting on the flower. The plant was growing on a rather light soil, not highly manured, and stood from two to three feet high, branching out in all directions. Planted in the spring, it comes into blossom soon after the white clover disappears and continues until killed by the frost. If planted in the fall, as Mr. G. says it can be, it would blossom much earlier. I think this is the best plant to cultivate for bees, as it fills a vacancy, (in this locality) between the white clover and the fall flower. Alsike clover I have raised, commencing in 1860; and find that, on my soil, bees prefer it to white clover. But as it begins and ends blossoming at the same time with white clover, it is not of so much value for bees, as it would be if it came a month or so later. As the seed of the Rocky Mountain bee plant is valuable for poultry, and probably for swine and other farm stock, when made into meal, it would perhaps pay to raise it for the seed alone.

Well, Mr. Editor, I saw in the Bee Journal for July something concerning the injuriousness of the silk weed or milk weed. After reading the article it struck me that there was some of this weed in the vicinity of my apiary, and next day set about to search for it. On going out west, on the low ground on the prairie, I found ten flowering stems of this weed, and seven of the ten had bees fastened on them. Some of these bees were dead, and some still living, though they could not leave the flowers, being fastened in them by their hind legs. The bees seemed to have been gathering honey. Last Monday, as I was going to a neighbor’s, I saw one of these flowers, three quarters of a mile from my home. I stopped to see if I could find any bees on it, and found an Italian just alive. I am glad there are not many of this species of plants in this neighborhood. R. MILLER. _Rochelle, Ills._ [For the American Bee Journal.] Honey Dew.
