From Arabia, coffee, gums, perfumes and pearls come. At Aden I was told that the best Mocha coffee could be got for one shilling (or 24 cts.) per lb. In large quantities I think it can be got still cheaper. I should think precious stones (sapphire, jasper, &c.,) gums, coffee, cocoanut oil, cinnamon oil and pearl would pay best, perhaps also ivory and ostrich feathers. At Aden I found some large wheat, but kinds were mixed, or else the variety is not a fixed sort. This portion of the world produces little or no grain besides rice. I have obtained seeds of a number of flowering plants and trees, some of which I know yield honey, and others that look as though they might were there bees to gather it. We expect to reach Singapore to-morrow forenoon. I will take the first steamer for Batavia, which will likely leave in a day or so. FRANK BENTON. For the American Bee Journal. Cause of Bee Cholera or Dysentery. G. M. DOOLITTLE. I have noticed in several articles a statement quite similar to this, which is taken from Mr. James Heddon’s article in the February number of the _Bee-Keepers’ Instructor_: “Every bee-keeper of experience who lives in our northern latitudes has witnessed enough to know that cold or confinement, or both, do not _cause_ bee cholera or dysentery.” Now, I claim the title “bee-keeper” (whether of experience or not I dare not say), and live in the “northern latitudes,” yet I cannot be one of the number above styled as “_every_,” for I believe confinement _does cause_ the so-called dysentery, and hope to so clearly show it in this article that you will so acknowledge also. First. I once produced dysentery (I do not believe this is a disease, but merely an accumulation of the feces) in its worst form, the latter part of June, by confining a lot of bees to the hive for 10 days. A frame of brood was taken from the hive with the adhering bees, and also a frame of honey with the bees which were on that, and placed in an empty hive to form a nucleus, the bees being confined to the hive for three or four days, when the entrance was opened in the evening. Early the next morning there came on a cold storm and bad weather ensued, so the bees could not fly for six more days. On the tenth day the sun came out, and the bees from these nuclei (7 in number) were so loaded that they could scarcely fly. An examination revealed that they had eaten on an average about 2 lbs. of honey in each nucleus. Nuclei made but a few days before, which had flown 2 or 3 times before the bad weather, were not eager to fly, and showed no signs of dysentery, neither did our full colonies; nor had they eaten an undue amount of honey. The trouble here was evidently confinement, which caused the bees to worry and thereby consume an undue quantity of food, thus producing a necessity to void the excrement, or dysentery, if you please to call it so.
