DEAR JACK: It is odd how names mislead. The calla lily is a calla, not a lily. The tuberose is not a rose at all. The strawberry and the blackberry are not berries. German silver came not from Germany, any more than did the Turkish bath from Turkey. French calf and Russian leather are both American. There is no wax in sealing-wax, and not a bit of bone in all the whalebone in the world. China-ware is made in our own country. Pinks are not all pink. Not every one called Black is a colored person; and how very many are called Wise who are not! Yours truly, M. E. L. WHO CAN ANSWER THIS? DEAR JACK: Like the Little School-ma'am's friend, Dorothy G----, I have been reading the "Life of Longfellow," and I found in it the following extract from his diary, which has puzzled me: "R. at tea. He gave us the following verse for finding on what day of the week the first of any month falls: 'At Dover dwells George Brown, Esquire, Good Christopher Finch and Daniel Frier.'" Now, can you, Dear Jack, or can some of your wise friends tell me how to discover on what day of the week the first of any month falls, by the aid of this couplet? Yours truly, M. W----. [Illustration] THE AGASSIZ ASSOCIATION SIXTY-FIFTH REPORT. AGASSIZ AND AUDUBON. In many respects the characters of these two great naturalists were alike,--and especially in their affectionate gentleness and mercy. Although, in the interests of science, both were led to destroy the lives of many animals, no men were more careful to avoid needless slaughter and unnecessary pain. It was Audubon who said, "_The moment a bird was dead, however beautiful it had been when in life, the pleasure arising from the possession of it became blunted._" This saying has become the motto of a large and rapidly growing society, organized in 1886, and known as the AUDUBON SOCIETY, for the protection of birds. This society, recognizing the increasing influence of the AGASSIZ ASSOCIATION, has sent to us a special invitation to co-operate in its work. The circular of the AUDUBON SOCIETY shows, first, the alarming rate at which our birds are being exterminated. It gives a series of startling facts; for example, "One New York firm had on hand, February 1, 1886, 200,000 skins," and it closes this paragraph as follows: "These figures tell their own story; but it is a story which might be known even without them; we may read it plainly enough in the silent hedges, once vocal with the morning songs of birds, and in the deserted fields, where once bright plumage flashed in the sunlight." The purpose of the Society is to prevent, as far as possible, 1. The killing of any wild bird not used for food. 2. The taking or destroying of the eggs or nests of any wild birds. 3. The wearing of the feathers of wild birds. THE plan of work is very simple.
