never dreamed of changing. One of the conditions was, and is, that her patroness shall provide a husband for her. Often enough, also, the child of such a protégée succeeds to her place when old enough, and thus very pleasing relations are established between families of different status. . . . The practice of adopting girl-children to train as servants becomes more and more common as slaves become scarcer. . . . A class of domestic servants is being formed which, in due time, will replace the slaves. But transformations of the sort are very, very slow in the East. Meanwhile the process is very disagreeable, even shocking, to Moslem housewives, and it is not at all surprising that they should pay heavily and run some risk to obtain a negro who is all their own."
Lake Beaches.—In his discussion of the beaches and their correlative moraines of Lake Erie, in the American Journal of Science, Mr. Frank Leverett shows that the belief of geologists now is that the phenomena do not demand a submergence of the land during the closing stages of the Glacial epoch; that, instead of a depression, there was a greater altitude than in the earlier part of the period; and that the result of investigation has been to reduce the noteworthy lakes connected with the closing stages of glaciation in Ohio to the one bounded by the beach lines that were recognized by the Ohio Geological Survey. The examination of the phenomena in detail leads to the conclusion that Lake Erie, in its earlier stages, was but a small body of water, its size being conditioned by the position of the retreating ice-sheet and by the height of the western rim of the basin it occupied.

According to Dr. R. W. Shufeldt's observations of the Navajo belt-weavers, curves are never found in the figure-patterns on the belts or blankets, but horizontal stripes, diagonals, and the lozenge are interwoven with a variety that appears to be almost endless in the matter of design. The leading colors used are red, brilliant orange-yellow, a blue, and by combination a green, and black, white and gray.
