W. Prentiss D. and Others.—A mistake was made in the scale of the plans for making a sail-boat in Young People No. 66, owing to the failure of the artist to allow for the reduction of his drawing. As it stands, instead of one inch equalling one foot, the general scale is a scant nine-sixteenths of an inch to one foot. That for figures 3, 6, 7 is one-eighth of an inch to one foot, and that for the completed drawing is nine-thirty-secondths of an inch to the foot. This would give a boat twelve feet long.

J. E. B. B.—No such advertisement ever appeared in any paper, for no such offer was ever made by the United States government.
Willie F. W. and Rosa M. B.—Some numbers of Harper's Young People, Vol. I., can be obtained of the publishers, but not a complete set.
Starry Flag.—United States twenty-cent pieces were coined in 1875, and also during the three following years. The largest coinage was in 1876, and the smallest in 1878.
