Few articles meet with a readier sale or more promptly remunerate the
inventor than the class of inventions adapted to the use of children
either in their school life or in their amusements. One of these
useful little novelties is shown in our engraving. It is a slate
washer, consisting of two pieces of metal stamped up so as to form a
holder for the sponge at the top and the cloth drier at the bottom.
They also form a tubular receptacle containing a supply sponge, which
is moistened by removing the corks at the ends.
This invention was recently patented by Mr. Jacob A. Smith, of Salem,
Ohio.
