River Depths.

An ingenious apparatus for ascertaining the depth of rivers and smaller streams has recently been successfully tried on the Elbe. It consists of a curved arm, hinged at its upper extremity, and of a length sufficient for the lower curved portion to trail on the bed of the stream. The greater the depth of the stream the more will the arm be inclined, and hence, by suitable recording mechanism, the depth can be automatically registered.

The proper place for undressed kid Is in the bath-tub.
