OF one mile will be represented by a space
about one-sixteenth Of an inch long. There

One of the Berlin papers tells Of a new
device for catching behring's. A German in
ventor places a microphone I'm a metal

meets the submerged microphone (Which
greatly increases the volume OF small
sounds) TO an ordinary receiver, with
which one listens 10 what is going on In
