Mr. Tegetmeier gave a lecture on Thursday at the Zoological

Gardens on carrier-pigeons, in which he said that they are being trained every where in Germany to keep up communication between the fortresses and the neighbouring towns in case of a siege, and that they had just been thought of for light-ships, so thatin case of need the light-ship may have the means of letting the nearest port know that it is in need of any special succour. The idea is an excellent one, if the birds can be trained to bear up against any storm of wind and rain or snow, drifting them in the direction opposite to that of their proper course. If not, the experiment might fail for the first time exactly when human life most depended upon it. Why is no attempt made to domesticate fishes? Carrier-fishes could swim, far beneath the stormy surface of the sea, and take their message into port through the most violent hurricanes with- out molestation by the elements.
