ICE BOAT RACES ON THE MUEGGELSEE, NEAR BERLIN.

The interest in sports of different kinds is increasing considerably in
the capital of the German Empire. Oarsmen and sailors show their ability
in grand regattas; roller-skating rinks are very, popular; numerous
bicycle clubs arrange grand tournaments; and training, starting, trotting,
swimming, turning, fencing, walking, and running are practiced everywhere.
As this winter has been quite severe in Germany, first class courses have
been made for ice boats. Ice boat, races are well known in the United
States, but are quite novel in Germany; at least, in the neighborhood of
Berlin, as they have been known only on the coast of the Baltic Sea.

[Illustration: ICE BOAT RACES ON THE MUEGGELSEE, NEAR BERLIN.]

These vessels are quite simple in construction, the base consisting of an
equilateral triangle made of beams and provided at the corners with
runners. The two front runners are fixed, but the one at the apex of the
triangle is pivoted, and serves as a rudder. The mast is on the front
cross beam, and between the front cross beam and the side beams sufficient
space is left for the helmsman.

The annexed cut, taken from the _Illustrirte Zeitung_, shows a race of the
above described ice boats on the Mueggelsee (Mueggel Lake), near Berlin.
It will be seen from the clumsy construction of the boats that the Germans
have not yet learned the art of building these vehicles.
