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.
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.
