Between 4 and 4.30 the "Congress," having been raked fore and aft for nearly an hour by the "Merrimac," was forced to surrender.
Distinctive feature of the genus is the great fore-and-aft length of the penultimate premolar in both jaws.
These models flew in a haphazard sort of a way, it being found exceedingly difficult to confer on them the necessary degree of stability fore and aft and laterally.
This consisted of a small elastic aeroplane placed aft or behind the principal aeroplane which is also elastic. The two elastic aeroplanes extended horizontally and made a slight upward angle with the horizon, the angle made by the smaller aeroplane (the rudder).
Models on the aeroplane screw type may be propelled by two screws, one fore and one aft, rotating in opposite directions; and in the event of only one screw being employed it may be placed in front of or behind the aeroplane.
