The New Launch.

The new launch, the "Frank Thomson," arrived in Cambridge yesterday afternoon. It is 50 ft. 5 in. long, 1. ft. 5 in. longer than the "John Harvard," but appears much larger owing to its greater breadth and higher freeboard. It draws less water than the "John Harvard" and is not so high, two very important attributes on a river like the Charles, where there are so many mud flats and where so many of the bridges are too low to pass under at high tide. It was used yesterday afternoon and proved much faster than the "John Harvard." It has a maximum speed of about fifteen and one-half knots an hour and will hold from twenty to thirty people. The old launch could not hold more than about fourteen people comfortably. The "Frank Thompson" is finished completely in mahogany.
