Like the _Holland_, this boat can move on the surface of the water or
dive beneath it at will. But this vessel is arranged with a view to
remaining under water for a whole day without causing any inconvenience
to the inmates.

This is not the only kind of curious vessel that has been built lately.

A ship has been devised, and is said to be actually building in Toronto,
Canada, which is intended to roll across the Atlantic Ocean.

The description of this boat says that it looks exactly like a long
gas-pipe. It has neither masts nor funnels, but is made of two
cylinders, one inside the other.

The outer case revolves, and is fitted with paddles to propel the vessel
through the water. It is claimed that by this means a very high rate of
speed can be secured.

The inner cylinder is so arranged that it remains stationary, and in
this are the cabins, staterooms, and engine-rooms. Both cylinders have
openings at the ends, and it is through these openings that the fresh
air is communicated to the staterooms.

Between the inner and outer cases are compartments for the cargo, which
revolves with the outer cylinder.

It is claimed that this ship will make the trip from Liverpool to New
York in forty-eight hours.

The boat is to be completed in a few weeks, and then we shall see for
