three 'Rovers' for the cost of two ships of the 'Shah' type. In discussing the propositions laid down by Mr. Barnaby.

By avoiding the too prevalent idea that every man-of-war must be able to steam at an extreme rate of speed, we may be able for the same expenditure to build a much larger number of vessels.
Mr. ChildersIn his speech of 1869, Mr. Childers enumerated among the vessels of the navy, efficient for the protection of commerce, twelve corvettes of the 'Blanche' class, with a speed of 13 knots, and carrying 6½-ton guns, two of the 'Druid' class, with the same speed and armament, twelve gun-vessels with a speed of 11 knots and with 6½-ton guns, and seventeen new composite gunboats, with a speed of 10 knots and 6½-ton guns.
