 and made use of, the centres of civilisation will probably lie very much where they lie now; and here the congested populations will have found that they can no longer tolerate the waste of a neglected ocean. As we push outward from the centre of the continents, the seaboard will have to be utilised and extended. There is nothing to daunt the engineers of a hundred years hence in the project of erecting on the sea a vast floating city, fully as convenient as the present cities of terra firma, and, while vastly more healthful, quite substantial enough to resist storm and every motion of the sea, except the tides on which the city will rise and fall—tides which will no doubt furnish the motive power of many conveniences in ocean cities.

There are great advantages in a city thus founded, as compared with those we at present inhabit; and we certainly shall not be able to neglect them. There will be no particular reason for economy of space or for insalubrious overcrowding (since the sea has no landlord), and breadth would make for stability as well as for convenience. Urban traffic will employ an entirely new light vehicle, the skimmer. It has been mentioned as a thing beyond doubt that the ships of a hundred years hence will no longer float in the sea, but ride on its surface, thus evading both the instability and the resistance at present so troublesome to
