Thus it is evident, that were the passage over the North Pole open (p. 108) and practicable at all seasons, but which it is not, the route by it would be so much shorter for every part from Europe to the ports in Asia and in America, situated on the Northern Pacific, as to be vastly preferable; but when it is recollected that this passage can only be open for a very few months in the course of the year--and also considering the winds and the weather which, during that brief space of time, would certainly be met with in the northern route, and the utter impossibility that there would be of procuring any assistance in that route, should accidents occur,--it is clear, that vessels would almost as speedily, and certainly much more safely, run over the distances by the western route, even to the places more near; while, as regards those which are more distant, there can and need be no comparison drawn. It will also from these references be observed, that the distances to all the eastern parts of Asia, and the north-west coast of America, are, with a very few exceptions (in these, too, the distances are nearly equal), nearer than the distances would be, either taken by the Cape of Good Hope or Cape Horn, the only routes always open; while, considering the winds and the seas which are met with in either of these routes, it is plain that ships would run over the distance by the western route through central America, even to the most distant parts in eastern Asia that have been adverted to, sooner and much easier than they could do by either of the former. The saving of insurance alone in the route by the mild tropical climates, and also of wear and tear in ships by the same channel, compared to what all these would amount to in the navigation by the other routes, to say nothing of the saving of time in voyages, would be objects of great importance to commercial and nautical men.
