In some one of the points mentioned, and most probably from Lake Managua to Rialejo, or from Lake Nicaragua to the Gulf of Papagayo, the best line for a communication between the Atlantic and the (p. 099) Pacific will be found. The shores of Lake Nicaragua are tolerably well cultivated, and it has several harbours. Numerous streams flow into it from all sides, but particularly from the north. The river St. Juan is a considerable stream--as large, say the Spanish writers, as the Guadalquiver in its lower course. In a distance so short, a canal, fit to bear ships of the very largest tonnage, could be cut, at certainly no very heavy expense; say, at the rate of 300,000_l._ for 10 miles. Even if the river St. Juan should not be found to be navigable, and that it might be most advisable to cut a canal along its banks, from the Atlantic to the lake, the distance is not very great (45 or 50 miles), and the country presents no insuperable obstacles to it; on the contrary, it is believed to be easy of access. This distance might be cut for 675,000_l._--a small sum even joined to the other, when the immense object to be attained is considered. The choice of position, after considering attentively every point, will remain between Chagre to Panama, and between St. Juan and Nicaragua to Rialejo, as to which is the best line for a water communication; for it is pretty clear that the lines to the eastward and to the southward of Panama, narrow although the neck of land certainly is in these parts, can only be looked to as points for a speedy road communication in some, and for small craft in the others.

The jealousy of the government of Spain formerly sealed up every possible line of communication between the Atlantic and the Pacific, in all the places mentioned, from the rest of the world; and it is probable that the jealousy, and also the poverty and inability of the new governments lately started up in these parts may continue to do so, if they are allowed to do so, or if they remain unaided in the enterprise by foreign capital, and not be impelled thereto by foreign, but particularly European influence. A glance at the map of these parts of America, and at a map of the world, and a moment's reflection and consideration bestowed on the great interests that depend upon it, that would be laid open and connected by such a communication, is sufficient to show the prodigious benefits which would therefrom flow to the human race, and especially to the governments and the (p. 100) people of North and South America, and those fine but comparatively poor and miserable portions of this globe. The treasures and the labours of nations would be well bestowed in completing such an undertaking. Laying open such a communication would do more to people, to cultivate, and to civilize the world, than any other effort--than all other efforts made by the world at large, when combined and brought together. No nation in the world is so deeply interested in seeing a proper communication through the best of the channels pointed out laid open, as Great Britain; and no other nation could so well undertake it as she can. The immense empire which is rising under her flag in New Holland; the large territory which she would thereby bring within the sphere of cultivation and civilization on the west coast of North America, to the north of Colombia River, where both the climate and the soil are good; the vast and important trade which she has with China, and may yet have with all the beautiful islands in the Pacific, with Japan, and with all Eastern Siberia; and the very great trade which she has, and would have with all the shores of America on the Pacific,--all render the attainment of the object contemplated peculiarly her interest, and peculiarly her province to undertake, support, complete, and protect, in a way and on a scale worthy of the intelligence, the enterprize, the strength, and the resources of her government and her people. The number of people, and the traffic which it would in time add to the present trade and population of the world, exceed the powers of calculation.
