Spice Islands, and Eastern India, brought to the Bay of Panama, were to be transferred across the isthmus to the new settlement, and exchanged for the commodities of Europe. In Paterson's enthusiastic words, "This door of the seas and key of the universe will enable its possessors to become the legislators of both worlds and the arbitrators of commerce. The settlers at Darien will acquire a nobler empire than Alexander or Cæsar, without fatigue, expense, or danger, as well as without incurring the guilt and bloodshed of conquerors."

So 1,200 settlers set sail from Leith in July 1698, no doubt with a high hope and courage. In November the expedition arrived and established itself at a point of the coast still called Puerto Escoces, or Scotch Port, in Caledonian Bay, also named from the same event. "New Edinburgh" and "New St. Andrews" were founded, but the settlers soon got into difficulties. The climate was intolerable, and the project was opposed from the outset by the English and Dutch East India Companies, who were alarmed on the score of their own exclusive rights, while Spaniards and Indians were a perpetual menace. Broken down by these adversities the original settlers left the place, but were succeeded at once by another company which, after some successful fighting with the Spaniards, were compelled by the superior forces of the enemy to evacuate the settlements in the year 1700. It is possible that if this attempt at colonization had been made after and not before the Union of Scotland and Ireland it would have met with much less opposition in England, perhaps would have received government sympathy and support. In that case the isthmus would have been added to the British dominions, and a waterway might have been constructed under the British flag. It should be added that Paterson, who had personally surveyed the isthmus, positively declared that the construction of a canal was a feasible undertaking.

During the eighteenth century, though surveying was carried out in many parts of the isthmus by European engineers, the project of a canal was never seriously taken up. It may be remembered that in 1780 our own Nelson was at Nicaragua, annexing the lake and getting control of the interoceanic route in this region, but doing little more than injuring his own health. With the nineteenth century, however, events began to move at the isthmus. The great scientist, Alexander von Humboldt, spent the first few years of the new century in Mexico and Central America. In his "Political Essay on New Spain" he described the impervious isthmus, "the barrier against the waves of the Atlantic," as for ages "the bulwark of the independence of China and Japan."

The absence of any water communication at the isthmus between the two oceans has indeed had highly important political and economic results. It kept East and West far asunder. It removed the west coast of North America from the colonizing rivalries of the Old World. England and the United States seemed for long ages only semiconscious of their territories on the Pacific which were awaiting colonization. Even in recent times very few emigrants from Europe, who went out with the intention of going far west, penetrated much further than Chicago or Manitoba. Population and industrial enterprise were concentrated in the east of Canada and the United States, and have only begun within modern times to move effectually westwards. England was indeed so indifferent about her territories along a far coast, which could be reached only round the Horn or by an almost impossible land-transit, that in the settlement of the Oregon boundary in the middle of last century she accepted a Canadian frontier-line much further north than would otherwise have contented her. She had at least as good a right to California and the territories to the northwards as the descendants of her revolted colonists. The absence of a waterway at the narrow lands secured to the United States and to England their expansion westwards, but imposed on the westward movement a very slow and gradual pace. One result of the new canal will be a very rapid development of these Pacific slopes, especially those of British Columbia.

The effect on South America of this complete severance of East and West has also been very important. The republics on the Pacific have been sheltered as much as possible from European influences. Immigration has been naturally restricted, the population, especially that of Chile, kept free from negro admixture, and the development of the countries effectually checked. The opening of the canal will, of course, have a contrary effect all along these lines.

But, to return from this digression, Humboldt described six routes in Central America where a canal would be practicable, including that which was afterwards adopted at Panama. He investigated and discussed many physiographical questions in connection with the subject. There had arisen a general belief that the level of the Pacific was much higher than that of the Atlantic, and that a sea-level canal would therefore be impossible. Humboldt declared against this theory. But it is curious to find him favouring the idea that the construction of a tide-level canal might have the effect of diverting the Gulf Stream from our shores, and thus making the climate of our British islands much more rigorous and inhospitable.

The researches of Humboldt in the West Indies and Central America much interested the scientist's great fellow-countryman, Goethe. A passage from Goethe's "Conversations with Eckermann" is worth quoting as an example of prophecy wonderfully fulfilled:—
