Near Barbacoa station the eye of the traveller, that has hitherto revelled in the voluptuous beauties of nature, rests with pleasure on a splendid trophy of human industry, an iron bridge, 600 feet long, which spans the River Chagres at this point. It was on one of the Cerros, a little west of Barbacoa, that Vasco Nuñez de Balboa first beheld both the Atlantic and the Pacific oceans at once, and, regarding his stand-point in the Isthmus as a mere handful of earth, may have imagined himself a conqueror, whose glance comprehended both worlds.

The last portion of the line, as we near the Atlantic side, passes over vast swamps, which rendered the construction of this portion of the road exceedingly difficult and very expensive. Aspinwall itself moreover, the terminus of the Inter-oceanic Railway, lies on a small island, two-thirds of the surface of which is morass, and covered with tropical marsh vegetation. This station was selected, notwithstanding its

very unwholesome climate, chiefly because the roadstead of Limon Bay furnishes a safe anchorage in all weathers for vessels of even the largest size.

This small island, only 7000 feet long by 5800 wide, which was first named from the immense quantity of Hippomane mancinella, a tree with a very powerful poison, that is found on it, and is now called "Isla de Manzanilla," was formally made over by the New Granada Government to the American Company at the beginning of the works in the year 1852, and was used by it for the new city, as also for the erection of warehouses, &c.

Aspinwall, or Colon, as it is sometimes called, numbers at present some 1500 inhabitants, of whom 150 are North Americans and English, the rest negroes and mulattoes. The little town, with its neat frame-houses and clean cottages, involuntarily reminds one of the new settlements in the North American States. Here, besides the residences of the officials, are the warehouses and workshops of the Company. In the latter about 700 workmen are employed, while four schooners maintain uninterrupted communication between Aspinwall and New York, for the purpose of providing for the various wants of the crowded establishment. Even the very provisions are imported from North America. The resident director, Mr. A. J. Center, received me with the most hearty welcome, and during my entire stay continued to display the same kindness and interest, which he manifested from the moment he received my letter of introduction.

In Aspinwall the climate has within the last few years become more salubrious than at the period of the first colonization, when "Chagres fever" acquired a gruesome reputation, and no resident who stayed above two months in the place escaped the attack of the fever. Even mules and dogs could not escape the universal malaria. However, to this day a lengthened residence on this marshy soil is not unattended with danger, although the miasmatic poison has undoubtedly lost much of its virulence. The negroes longest resist its dangerous effect, after whom come the coolies, then the Europeans, while the Chinese are invariably the earliest attacked.[157]

On 23rd June, about midnight, I left Limon Bay in the steamer Medway. Having been committed to the charge of her captain by the kind attention of Mr. B. Cowan, the English Consul in Aspinwall, I found myself more comfortable and better attended to on board this small filthy old tub than I could possibly have expected. The Company avowedly employ in the Intercolonial lines the worst and most uncomfortable of their vessels, and the traveller who has to make any short passage, for instance, among the West India

islands, is exposed to the doubly disagreeable feeling of paying a very much higher rate of fare, for very inferior accommodation. The Medway was an old acquaintance of mine in my previous West Indian rambles, as in former years she performed the mail service between Belize, Jamaica, Hayti, Porto Rico, St. Thomas, and Havanna, and this opportunity of renewing my acquaintance with her I hailed with anything but a sentiment of satisfaction.

Early on the 25th June we ran into the extensive and beautiful bay of Carthagena, which now-a-days is only accessible on one side, the second entrance having been destroyed by the Spaniards during their supremacy, and never reopened. This seaport contains about 11,000 inhabitants, many churches and monasteries, as also large fortifications, but of trade and commerce there is next to nothing. In the roads there lay but three small coasting crafts. For the naturalist, and especially for the zoologist, Carthagena is on the other hand classic soil.
