"The mules themselves are, as I have already stated, so worn-out, and broken-down, that it requires the utmost vigilance and care on the part of their riders to prevent them dropping, and precipitating them into the mire. In order to guard as much as possible against this contingency, whenever ladies travel this route, they are obliged to discard the side-saddle, and resort to a less feminine style of equitation. I overtook a party of about twenty persons on the road, amongst whom was a married lady on her way to the States; and I watched her rather curiously, to observe how she got over the difficulties that beset her. Being fortified with that article of male attire, the figurative possession of which is said to denote domestic ascendency, she thought it incumbent upon her, I suppose, to display all the courage and nerve that should properly be encased in it. Several times, when I fancied that both she and her mule were on the point of being capsized, she recovered herself with admirable presence of mind, and seemed to enjoy the risk exceedingly. "As to myself, I floundered on as well as I could with a mule tottering beneath me from sheer exhaustion, and sinking every minute up to his knees in mud. It seemed to me that we were making little or no progress; and I became thoroughly tired and disheartened. I do not know any temptation, however powerful, that would again induce me to encounter the never-ending series of difficulties and annoyances that laid in wait for me at every step; and I must candidly own, that even the force of female example, of which I had so merry a specimen before me, did not at all shame me into a less impatient endurance of them. "The negroes whom I met on their way to and from Panama excited my astonishment, from the amount of physical exertion which they seemed capable of undergoing. With their legs and feet bare, and nothing but a cloth around their loins, they carried enormous burdens on their backs, stepping from stone to stone with wonderful strength and dexterity. These poor creatures must lead the most wretched and laborious of all the painful modes of existence to which their race is condemned; and not even long habit, or their peculiar physical construction, can divest it of its distressing character in the eyes of a stranger. They all bear, on their hard and wrinkled faces, the stamp of overtaxed strength; but they seemed content with their lot, and will, doubtless, regret the formation of a better route, as tending to depreciate the value of their services. Notwithstanding the toilsome and laborious nature of their occupations, however, the carriers of Panama are the hardiest and most muscular race to be seen here; for the rest of the population, both white and black, are of comparatively sickly and diminutive appearance.
