Time is the surest emancipator after all; for proof of which look not to the prospect presented here, but turn back on the old States. At what period did philanthropy triumph there? why exactly at that point where interest joined issue with its dictates; the slave was, in fact, admitted as a hired labourer, when he ceased to be profitable as a bondsman: and that day will arrive here also, as surely as that the sun shines on Louisiana; and the lower valley of the Mississippi will yet be peopled by a free and hardy race, born on the soil made each year more fruitful and less pestilential, until it shall rival the valleys of the Ganges or the Nile, if not in the splendour of art, at least in the more solid and enduring possessions,--education, intelligence, and freedom; for only whilst so sustained can the institutions of democracy exist; these once failing to advance hand-in-hand with population, the whole fabric will, with inconceivable rapidity, be resolved into a rude anarchy for some bold mind to re-form and re-model. One of the greatest works now in progress here, is the canal planned to connect Lac Pontchartrain with the city. In the month of February it was completed to within three miles of the lake; and as it was a pleasant ride to the point where the digging was in progress, I two or three times visited the scene, after its bearings had been explained by the two intelligent persons under whose guidance I first penetrated the swamp. I only wish that the wise men at home who coolly charge the present condition of Ireland upon the inherent laziness of her population, could be transported to this spot, to look upon the hundreds of fine fellows labouring here beneath a sun that at this winter season was at times insufferably fierce, and amidst a pestilential swamp whose exhalations were foetid to a degree scarcely endurable even for a few moments; wading amongst stumps of trees, mid-deep in black mud, clearing the spaces pumped out by powerful steam-engines; wheeling, digging, hewing, or bearing burdens it made one's shoulders ache to look upon; exposed meantime to every change of temperature, in log-huts, laid down in the very swamp, on a foundation of newly-felled trees, having the water lying stagnant between the floor-logs, whose interstices, together with those of the side-walls, are open, pervious alike to sun or wind, or snow. Here they subsist on the coarsest fare, holding life on a tenure as uncertain as does the leader of a forlorn hope; excluded from all the advantages of civilization; often at the mercy of a hard contractor, who wrings his profits from their blood; and all this for a pittance that merely enables them to exist, with little power to save, or a hope beyond the continuance of the like exertion.
