The first stage of their honeymoon involved the long ride of over 250 miles to Pittsburgh, the hazards and discomforts of which we have learned from Rozier's description; it was marked in this instance by an accident, for in crossing the Alleghany mountains their coach was upset and Mrs. Audubon did not escape without severe bruises. At Pittsburgh the Audubons met a number of young emigrants bound westward like themselves, and in their company they prepared to float down the beautiful Ohio in a flatboat or ark. Their entire journey, which, owing to the windings of the river, could not have been much less than a thousand miles, was made in twelve days, and without further mishap. The wild and varied beauty of the Ohio of that day had great attractions for the naturalist, who often regretted that no facile writer had left a true and vivid picture of it for the benefit of posterity, for he foresaw with great concern the inevitable changes which advancing civilization would quickly produce along its delightful banks. Audubon traversed this mighty highway countless times in after life, and some of his musings have lost none of their interest with the flight of time, for he had witnessed the advance of the white man and the retreat of the red, along with the great herds of deer, elk and buffalo that once found peaceful pasturage on its banks. Speaking of a later but hardly less romantic journey,[170] he said: As night came, sinking into darkness the broader portions of the river, our minds became affected by strong emotions, and wandered far beyond the present moments. The tinkling of bells told us that the cattle which bore them were gently roving from valley to valley in search of food, or returning to their distant homes. The hooting of the Great Owl, or the muffled noise of its wings as it sailed smoothly over the stream, were matters of interest to us; so was the sound of the boatman's horn, as it came winding more and more softly from afar. When daylight returned, many songsters burst forth with echoing notes, more and more mellow to the listening ear. Here and there the lonely cabin of a squatter struck the eye, giving note of commencing civilization. The crossing of the stream by a deer foretold how soon the hills would be covered by snow. Many sluggish flatboats we overtook and passed; some laden with produce from the different head-waters of the small rivers that pour their tributary streams into the Ohio; others, of less dimensions, crowded with emigrants from distant parts, in search of a new home.
