As Monsieur and Madame de Hell resided for a year in Constantinople, it is needless to say they remained long enough for the glamour to disappear, in which at first their lively imaginations had invested everything around them. The gorgeous visions vanished, and their eyes were opened to the hard realities of Mohammedan ignorance, bigotry and misgovernment. They learned, perhaps, that the order and freedom of Western civilization are infinitely more valuable than the picturesqueness of Oriental society. In 1838 they set out for Odessa, where Monsieur de Hell hoped to obtain a position worthy of his talents. The future of the young couple rested wholly on a letter of recommendation to General Potier, by whom they were warmly welcomed. The general, who owned a large estate in the neighbourhood, where he cultivated a famous breed of Merino sheep, had formed a project for erecting mills upon the Dnieper. To carry it out he needed an engineer, and in M. Hommaire de Hell he found one. Straightway they proceeded to his estate at Kherson, and M. de Hell set to work on the necessary plans. While thus engaged, he conceived the idea of a scientific expedition to the Caspian Sea--a basin of which little was then known to our geographers--and this idea held him so firmly that, a few months later, he gave up his employment in order to realize it. In one of his excursions to the cataracts of the Dnieper, where the mills were to be erected, his geological knowledge led him to the discovery of the rich veins of an iron mine, which has since been profitably worked. "This period of my life," wrote Madame de Hell, afterwards, "spent in the midst of the steppes, remote from any town, appears to me now in so calm, tender, and serene a light, that the slightest memorial of it moves me profoundly. Only to see the shore where we passed whole days in seeking for shells, only to hear the sound of the great waves rolling on the sandbanks and among the seaweed, only to recall a single one of the impressions of that happy epoch, I would willingly repeat the voyage." * * * * * For his great scientific expedition, M. de Hell made vigorous preparations during the winter of 1838, and having obtained from Count Vorontzov, the governor of New Russia, strong letters of recommendation to the governors and officials of the provinces he would have to traverse, he and his wife started in the middle of May, 1839, accompanied by a Cossack, and an excellent dragoman, who spoke all the dialects current in Southern Russia. Their journey through the country of the Don Cossacks we shall pass over, as offering nothing of special novelty or interest, and take up Madame de Hell's narrative at the point of her arrival on the banks of the Volga.
