It is not easy to determine the real motives for which the old Genoese city was abandoned in favour of its rival on the Cimmerian Bosphorus. The ostensible reasons were sanatory measures, the necessity of having a general quarantine at the entrance of the Sea of Azof, encouragement of coasters and lighters, and the utility of a vast emporium opened to the productions of all Russia. We believe, however, that all these arguments were in reality of very secondary weight, and that the downfall of Theodosia is to be ascribed to nothing else than an absurd vanity. To resuscitate the ancient name of Odessus; to found a town called Ovidiopol in a country where Ovid never resided; to lead our geographers into error by giving the name of Tiraspol to a mean village on the Dniestr, in the front of Bender; to substitute the name of Theodosia for that of Caffa; all these innovations might have pleased certain archaeologists, but how was it possible to resist the thought of rebuilding the celebrated capital of the kingdom of the Bosphorus? How irresistible the temptation to raise a new and great city at the foot of Mithridates' rock! The memory of the Milesians had, therefore, to fade before that of the illustrious sovereign of Pontus; Theodosia was despoiled of its privileges and its revenues, its tribunal of commerce was transferred to Kertch, and double arbour dues were imposed on vessels touching there before arriving at the latter port. Assuredly no stronger testimony could be borne to the superiority of Theodosia than that which was embodied in these arbitrary measures, nor could there be a more incontestible proof of the caprice to which the Genoese town was sacrificed. Caffa was infinitely better fitted than Kertch to satisfy those conditions which the official orders announced as the grounds for destroying its commercial position. The Kertch roads are often closed against vessels for three or four months continuously; the anchorage is unsafe, and often disastrous, both from the want of shelter and from the shallowness of the water. The port of Theodosia, on the contrary, is always open, and shipwrecks are unknown there. During the fine season an active service of lighters might have concentrated there all the freights brought by the Don and the Sea of Azof. In this way the commercial intercourse with Russia by the Black Sea would never have suffered the least interruption; and, what is an incalculable advantage in those latitudes, foreign vessels, being no longer constrained to make the long and difficult passage to Taganrok, or to run the risk of wintering in the ice, might, if they failed to obtain freight at Theodosia, have proceeded in search of one without loss of time to the southern shores of the Black Sea. All these grand considerations, which had raised the prosperity of Caffa so high, were superseded by the dictates of vanity.
Kertch then was declared, in 1827, a port of the first class, with a custom-house of entry and exit. A vast lazaret was immediately constructed, and five years afterwards appeared the famous sanatory orders which still regulate the navigation of the Sea of Azof. The duration of the quarantine was fixed at thirty days, but before that time can begin to run, the vessel must be moored within the lazaret, and every thing on board, including the effects of the crew, must be subjected to a fumigation of twenty-four hours. This operation being ended the sailors land, after having first divested themselves of all their dress and portable articles; the sails are plunged in water by the servants of the establishment, and the hull of the vessel is disinfected. After these preliminaries, which often occupy from ten to fifteen days, the sailors return to their vessels, and their days of quarantine begin to count. All these regulations are in curious contrast with those of the lazaret of Odessa, where the quarantine lasts only fifteen days.
