Such commodities however as are _deemed_ incapable of retaining or communicating the infectious taint, as corn, &c. are permitted to be landed immediately by the mariners themselves, at proper places provided for that purpose, which are generally called LAZARETTOS, some of which in the principal ports of the Mediterranean are of very considerable extent, and as to division and appropriation appear so well calculated for their intended purposes as to be worthy of imitation. The best praise of their regulation is indeed to be found in their success; for though twelve months never elapse but that the plague rages in some part of the Levant and of the coasts of Barbary, the infection has seldom reached the coasts of Italy, France, or Spain. Terrible exceptions may be adduced to this remark, yet they may generally be traced to some clandestine violation of the Quarantine laws, rather than to their imperfect execution, as in the recent instance of the plague[211] at Malta in 1813, when the cupidity of a poor cobler in smuggling some materials from a Greek or Turkish vessel in the harbour of Valetta, introduced the pest into the island, to which he and his family fell the first victims. The objections to the Quarantine laws, as executed in the Mediterranean, arise more from the indiscriminate and vexatious application of them to cases for which they were not provided, than from any general relaxation or want of vigilance in the officers appointed to enforce them: occasionally indeed the courtesy of these gentlemen will deem a governor or wealthy noble to be incapable of communicating infection, though from the most suspected port, while a whole fleet of merchantmen, arriving with clean bills from the Atlantic, will be detained for some weeks, _ex abundanti cautela_, without admission to _pratique_; from such instances travellers who have been annoyed, and merchants who have been injured, have imbibed a very general prejudice against these laws; nor have they wanted learned authorities to contend with them for their abolition, on the grounds of their abstract inutility in preventing infection (admitting the contagious nature of the disease which some have denied), and the injurious tendency to the general interests of commerce.
