furnished with every thing to make a night passage pleasant. It is upwards of one hundred miles from Baltimore to Philadelphia, by land, even by their lately improved roads; yet, with no interruption except being transported some sixteen or twenty miles over good roads, in very bad stage coaches, we enjoyed ourselves in our births till I was awakened before nine the next morning, by the steward, who informed me we were at the wharf, in the place of our destination. I forthwith repaired, as my previous instructions directed, to the large and commodious hotel of Mr. R.; where I met with several of my old friends, and some quondam fellow-voyagers, who, influenced by business, or perhaps the same instinctive dread of yellow fever with myself, had found their way to this city.--Here, my dear W., I still remain. In the twenty-four hours that have scarcely elapsed since my arrival, I have seen nothing distinctly; for after the monotony of a sea voyage, and the dizziness consequent on an exchange from the ocean to _terra firma_, some few days must be allotted to repose. _Treatise on Agriculture_. SECT. I. On the Rise and Progress of Agriculture. The origin of this art is lost among the fables of antiquity, and we have to regret, that in the present state of knowledge, we are even ignorant of the _time_, when the plough was invented, and of the _name_ and _condition_ of the inventor. When therefore we speak of the beginning of the art, we but allude to certain appearances which indicate its existence, and the employment given by it to the minds, as well as to the hands, of mankind. Such were the artificial canals and lakes of Egypt. Menaced at one time by a redundancy of water, and at another by its scarcity or want, the genius of that extraordinary people could not but employ itself, promptly and strenuously, in remedying these evils, and eventually, in converting them into benefits; and hence it was, that when other parts of the world exhibited little more of agricultural knowledge than appertains to the state of nature, imagined by philosophers, the Egyptians thoroughly understood and skilfully practised _irrigation_, that most scientific and profitable branch of the art.[1] Like their own Nile, their population had its overflow, which colonized Carthage and Greece, and carried with it the talent and intelligence of the mother country. The former of these states, though essentially commercial, had its _plantations_, and so highly prized were the agricultural works of Mago, that when Carthage was captured, they alone, of the many books found in it, were retained and translated by the Romans. A similar inference may be drawn from the history of Greece; for assuredly that art could not have been either unknown or neglected, which so long employed the pen and the tongue of the great Xenophon.[2] It must however be admitted, that of the ancient nations, it is only among the Romans, that we
