Many advertisements appear in the papers of men who combined several vocations, dentistry being one of them, and in 1789 General Washington, after much pain during the summer, went into the hands of John Greenwood, dentist, of 56 William Street, New York, who made him a set of "sea-horse teeth". This had been a very trying summer, and one newspaper has it that "raw rum has been found exceeding pernicious in this extreme," and something lighter, like a "Bishop" or "Lawn sleeves" was recommended, and study of a book published in England called "Oxford Night-caps" was suggested as furnishing recipes for various healthful beverages though it was added that the rum had better be omitted, "as it is very intoxicating, and therefore pernicious." The President's guests could choose from among Madeira, claret, champagne, sherry, arrack, spirits, brandy, cordials, porter, beer, and cider, yet, with it all, unseemly intoxication seems to have been the exception. Domestic discipline in New York was enforced on servants, whether bound or free, by means of an official who was stationed at the calaboose on the common, and who, for a fee of one shilling, gave a thorough whipping. Education was fostered and colleges throve. By 1760 the records state that the "King's College (Columbia) buildings were so far completed that the officers and students began to lodge and mess therein." This was in accordance with the terms of the charter, which further provided that the students were to wear caps and gowns and to be within the gates at a certain hour. The plan of education, like our belongings, was copied from England, and our college was, in the most material parts, to be like Queen's College, Oxford. The tuition fee when General Washington entered his step-son, John Parke Custis, there, was five pounds per annum, with room-rent four pounds, and board at the rate of eleven shillings weekly. The late Andrew P. Peabody, writing of college life at Harvard in 1820, says: "Coal, just then coming into use, had hardly found its way into college. The student's rooms, several of the recitation-rooms as well were heated by open fires. Friction matches, which according to Faraday were the most useful invention in our age, were not yet." He says that the feather-bed was a valuable asset (this article had held its own for centuries), but that ten dollars would have covered the other contents of a student's room. It had no carpet, and a pine bedstead, a washstand, table and desk, and three or four chairs were all it contained, besides a cannon-ball to be heated on extra-cold nights, and rolled down stairs on warm ones, "at such time as might most nearly bisect a proctor's night's sleep."
