It is a circumstance of curious interest that nearly, if not quite, all the arguments used by the supporters and opponents of a protective system were presented at that time and with a directness and ability which have not been surpassed in any subsequent discussion. The "_ad valorem_" system of levying duties was maintained against "specific" rates in almost the same language employed in the discussions of recent years. The "infant manufactures," the need of the "fostering care of the government" for the protection of "home industry," the advantages derived from "diversified pursuits," the competition of "cheap labor in Europe," were all rehearsed with a familiarity and ease which implied their previous and constant use in the legislative halls of the different States before the power to levy imposts was remitted to the jurisdiction of Congress. A picture of the industrial condition of the country at that day can be inferred from the tariff bill first passed; and the manufactures that were deemed worthy of encouragement are clearly outlined in the debate. Mr. Clymer of Pennsylvania asked for a protective duty on steel, stating that a furnace in Philadelphia "had produced three hundred tons in two years, and with a little encouragement would supply enough for the consumption of the whole Union." The Pennsylvania members at the same time strenuously opposed a duty on coal which they wished to import as cheaply as possible to aid in the development of their iron ores. The manufacture of glass had been started in Maryland, and the members from that State secured a duty on the foreign article after considerable discussion, and with the significant reservation, in deference to popular habits, that "black quart-bottles" should be admitted free.
