This brief sketch of the true province of legislation is enough to evince its vast importance. How great is the influence of the lawyers as a class upon legislation! Let any man look upon all that has been done in this department, and trace it to its sources. He will acknowledge that legislation, good or bad, springs from the Bar. There is in this country no class of lawyers confined to the mere business of the profession--no mere attorneys--no mere special pleaders--no mere solicitors in Chancery--no mere conveyancers. However more accurate and profound may be the learning of men, whose studies are thus limited to one particular branch, it is not to be regretted either on account of its influence on the science or the profession. The American lawyer, considering the compass of his varied duties, and the probable call which will be made on him especially to enter the halls of legislation, must be a Jurist. From the ranks of the Bar, more frequently than from any other profession, are men called to fill the highest public stations in the service of the country, at home and abroad. The American lawyer must thus extend his researches into all parts of the science, which has for its object human government and law: he must study it in its grand outlines as well as in the filling up of details. He is as frequently called upon to inquire what the law ought to be as what it is. While a broad and marked line separates, and always ought to separate the departments of Legislation and Jurisprudence, it is a benefit to both that the same class of men should be engaged in both. Practice will thus be liberalized by theory, and theory restrained and corrected by practice. The mere abstractionist or _doctrinaire_ would aim at the formation of a code of great simplicity: the practitioner sees in it the parent of uncertainty and injustice. Legal propositions cannot be framed with the certainty of mathematical theories. The most carefully studied language still leaves room for interpretation and construction. Time itself, which works such mighty changes in all things, produces a state of circumstances not in the mind of the lawgiver. The existing system, it may be, is an unwieldy, inconvenient structure, heavy and grotesque from the mixed character of its architecture outwardly, inwardly its space too much occupied and its inmates embarrassed by passages and circuities. The abstractionist would at once demolish it, and replace it by a light, commodious and airy dwelling, more symmetrical and chaste in its appearance, better fitted for the comfort and usefulness of its inhabitants. The practitioner, who has become familiar with it, who observes and admires that silent legislation of the people, which shows itself not on the pages of the statute book, and receives its recognition in courts of justice only after it has ceased to need even that to give it form and vitality, and who understands, therefore, how,
