But the great thing is what he did for the law. The current distribution of the common law under its larger heads was made by Hale and Blackstone after that of the contemporary civilians, which is founded upon that of the Institutes of Justinian. This book is but a reproduction of that of Gaius. So we may assert of this last mentioned author that it is his systematization which still obtains both in the English and Roman law, that is to say, the entire law of the enlightened world.[78] A few English chancellors perceptibly moulded equity; Mansfield almost created English commercial law; in our country, Hamilton, in one argument overturned the doctrine of tacking securities, and in another remade the essentials of libel; our great text-author Bishop, with his treatise often worked over in new editions, is really the enacter of the American law of divorce; and Marshall's additions to our federal law will never be forgotten. By what he did in Gibbons _v._ Ogden, Webster has won a proud place in the small company of great law-givers. And he is entitled to a liberal share of the glory which the Dartmouth college decision has won, for without him Marshall would have had no opportunity. To estimate the prodigious effect of the rulings in these two cases, try to realize to yourself what would be the consequences to American trade and commerce if the States were not effectually kept from infringing contracts or granting monopolies of transportation. Try to realize the loss, the inconvenience, the trouble, the vexation, all the evil that would have unavoidably befallen us if these two companion decisions and the subsequent ones following them as precedents or extending them as analogies, had not made practically the whole of American inland business a unit--to use Webster's word--under the protection everywhere of the same impartial law. The longer you think it over the more confirmed will be your opinion that from no other cause has the evolution away from the old independence of States towards a permanent union and a single organism of perpetually federated communities been more furthered. The unification of production and distribution thus given resistless impulse has almost of itself alone worked the unification of all our States. So looking back from the standpoint of to-day we may be sure that the powers had Webster by his accomplishment in the cases now in mind, to build for perpetual union far better than he knew. It needs not to dwell upon the Bunker Hill oration, made June 17, 1825. It is, as I believe, the most familiar as a whole of all speeches to Americans. It did not stop with adding greatly to the influence he had won over New England by the Plymouth oration; it revealed him to the whole country as its supreme orator. Bear in mind its theme, remembering how large a part the battle of Bunker Hill was in founding our union.
