We may also concede that, in the realm of intellectual endeavor, the natural and physical sciences should have the precedence of history. The present is more important than the past, and those sciences which contribute to our comfort, place within the reach of the laborer and mechanic as common necessaries what would have been the highest luxury to the Roman emperor or to the king of the Middle Ages, contribute to health and the preservation of life, and by the development of railroads make possible such a gathering as this,--these sciences, we cheerfully admit, outrank our modest enterprise, which, in the words of Herodotus, is "to preserve from decay the remembrance of what men have done." It may be true, as a geologist once said, in extolling his study at the expense of the humanities, "Rocks do not lie, although men do;" yet, on the other hand, the historic sense, which during our century has diffused itself widely, has invaded the domain of physical science. If you are unfortunate enough to be ill, and consult a doctor, he expatiates on the history of your disease. It was once my duty to attend the Commencement exercises of a technical school, when one of the graduates had a thesis on bridges. As he began by telling how they were built in Julius Caesar's time, and tracing at some length the development of the art during the period of the material prosperity of the Roman Empire, he had little time and space left to consider their construction at the present day. One of the most brilliant surgeons I ever knew, the originator of a number of important surgical methods, who, being physician as well, was remarkable in his expedients for saving life when called to counsel in grave and apparently hopeless cases, desired to write a book embodying his discoveries and devices, but said that the feeling was strong within him that he must begin his work with an account of medicine in Egypt, and trace its development down to our own time. As he was a busy man in his profession, he lacked the leisure to make the preliminary historical study, and his book was never written. Men of affairs, who, taking "the present time by the top," are looked upon as devoted to the physical and mechanical sciences, continually pay tribute to our art. President Garfield, on his deathbed, asked one of his most trusted Cabinet advisers, in words that become pathetic as one thinks of the opportunities destroyed by the assassin's bullet, "Shall I live in history?" A clever politician, who knew more of ward meetings, caucuses, and the machinery of conventions than he did of history books, and who was earnest for the renomination of President Arthur in 1884, said to me, in the way of clinching his argument, "That administration will live in history." So it was, according to Amyot, in the olden time. "Whensoever," he wrote, "the right sage and virtuous Emperor of Rome, Alexander Severus, was to consult of any matter of
