"In most lines the highest gift is the gift of toil. Indeed, men of genius have often been the most terrible of toilers, and in the regions of highest art. How have the great masters of music first welded the keys of the organ and harpsichord to their fingers' ends and their souls' nerves before they poured forth the Creation or the Messiah, the symphonies and sonatas! Think of Meyerbeer and his fifteen hours of daily work; of Mozart's incessant study of the masters, and his own eight hundred compositions in his short life; of Mendelssohn's nine years elaboration of Elijah. Or in the sister art, how we track laborious, continuous study in the Peruginesque, the Florentine, and the Roman styles successively of Raphael, and in the incredible activity that crowded a life of thirty-seven years with such a vast number of portraits and Madonnas, of altar-pieces and frescoes, mythological, historical, and Biblical. And that still grander contemporary genius, how he wrought by night with the candle in his pasteboard cap, how he had dissected and studied the human frame like an anatomist or surgeon before he chiseled the David and Moses, or painted the Sistine chapel, and how the plannings of his busy brain were always in advance of the powers of a hand that, till the age of eighty-eight, was incessantly at work. "The servant is not above his master. The lower intellect can buy at no cheaper price than the higher, and the hour of full intellectual emancipation comes only when the student has learned to serve--to turn the whole freshness and sharpness of his intellect on any needful theme of the hour; it may be the scale of a fossil fish, or the annual movement of a glacier, the disclosures of the spectrum, or the secrets of the arrow-headed tongue. All great explorers have been largely their own teachers, and each young scholar has made the best use of all helps and helpers when he has learned to teach himself. His emancipation, once fairly purchased, confers on him potentially the freedom of the empire of thought; and, as evermore, the freeman toils harder than the slave. The strong stimulus of such a self-moved activity, thoroughly aroused, becomes in Choate or Gladstone the fountain of perpetual youth, and forms the solid basis of the titanic scholarship of Germany. It stood embodied in the life and motto of the aged, matchless artist Angelo,--'_Ancora imparo_,' I am learning still.
