For a fourth benefit, age sets its house in order, and finishes its works, which to every artist is a supreme pleasure. Youth has an excess of sensibility, before which every object glitters and attracts. We leave one pursuit for another, and the young man’s year is a heap of beginnings. At the end of a twelvemonth, he has nothing to show for it,--not one completed work. But the time is not lost. Our instincts drove us to hive innumerable experiences, that are yet of no visible value, and which we may keep for twice seven years before they shall be wanted. The best things are of secular growth. The instinct of classifying marks the wise and healthy mind. Linnæus projects his system, and lays out his twenty-four classes of plants, before yet he has found in Nature a single plant to justify certain of his classes. His seventh class has not one. In process of time, he finds with delight the little white _Trientalis_, the only plant with seven petals and sometimes seven stamens, which constitutes a seventh class in conformity with his system. The conchologist builds his cabinet whilst as yet he has few shells. He labels shelves for classes, cells for species: all but a few are empty. But every year fills some blanks, and with accelerating speed as he becomes knowing and known. An old scholar finds keen delight in verifying the impressive anecdotes and citations he has met with in miscellaneous reading and hearing, in all the years of youth. We carry in memory important anecdotes, and have lost all clew to the author from whom we had them. We have a heroic speech from Rome or Greece, but cannot fix it on the man who said it. We have an admirable line worthy of Horace, ever and anon resounding in our mind’s ear, but have searched all probable and improbable books for it in vain. We consult the reading men: but, strangely enough, they who know everything know not this. But especially we have a certain insulated thought, which haunts us, but remains insulated and barren. Well, there is nothing for all this but patience and time. Time, yes, that is the finder, the unweariable explorer, not subject to casualties, omniscient at last. The day comes when the hidden author of our story is found; when the brave speech returns straight to the hero who said it; when the admirable verse finds the poet to whom it belongs; and best of all, when the lonely thought, which seemed so wise, yet half-wise, half-thought, because it cast no light abroad, is suddenly matched in our mind by its twin, by its sequence, or next related analogy, which gives it instantly radiating power, and justifies the superstitious instinct with which we have hoarded it. We remember our old Greek Professor at Cambridge, an ancient bachelor, amid his folios, possessed by this hope of completing a task, with nothing to break his leisure after the three hours of his daily classes, yet ever restlessly stroking his leg, and assuring himself “he should retire from the
