The memory has a fine art of sifting out the pain and keeping all the joy. The spring days when the bluebird arrives have usually only few hours of fine temperature, are sour and unlovely; but when late in autumn we hear rarely a bluebird’s notes they are sweet by reminding us of the spring. Well, it is so with other tricks of memory. Of the most romantic fact the memory is more romantic; and this power of sinking the pain of any experience and of recalling the saddest with tranquillity, and even with a wise pleasure, is familiar. The memory is as the affection. Sampson Reed says, “The true way to store the memory is to develop the affections.” A _souvenir_ is a token of love. _Remember me_ means, Do not cease to love me. We remember those things which we love and those things which we hate. The memory of all men is robust on the subject of a debt due to them, or of an insult inflicted on them. “They can remember,” as Johnson said, “who kicked them last.” Every artist is alive on the subject of his art. The Persians say, “A real singer will never forget the song he has once learned.” Michael Angelo, after having once seen a work of any other artist, would remember it so perfectly that if it pleased him to make use of any portion thereof, he could do so, but in such a manner that none could perceive it. We remember what we understand, and we understand best what we like; for this doubles our power of attention, and makes it our own. Captain John Brown, of Ossawatomie, said he had in Ohio three thousand sheep on his farm, and could tell a strange sheep in his flock as soon as he saw its face. One of my neighbors, a grazier, told me that he should know again every cow, ox, or steer that he ever saw. Abel Lawton knew every horse that went up and down through Concord to the towns in the county. And in higher examples each man’s memory is in the line of his action. Nature trains us on to see illusions and prodigies with no more wonder than our toast and omelet at breakfast. Talk of memory and cite me these fine examples of Grotius and Daguesseau, and I think how awful is that power and what privilege and tyranny it must confer. Then I come to a bright school-girl who remembers all she hears, carries thousands of nursery rhymes and all the poetry in all the readers, hymn-books, and pictorial ballads in her mind; and ’tis a mere drug. She carries it so carelessly, it seems like the profusion of hair on the shock heads of all the village boys and village dogs; it grows like grass. ’Tis a bushel-basket memory of all unchosen knowledge, heaped together in a huge hamper, without method, yet securely held, and ready to come at call; so that an old scholar, who knows what to do with a memory, is full of wonder and pity that this magical force should be squandered on such frippery.
