After his return to Spain he was again laid by. He was disappointed, but not discouraged, for the self-pity of the invalid never deprived him of his strong man's humor. "When I drive out and notice the opening of spring, I feel sometimes almost moved to tears at the thought that in a little while I shall again have the use of my limbs, and be able to ramble about and enjoy these green fields and meadows. It seems almost too great a privilege. I am afraid when I once more sally forth and walk the streets, I shall feel like a boy with a new coat, who thinks everybody will turn around to look at him. 'Bless my soul, how that gentleman has the use of his legs!'" A few days after this was written, he got word that one of his friends had just undergone a successful surgical operation. "God bless these surgeons and dentists!" he exclaims. "May their good deeds be returned upon them a thousand fold! May they have the felicity, in the next world, to have successful operations performed upon them to all eternity!" By this time he had come to take Spanish politics rather too seriously. The insincerity and profligacy of the Spanish character, the corruption of the court and state, fairly sicken him: "The last ten or twelve years of my life," he writes, "have shown me so much of the dark side of human nature, that I begin to have painful doubts of my fellow men, and look back with regret to the confiding period of my literary career, when, poor as a rat, but rich in dreams, I beheld the world through the medium of my imagination, and was apt to believe men as good as I wished them to be." His sense of responsibility for the young queen oppressed him, and he looked forward impatiently to the hour of his release. A year later he had gained far better health and spirits. On his sixty-second birthday--"I caught myself bounding upstairs three steps at a time, to the astonishment of the porter, and checked myself, recollecting that it was not the pace befitting a minister and a man of my years." His mental life had, however, caught the sober tone of age. "I am now at that time of life when the mind has a stock of recollections on which to employ itself; and though these may sometimes be of a melancholy nature, yet it is a 'sweet-souled melancholy,' mellowed and softened by the operation of time, and has no bitterness in it.... When I was young, my imagination was always in the advance, picturing out the future, and building castles in the air; now memory comes in the place of imagination, and I look back over the region I have traveled. Thank God, the same plastic feeling, which used to deck all the future with the hues of fairyland, throws a soft coloring over the past, until the very roughest places, through which I struggled with many a heartache, lose all their asperity in the distance."
