deal of uncongenial activity, I found the quiet of my temporary haven more attractive than anything that the great town could offer.  I already knew London well; that is to say, I had long ago satisfied (so far as it was capable of satisfaction) that mysterious yearning—­the magnetism of millions of hearts operating upon one—­which impels every man’s individuality to mingle itself with the immensest mass of human life within his scope.  Day after day, at an earlier period, I had trodden the thronged thoroughfares, the broad, lonely squares, the lanes, alleys, and strange labyrinthine courts, the parks, the gardens and inclosures of ancient studious societies, so retired and silent amid the city-uproar, the markets, the foggy streets along the river-side, the bridges,—­I had sought all parts of the metropolis, in short, with an unweariable and indiscriminating curiosity; until few of the native inhabitants, I fancy, had turned so many of its corners as myself.  These aimless wanderings (in which my prime purpose and achievement were to lose my way, and so to find it the more surely) had brought me, at one time or another, to the sight and actual presence of almost all the objects and renowned localities that I had read about, and which had made London the dream-city of my youth.  I had found it better than my dream; for there is nothing else in life comparable (in that species of enjoyment, I mean) to the thick, heavy, oppressive, sombre delight which an American is sensible of, hardly knowing whether to call it a pleasure or a pain, in the atmosphere of London.  The result was, that I acquired a home-feeling there, as nowhere else in the world,—­though afterwards I came to have a somewhat similar sentiment in regard to Rome; and as long as either of those two great cities shall exist, the cities of the Past and of the Present, a man’s native soil may crumble beneath his feet without leaving him altogether homeless upon earth.

Thus, having once fully yielded to its influence, I was in a manner free of the city, and could approach or keep away from it as I pleased.  Hence it happened, that, living within a quarter of an hour’s rush of the London Bridge Terminus, I was oftener tempted to spend a whole summer-day in our garden than to seek anything new or old, wonderful or commonplace, beyond its precincts.  It was a delightful garden, of no great extent, but comprising a good many facilities for repose and enjoyment, such as arbors and garden-seats, shrubbery, flower-beds, rose-bushes in a profusion of bloom, pinks, poppies, geraniums, sweet-peas, and a variety of other scarlet, yellow, blue, and purple blossoms, which I did not trouble myself to recognize individually, yet had always a vague sense of their beauty about me.  The dim sky of England has a most happy effect on the coloring of flowers, blending richness with delicacy in the same texture; but in this garden, as everywhere else, the exuberance of English verdure had a greater charm than any tropical
