They went across the grass to the pear-tree, under which Isabel was still seated. It was growing dark, and her pale face and black eyes had a mysterious look in the dusky twilight. George Gilbert thought she was fitted to be the heroine of a romance, and felt himself miserably awkward and commonplace as he stood before her, struggling with the sensation that he had more arms and legs than he knew what to do with. I like to think of these three people gathered in this neglected suburban garden upon the 21st of July, 1852, for they were on the very threshold of life, and the future lay before them like a great stage in a theatre; but the curtain was down, and all beyond it was a dense mystery. These three foolish children had their own ideas about the great mystery. Isabel thought that she would meet a duke some day in the Walworth Road; the duke would be driving his cab, and she would be wearing her best bonnet and _not_ going to fetch butter; and the young patrician would be struck by her, and would drive off to her father, and there and then make a formal demand of her hand; and she would be married to him, and wear ruby velvet and a diamond coronet ever after, like Edith Dombey in Mr. Hablot Browne's grand picture. Poor George fashioned no such romantic destiny in his day-dreams. He thought that he would marry some pretty girl, and have plenty of patients, and perhaps some day be engaged in a great case which would be mentioned in the "Lancet," and live and die respected, as his grandfather had done before him, in the old house with the red-tiled roof and oaken gable-ends painted black. Sigismund had, of course, only one vision,--and that was the publication of that great book, which should be written about by the reviewers and praised by the public. He could afford to take life very quietly himself; for was he not, in a vicarious manner, going through more adventures than ever the mind of man imagined? He came home to Camberwell of an afternoon, and took half a pound of rump-steak and three or four cups of weak tea, and lounged about the weedy garden with the boys; and other young men who saw what his life was, sneered at him and called him "slow." Slow, indeed! Is it slow to be dangling from a housetop with a frayed rope slipping through your hands and seventy feet of empty space below you? Is it slow to be on board a ship on fire in the middle of the lonely Atlantic, and to rescue the entire crew on one fragile raft, with the handsomest female passenger lashed to your waist by means of her back hair? Is it slow to go down into subterranean passages, with a dark lantern and half-a-dozen bloodhounds, in pursuit of a murderer? This was the sort of thing that Sigismund was doing all day and every day--upon paper; and when the day's work was done, he was very well contented to loll in a garden-chair and smoke his cigar, while enthusiastic Isabel talked to him about Byron, and Shelley, and Napoleon
