146 THE CRATER; As for the soil, on examination Mark found it had been greatly improved by the manure, tillage and water it had received. The hogs were again let in to turn it over with their snouts, and this they did most effectually in the course of two or three days. By this time, in addition to the three grown porkers our young man possessed, there were no less than nine young ones. This number was getting to be formidable, and he saw the necessity of killing off, in order to keep them within reasonable limits. One of the fattest and best he converted into pickled pork, not from any want of that article, there being still enough left in the ship to last him several years, but because he pre ferred it corned to that which had been in the salt so long a time. He saw the mistake he had made in allowing the pigs to get to be so large, since the meat would spoil long before he could consume even the smallest-sized shouts. For their own good, however, he was compelled to shoot no less than five, and these he buried entire, in deep places in his garden, having heard that earth which had imbibed animal substances, in this way, was converted into excel lent manure. Mark now made a voyage to Loam Island, in quest of a cargo, using the raft, and towing the dingui. It was on this occasion that our young man was made to feel how much he had lost, in the way of labour, in being deprived of the assistance of Bob. He succeeded in loading his raft, however, and was just about to sail for home again, when it occurred to him that possibly the seeds and roots of the asparagus he had put into a corner of the deposit might have come to something. Sure enough, on going to the spot, Mark found that the seed had taken well, and hundreds of young plants were growing flourishingly, while plants fit to eat had pushed their tops through the loam, from the roots. This was an important discovery, aspara gus being a vegetable of which Mark was exceedingly fond, and one easily cultivated. In that climate, and in a soil sufficiently rich, it might be made to send up new shoots the entire year; and there was little fear of scurvy so long as he could obtain plenty of this plant to eat. The melons and other vegetables, however, had removed all Mark s dread of that formidable disease; more especially as he
