Then as soon as his father began to beat the lad, and his mother was not able to protect him, Cleg developed a marvellous litheness and speed. He could climb roofs like a cat at five years of age, and watch his father from the ledge of an outlying wall or the side of a reeking chimney-can, where even the foot of the practised burglar dared not venture. Then came a year black and bitter. It was the year of the small-pox. That part of Edinburgh where the Kellys lived became a walled city. There was one death in every three or four attacked. And Tim Kelly went to the seaside for his health. But Isbel and her boy battled it out alone. She had seven shillings a week for cleaning a day-school. But soon the schools were closed, and her pay ceased. Nevertheless, she earned money somehow, and the minister of the McGill-Gillespie church visited her. It would take a whole treatise on Church History, and a professor thereof, to tell why that church was called the McGill-Gillespie. But the unlearned may be assured that these excellent gentlemen were not canonised Scottish saints, nor were their effigies worshipped inside. But at this time the minister of the church came very near to being worshipped outside. The children knew his step, and ran—_to_, not _from_, him. He was the only man, except the doctor, at whom the urchins of Meggat's did not fling dirt. One of these had even been known to touch his hat to the minister of McGill-Gillespie. But this was a great risk, and of course he did not do it when any one was looking. One day Cleg Kelly sickened, and though at the time he was a great boy of six, his mother carried him about in her arms all day, soothing him. And the hot, dry spots burned ever brighter on his cheeks, and his eyes shone like flame. The minister brought the doctor, for they hunted in couples—these two. Some of the ministers had gone to the seaside with Timothy Kelly, and along with them a few great professional men from the West-End. But the Pleasance doctor, a little fair man, and the minister of McGill-Gillespie, a tall dark man, remained with the small-pox. Also God was there—not very evidently, or obtrusively, perhaps; but the minister of McGill-Gillespie knew where to find Him when He was wanted. And He was needed badly enough in the sick-room of Cleg Kelly. No doubt Cleg ought to have gone to the hospital. But, for one thing, the hospitals were overcrowded. And, for another, if they had taken Cleg, they might have taken his mother also. At all events Cleg was nursed in his home, while his father remained at the seaside for his health.
