But for all that he ought to have had that packet of apples better tied up, for he had bought a whole shilling'sworth on his way down. The chief was rather partial to a good apple himself; and, in any case, it is always advisable to be on the safe side of one's wife, even if you are a chief of police. Now the chief reckoned without the Knuckle Dusters. These valiant youths were on the war-path, and as he was passing a point where the houses are few, along by the dock gates, Tam Luke came alongside and pulled the string of his parcel with a sharp and knowing twitch. Instantly it came undone, and the apples rolled every way upon the street. Thereupon every Knuckle Duster seized as many as he could reach, and the Club scattered like hunted hares down alleys and over fences. For a moment the chief stood thunderstruck. Then he gave chase, selecting Cleaver's boy for his prey. But he found that he was not quite so supple as when he was a young constable fresh from the country. And besides, he heard the warning whistle blow from the "Lord Aberdour." He pictured his bairns on the quay and his wife looking out for him. After all, was it worth it? So he darted into a shop and bought chocolate instead, and took his anger out by saying, "I'll wager I'll make it warm for these young vagabonds." He said it as many as forty times on the way over. He never minded the scenery one single bit. Among the Knuckle Dusters there was great jubilation. That night they told the whole to Celie Tennant, who was horrified; but she could only advise them to "restore fourfold," an unknown idea to the Club. It was, however, a proposition ably advocated by Cleg Kelly, who, owing to absence, not honesty, had taken no part in the larceny. And, strictly as a humorous conception, the idea of fourfold restitution caught on wonderfully. This is why a very dirty paper containing two shillings came to the chief of the Leith police, with the inscription thereon: "FOR TO BUY MAIR AIPPLES." Celie wanted them to send four shillings, but the Club unanimously declined, because the grocer's boy said that the chief's apples were only second quality. And the Club had every confidence in the grocer's boy being well-informed on the point. [Illustration: "Our roads separate here."] ADVENTURE XIX. THE PILGRIMS OF THE PENNY GAFF. The junior partner was, as he expressed it, "down on his luck." He was heartily sorry for himself, and indeed the fault was not all his own. It was now some considerable time since he began regularly to see home the lady member of the Knuckle Dusters' Club, and perhaps he had begun to some extent to presume upon his standing. He had, in fact, taken it upon him to warn her as to the difficulties of her position. "It is not right for a young lady to be about in this district at night—no girl ought to do it, whatever be her motive." He was sometimes a very short-sighted junior partner. Celie Tennant fired up.
