CHIPPY GOES IN CHASE

Chippy's heart beat high with excitement. It thumped against his ribs till he felt sure that the talkers a few yards away would hear it; and he turned and crept away, and circled round to the back of the fish-shed, where he pulled up to think over what he had heard. He felt sure that he had hit upon the thieves. What should he do? Run to Martin and tell him what he had found out? Chippy considered that, then shook his head. He knew Martin, and Martin knew Chippy. 'He'd ne'er believe me,' thought Chippy. 'He'd think I was a-tryin' to kid 'im.'

Martin was a good, zealous officer, but rather a dull one, and Chippy knew that he would be very slow to give any credit to a story brought him by a wharf-rat. And then, they were not the best of friends. Chippy now entertained the most respectful regard for police-constables, for it was part of his duty; but it had not always been so. In his days of sin, before he became a boy scout, he had guyed and chaffed Martin many a time and oft, and had exercised a diabolical ingenuity in tricks for his discomfiture. Therefore a sudden appearance, springing out of the darkness as a supporter of law and order, might not be taken as it was meant, and Chippy was quite shrewd enough to see that.

And Chippy was puzzled—he was tremendously puzzled. For the life of him, he could not see how two men in a boat were going to successfully attack the river-front of Elliotts' warehouse, and he burned to discover their plan of assault. He shut his eyes, and saw clearly a mental picture of the building. Chippy knew the riverside look of every building as well as he knew the back of his hand; he had spent scores and scores of summer days floating about in anything he could seize upon in the shape of a boat.

Well, he saw a broad, high wall, perfectly flat, turning a gable end to the wide stream, and in that wall he saw a number of windows and one large doorway, above which an arm carrying pulleys was thrust out. Under this doorway barges came when the tide was up, and sank to the mud when it went down. Boxes, bags, bales, were swung up to the doorway by pulley and chain, and so taken into the warehouse. But there was no landing-place of any kind; the wall ran sheer down to the mud.

Now, how were these men going to break in? And at low water, too! Fifteen feet at least of oozy, slimy wall would stand up between the boat and the foot of the doorway; twenty feet to the nearest row of windows. Chippy could not form any idea of their tactics, but he meant to discover them before long.

'Well, I got to move a bit,' said the scout to himself. 'I'll 'ook it down to Ferryman's, and get ready for 'em.'

Still on his bare feet, he slid like a shadow through the darkness, counted the mooring-posts as he went, in order to get his bearings, found the head of the steps running down to the spot he sought, and at the next instant his feet were treading the rough stones of Ferryman's Slip.

Here close beside the water it was not quite so dark; the heavy clouds had broken in the west, and the stars were coming out. In their faint gleam Chippy caught the shine of the oily swells as the water lapped gently against the wharf.

There was always water beside Ferryman's Slip at every state of the tide, and Chippy knew that a bunch of boats would certainly be moored off the boat-builder's yard at the top end of the slip. He went up there, and saw their dark forms on the water. He could step into the nearest, and in a moment he was climbing from one to the other with all the sureness of a born waterman, searching for what he wanted. Luck favoured him: he found it on the outside of a bunch, where he had only to slip the knot of a cord to set it free. It was a little broad boat, blunt in the bows, wide in the stern, the sort of boat you can sit on the side of without oversetting, and very suitable for Chippy's purpose this night.
