Now Chippy scratched his jaw thoughtfully. There was the boat, but oars and rowlocks were safely locked up in the builder's shed. This would have stumped some people, but not Chippy. Often and often he had been able to get hold of a boat, but nothing else. He was quite familiar with the task of rigging up something to take the place of an oar. He hopped across the boats, gained the shore, and sought the boat-builder's shed. Around such a place lie piles of planks, broken thwarts, broken oars, odds and ends of every kind relating to boats, new or old. Chippy knew the shed, and sought the back.
'Old Clayson used to chuck a lot o' stuff at the back 'ere,' thought Chippy. 'I wish I durst strike a match, but that 'ud never do. They might see it.' So he groped and groped with his hands, and could hardly restrain a yell of delight when his fingers dropped on a smooth surface, broken by one sharp rib running down the centre.
'A sweep!' Chippy cried to himself joyously—'an old sweep! Now, if theer's on'y a bit o' handle to it, I'm right.'
With the utmost caution he drew the broken sweep from the pile of odds and ends where it lay. Yes, there was a piece of handle, and Chippy made at once for his boat, carrying his prize with him. An oar would have suited him much better, but beggars must not be choosers. The fragment of the sweep was heavy and clumsy, but in Chippy's skilled hands it could be made to do its work.
These preparations had taken some time, and Chippy was about to try his piece of sweep in the scull-notch in the stern when he paused and crouched perfectly still on the thwart. They were coming. He heard movements on the stone stairs which ran down to the river. The scout put his head over the side of the boat and listened. Water carries sound as nothing else does, and he heard them get into their boat very cautiously, slip oars into rowlocks, and paddle gently away. There was no dip or splash from the oars. 'Muffled 'em,' said Chippy to himself.
He gave them a couple of minutes to get clear out into the river from the side channel which washed the slip; then he prepared to follow. He untied the painter, pushed his boat clear of its companions, slipped his sweep over the stern, and began to scull down the channel without a sound, his practised hands working the boat on by the sweep as silently and smoothly as a fish glides forward by the strokes of its tail.
The little skiff slipped out on to the broad bosom of the river, and Chippy looked eagerly ahead. He saw his men at once. They were paddling gently down-stream close inshore. At this point the river ran due west, ran towards the quarter of the sky now bright with stars. Against this brightness Chippy saw the dark mass of boat and men. He glanced over his shoulder. The east remained black, its covering of cloud unbroken, and Chippy felt the joy of the scout who follows steadily, and knows that he himself is unseen.
The boat ahead went much faster than Chippy's little tub, but he let them go, and sculled easily forward; he knew where to find them. As they approached Elliotts' warehouse, a great cloud drew swiftly over the west, and the scout completely lost sight of the other boat. But the darkness was short. Within a few minutes the cloud passed as swiftly as it had come, and the surface of the river was once more pallid in the starshine.
Chippy saw the great bulk of the warehouse emerge from the gloom; he saw the level plain of water, now smooth at this time of dead-slack, and he expected to see the boat, but he did not. He brought up his skiff with a sharp turn of the sweep, and rubbed his eyes, and looked, and looked again. He saw nothing. The boat had vanished. It was not lying off the warehouse; of that he was quite sure. He was so placed, fairly close inshore, that his eye swept every inch of water along the front of the building. No boat was there.
