"Read it for me, Sam," he said, "and quick about it. How far behind them do you reckon we are?" "Tree, four hour p'raps. I tell like dis; dese marks here two hour ago, when de rain fall. Dat sartin'; but yo look at de water in de holes. Where de sun able to reach it it almost gone, sucked up into de sky. Dat take little time, longer dan two hour. Under de tree de holes full to de top, 'cos dey dere like de oders when de rain fall, and de sun not able to reach 'em. Dose men travelling quick." "Then so will we. Forward," commanded Jim. "Better go slow and sure than fast and knock up the horses," cautioned Phineas, riding up beside him. "Jim, if you'll take my advice, you'll set a steady pace, and keep going at it for the hour together; then give the animals a rest for ten minutes. In the end we'll cover the ground quicker than those rascals, supposing them to be riding on direct without halting." It was undoubtedly good advice, and our hero took it. He found it hard to curb his impatience, for he was eager to rescue Sadie from such wretches. But he was sensible enough to recognize good advice when it was given, and promptly issued his orders. "See here, Tomkins," he called out. "You come along with the main party. I'll go ahead with Sam, and one of your men can take your place. Then, in case there's need to change our plans, I shall be right at the head and able to stop the party." They pushed on after that at a steady pace, covering ground which for the most part was only thinly studded with bush, and stretched out flat and level before them; but some five miles ahead a range of hills and broken ground cropped up before them, hiding the country beyond. "Perhaps we shall be able to catch a sight of those rascals from the top," thought Jim, as he rode along in a brown study. "In any case there's much to be thankful for. That rainstorm has softened the ground and made it easy to follow; a little more this afternoon, or when the night falls, would give us a fine line for to-morrow." Some two hours later they emerged at the top of the hilly ground, still on the tracks of the fugitives, and at a sign from Sam dropped from their horses. "Stop here," he said at once, raising a warning hand. "Not show up above de skyline, else p'raps dem scum see us. Yo wait little while for me to squint all round; but not t'ink I be able to see um. De bush down dere very dense."
