Peering over the little parapet which ran round their resting-place, Snap could see camp-fires on the prairie below, and through his glasses he made out a line of sentries set all round the foot of the mountain, not near it, but still hemming it in in such a way that escape from it across the open prairie to the forest beyond the camp-fires was impossible. 'They know that we're trapped,' said Frank, 'and mean to starve us out, though they are still afraid to put foot on the mountain.' 'That's so,' replied Wharton, 'and young Towzer is opening the last tin of meat but one. It must be only one tin between four to-night, and if Warwolf doesn't bring his Blackfeet to-morrow we had better try to run the gauntlet, and get away separately to-morrow evening before hunger makes us too weak to fight.' 'It wouldn't do, Dick,' whispered Snap, drawing him aside, 'Towzer could never get down the mountain, and even if Frank got through he could never find his way in the forest. But I have a better idea than that.' 'What is it, lad?' asked Wharton. 'Never mind yet, old fellow, it will keep,' replied the boy; 'besides, I'm not quite sure yet if it is practicable, and if Warwolf turns up I would much rather not try it. But look here,' he added, turning to the others, 'I've got some interesting reading in this poor old German's log-book.' 'Let us have it after dinner, Snap,' said Frank. 'Them's my sentiments exactly,' put in Dick; 'I never can hear reading comfortably unless I've got a pipe in my mouth.' So after dinner, that is after everyone had played as long as he could with his small share of the last tin but one, Snap took the book and read, whilst Dick smoked a double allowance of tobacco to console his ill-used stomach for the loss of at least three-fourths of his share of the curry, which the good old chap had managed to add to the boys' portions unobserved. 'I don't call it kinder fair on you, boys,' he remarked, 'my doing all the smoking; won't you try a pull? it's wonderfully satisfying.' Snap took the offered pipe and enjoyed the first few whiffs immensely, but, as he remarked, 'almost at once struck ile.' 'Thank you, Dick, kindly,' he said, handing the pipe back hurriedly, 'but I think my jaw will work without oiling. I'd rather read and see you smoke.' Dick laughed and resumed his pipe, while Snap read as follows: '"Sunday, 15.--Thank God, I have still an arm left to write. It is I who am in fault. The balloon was by me too suddenly stopped, and I was at once outthrown, and my leg and arm altogether broken----" 'Then there is a stop, as if the pen had fallen from his hand,' said Snap. 'Fainted from pain, I guess,' said Dick, taking his pipe out of his mouth and blowing away a lot of little rings of smoke. This was a favourite trick of Dick's, and you might see him often send three rings one through the other in succession.
