'It's strange too,' added Wharton; 'of course they've seen us and know we are dropping like a ripe plum into their mouths, but I wonder at their making such a noise about it. It's not like 'em!'

'Snap,' said Frank, 'I think we can sell them now. If you fellows tied me up a little so as to help my bad arm, we could all hold on to the ring above the car or the cords it is fastened to, and cut the car adrift.'

I suppose most of my readers have seen a big balloon—if not, a word of explanation may be necessary here. The body of the balloon is, of course, a great sack or bag of some excessively fine and light material, such as silk, or layers of india-rubber, between sheets of linen covered with thick coats of varnish. Over the balloon is a kind of net-work of rope. This is its harness and comes to a point towards the bottom, where all the ropes are attached to a great wooden hoop, from which again hang the ropes to which the car itself is attached. Frank's idea was to climb up into the ring and cut the car adrift.

'You've hit the nail on the head, my lad, plum centre this time,' said Wharton, 'but can you get up to the ring yourself?'

'I'll try,' replied Frank, 'but there isn't a moment to lose. Give me a hand, Towzer.'

Between them the others got Frank up into the rigging of the balloon, and tied him securely to the ring, so that he would not be entirely dependent upon his one arm for support.

'Are you all right?' cried Snap from his perch.

'All right, old chap.'

'All right,' came the answers.

'Then cut the ropes near you all together, so as not to drag the balloon, over on one side,' he cried. 'Now!'
