Next moment there rose, below me, a yell; and I stood where I was, like a man petrified.
For the Captain, having spurred his jaded steed some way into the bog, reined up suddenly, and tried to turn back.

The horse's legs were already sunk to the knees, and in his struggle to get clear plunged yet a yard or two farther towards the middle.

Then he sank miserably on his side, throwing his rider to the ground.

The man, with a wild effort, managed to fling himself on the flank of the fast sinking beast; but 'twas a short-lived support.

With a yell that rings in my ears as I write, he struggled again to his feet and tried to run.
