It was not easy walking here either; there were darksome murky pools to go round, and brown unwholesome streams to wade through.

Nothing could have been more depressing than the view around him, look where he would.

As far as wild beasts were concerned, the dismal swamp was untenanted. Here were no lordly elephants, no sturdy rhinoceroses, no giraffes towering in their strength, nor deer, nor gnu, nor hartbeeste, nor the herds of swift-footed ambling zebras they had been so used to behold.

But in the great pools, and in the sluggish mud-stained streams, wallowed crocodiles more large and loathsome than Harry could have imagined even in his dreams, while often several of these at one time could be seen on the banks huddled together asleep or basking in the sunshine.

They walked onwards as fast as they could, hardly pausing to eat, but there seemed no end to the horrible fen. It seemed to Harry as if he was bound to go on, and still go on, but never come to anything.

The sun began to set at last, glaring purple through a watery-looking sky.

There was nothing for it but sleep in the swamp till another day dawned. Harry and his men now sought the shelter of a clump of stunted trees which they reached after some difficulty.

While daylight lasted they were careful to beat the bush well before they thought of lighting the camp-fire, for close under the trees in places like this the giant anaconda or python often lies coiled up till roused to fury by the presence of man or other animals.

The sun went down, and gloaming and gloom settled down over the marsh. The very stars seemed to give a feebler light than was their wont, for their rays were shorn by a rising haze.

It took quite a long time to-night to light the camp-fire, for the materials had got damp.
