Very soon the flight of Ariel must be discovered, and her infuriated father would stop at nothing to punish the elopers. He could command hundreds of the most valiant warriors of the Matto Grosso, and any one, except such a lover as Fred Ashman, would have shrunk from the prodigious task before him.

When the flight of the canoe had continued for several minutes, and he could breathe a little more freely, he asked of his companion, whether she was familiar with the region they expected to visit.

The reply was singular. King Haffgo was accustomed to make regular excursions to the wonderful place, and he rarely did so without Ariel as his companion. He had guards stationed night and day to watch for the approach of strangers, for there was wealth enough to awaken the avarice even of the Emperor of Brazil himself.

Leaving his warriors at the entrance to the lake, with instructions to prevent any one following him, Haffgo would paddle the frail craft out upon the lake, with his daughter as his only companion.

They explored much of the strange locality, visiting places unknown, so far as they were aware, to every one else.

Ashman reflected that this was extremely fortunate so far as Ariel was concerned, for it gave her the very knowledge that was so necessary in their flight; but, unfortunately, their bitterest and most unrelenting enemy possessed the same knowledge.

Now the Xingu broadened, and the flow became still more moderate. Ashman held his paddle suspended and looked around.

"Are we entering the lake?"

"Not yet," she replied with a shake of her lovely head.

The oar was dipped again, and the light boat shot forward like a water fowl over the smooth surface.
