But he reflected that he had only obeyed the orders of Ziffak, who indeed would not have permitted his wishes to be disregarded, for who should know the wisest course so well as he? Besides, his own reason told him that if the Professor and his companion were attacked in the cabin, it was impossible for him to raise a finger in their behalf.

And so he dismissed that phase of the marvellous business from his mind and faced the present situation.

He had fled with Ariel from her father, King Haffgo. Instead of turning to the northward down the Xingu, they had gone further up the stream and directly away from the right course out of the perilous country.

But while, in one sense, this might be looked upon as the height of recklessness, he saw it was unavoidable. Had they turned down the Xingu, there would have been no escaping their foes, while the enchanted lake and its surroundings must afford secure shelter for a time.

But for how long?

That was the question which obtruded itself, even while filled with the delightful thrill of his new love, and when en rapport with his marvellous surroundings.

The intimate knowledge which Ariel possessed of the region would guide them to some spot where they could reasonably hope to be safe from pursuit, unless such pursuit was led by her enraged parent.

Ashman was still scrutinizing the great mass of rock, steadily assuming more definite shape in the moonlight as the intervening distance decreased, when he was surprised that he had not noticed the mountainous elevation behind it. The immense rock seemed but the beginning of others rising beyond to the height of a thousand feet, while they broadened to the right and left until they stretched over an extent of several miles.

It seemed to him that these constituted a spur of the Geral range, which extend in a northwesterly direction between the Guapore River (forming a part of the eastern boundary of Bolivia) and the headwaters of the Tapajos and Xingu. If so, their extent was continuous for a hundred miles.

Ashman had ceased paddling, though, under the faint momentum remaining, the canoe continued slowly moving over the lake and gradually drawing near the rock. He did not break the silence, but asked himself what could be the reason of Ariel's direction for him to paddle toward the rock. He supposed there was some place of concealment which she had in mind, though he discerned nothing of that nature.
