"We can do as we please by standing firm to our determination of going away in time to take passage on the steamer," he said; "therefore we'll see the adventure through to that point, and if Cummings fails in his purpose of bringing away a large amount of gold we will have had such an experience as can be talked about when we get home."

As for Jake, a glimpse of the glistening walls of the city had literally intoxicated him, and his one and only desire was to reach that point where he could satisfy himself by the sense of touch as well as sight.

As the time drew near for the final move in the bold scheme Cummings became greatly agitated. It was as if all the blood had left his face, and his eyes were open wide and staring as he gazed into vacancy.

"Are you sick?" Teddy asked in alarm.

The young man shook his head.

"I suppose I'm acting like a fool; but can't prevent my nerves from getting the best of me just at this time. After laboring two years for one thing, and then being so near a successful completion of the work, is enough to make any fellow excited."

Teddy was on the point of saying he fancied that fear of the ultimate result might have some share in this alleged nervous attack; but, fortunately, he checked himself in time, and turned to watch Poyor who was hiding the boat beneath an ingeniously constructed screen of leaves.

Night came slowly; the twittering of the birds and the chattering of the monkeys was hushed. Among the dense underbrush the darkness was intense, yet the Indian remained motionless in a listening attitude.

Amid profound silence the moments passed until to the boys it seemed as if it must have been midnight when Cummings whispered:

"It is time. Poyor shall lead the way, and I will bring up the rear."
