In another three hours, they found that the path was descending into a deep and narrow valley.  On the way they passed many of the fetish signs, so terrible to the negro’s imagination.  Pieces of blue string, with feathers and rags attached to them, were stretched across the path.  Clumps of feathers hung suspended from the trees.  Flat stones, with berries, shells, and crooked pieces of wood, were nailed against the trunks of the trees.

At first the four negro boatmen showed signs of terror on approaching these mysterious symbols, and grew pale with fright when Frank broke the strings that barred the path; but when they saw that no evil resulted from the audacious act, and that no avenging bolt fell upon his head, they mustered up courage, and in time even grinned as the sailors made jeering remarks at the mysterious emblems.

As soon as they began to descend into the valley, and it was evident that they were nearing their destination, Frank halted.

“Now, Dominique, do you object to go down and find out all about it?  I am quite ready to go, but you are less likely to be noticed than I am.  There is no hurry, for we don’t wish to move until within an hour of sunset, or perhaps two hours.  There is no fear of our meeting with any interruption until we get back to the point where we started this morning, and it would be as well, therefore, to be back there just before dark.”

“Me go, sar.  Me strip.  Dat best; not seen so easy among de trees.”

“Quite right, Dominique.  What we want to find out is the exact position of the camp and the hut, for no doubt they built a hut of some sort, where Miss Greendale is; and see how we can best get as close to it as possible.  Then it would be as well to find out what sort of village this Obi man has got, and how many men it probably contains.  But don’t risk anything to do this.  Our object is to surprise Carthew’s camp, and we must take our chance as to the blacks.  If you were seen, and an alarm given, Carthew might carry Miss Greendale off again.  So don’t mind about the Obi village, unless you are sure that you can obtain a view of it without risk of being seen.”

“Me manage dat, sar,” the negro said, confidently.  “Dey not on de lookout.  Me crawl up among de trees and see eberyting; no fear whatsomeber.”

Dominique stripped and started down the path, while the rest retired into the shelter of the trees.  An anxious two hours passed, the party listening intently for any sound that might tell of Dominique’s being discovered.  All, however, remained quiet, except that they were once or twice startled by the loud beating of a drum, and the deep blasts from the fetish horn.  At the end of that time there was a general exclamation of relief as Dominique stepped in from among the trees.

“Well, Dominique, what have you found?” Frank exclaimed as he started to his feet.
