The use of hoops of this kind requires practice, and the natives use their bare feet against the tree, which prevents slipping. Harry, however, had shoes; not a very good thing to use against the bark, and after numerous trials both boys found the task a trying one. Their bare feet were too tender to use against the rough bark, and as a last resort one of the old pair of shoes was brought out, and studded with nails.
The climber gets inside the hoop, with the latter around the tree, and resting against the small of the back, or a little higher up. The feet are then braced against the tree, and the hoop grasped by both hands. In climbing the body is suddenly moved toward the tree, and this motion temporarily releases the outward pressure against the hoop, and at the same moment the hoop is moved upwardly about a foot. One or both feet then make an upward step, and this process is repeated.
More than an hour was occupied in learning to manipulate the hoop, so as to progress upwardly, and at the end of that time Harry made a slow and careful ascent to the first limb, a distance of thirty feet, stopping at intervals, as he made his way up, to view the ever-increasing landscape, and to take the needed rest.
"Do you see anything, Harry?" was George's eager questioning, as he moved upwardly.
"Nothing yet," was the invariable reply. When the first limb was reached he seated himself, and had an opportunity to view the surroundings from a far better vantage point.
"Can you see the river?" was the Professor's inquiry.
"It is too hazy to make out anything there. It is clearer to the south."
"What can you see to the southwest?"
Harry scanned the country in that direction for some time before replying. "All I can see there are trees, trees, just like the forest we have been going through; but directly west of us we would have comparatively easy traveling. The forest seems to extend southwest, and we have been traveling through it at an angle. If I could get higher I might have a better view."
He ascended fifteen feet higher, but even at that point the forest hid the view to the southwest.
