The girls did not attempt to interfere. They stood and watched while Diana hauled the little boy up the bank. Perhaps each secretly wished she were capable of such a piece of pluck. Though the tree was tall enough to span the stream, its bole seemed very narrow to form a bridge, and the rounded surface made it all the more slippery; the few branches here and there were of little help. Diana hoisted up her protégé, then going in front of him began to crawl across on her hands and knees, speaking to him all the time, so as to encourage him to follow her. Beneath them the water foamed and roared over the rocks: to slip would mean to be whirled into the depths of a dark pool below. It was a slow progress, but inch by inch they crept along till the most dangerous part was passed, and they had reached comparative safety. The girls cheered when at last Diana scrambled to her feet and lifted Harry on to dry ground. A path led up the side of the gorge, and along this he set off at full speed for home. His preserver stood looking after him for a minute or two, and then she turned to re-cross her perilous bridge. Six hands were stretched out to help her as she completed the venturesome journey.
