habit of observing everything and thinking about it gives its
possessor. For this reason he took pains to make no display of his
knowledge of Latin or of anything else which they had no chance to
learn. He wanted them to learn to use their eyes, their ears and their
heads, knowing very well that the greater as well as the better part
of education comes by observation and thinking, rather than from
books.

Just now he was striding forward as rapidly as he could, as it was
beginning to rain.

"Keep your eye on the hind sight boys, and don't lose it," he cried;
"we must hurry or we shall be caught in a pocket to-night."

Hour after hour they marched, the rain pouring down steadily, and the
ground becoming every moment softer. The walking wearied them
terribly, but they pushed on in the hope that they might be able to
cross the upper waters of the Nepalgah river before night. This would
place them on the west bank of that stream, where Sam believed that he
should find the marching tolerable. If they should fail in this, Sam
feared that the water would rise during the night, and fill all the
bottom lands. In that event he must continue marching down the east
bank of the river; not going very far out of his way, it is true, but
having to pass through what he was satisfied must be a much more
difficult country than that on the other side.

Night came at last, and they were yet not within sight of the stream,
notwithstanding their utmost exertions. Sam called a halt just before
dark, and selected a camping place.
