m the sea, which undoubtedly was to the east, or, possibly,
northeast. West River flowed to the north, and all the streams crossed
flowed north or northeasterly, how far, it was impossible to say.

Two days afterward the scene changed somewhat. There had been little
wind during the journey thus far; but now breezes sprang up for two
successive days, at about four in the afternoon, which came from the
north.

"I think the sea is not far away."

"Why do you think so, Professor?"

"Did you notice the warm breezes this evening, and also last night at
about the same time?"

"Why should the breezes from the ocean blow warm winds to us at this
time of the year when it ought to be cold?"

"It is not at all likely that the breezes are any warmer than at other
times of the year. Heat is merely a relative matter. We feel the
difference of the wind temperatures principally for the reason that when
the vast body of water in moving ocean streams is giving off its heat,
it imparts it to the atmosphere and modifies it, so that as it sweeps
over the land it is warmer than the natural temperature."

The following day, late in the afternoon, they caught the first glimpse
of the sea, and it was welcomed. A camp was made for the night in the
open, and with an early start next morning the explorers reached the
last hill to the west of the cataract.

When they arrived home, which was not without considerable misgiving,
owing to their long absence, they were overjoyed at finding everything
at the house in perfect order, but their yaks were missing.

This was, at first, a sore grief to them, especially to George, who
considered it to be a personal loss. Milk was a luxury, as well as a
necessity, to him. The team was now all that remained of their herd.

"It is strange we did not see any of them on our journey."

It was a surprising thing to see their water wheel in motion, although
they had taken considerable pains to push the wheel back so the blades
would not be in contact with the water. It was found that the Cataract
River was much swollen with the rains, so that the water had come into
contact with the wheel.

As the team was now the sole reliance, so far as the herd was concerned,
the Professor suggested that they should thereafter keep the team within
the enclosure, so as to prevent their straying, as they might, in the
absence of their fellows, try to escape.

The present house, which had been built since coming to the Ca
