ater of the lake, it was sweet, limpid, rather dark, and from
certain bubblings, and the concentric circles which crossed each other
on the surface, it could not be doubted that it abounded in fish.

"This lake is really beautiful!" said Gideon Spilett. "We could live on
its borders!"

"We will live there!" replied Harding.

The settlers, wishing to return to the Chimneys by the shortest way,
descended towards the angle formed on the south by the junction of
the lake's bank. It was not without difficulty that they broke a path
through the thickets and brushwood which had never been put aside by the
hand of men, and they thus went towards the shore, so as to arrive at
the north of Prospect Heights. Two miles were cleared in this direction,
and then, after they had passed the last curtain of trees, appeared the
plateau, carpeted with thick turf, and beyond that the infinite sea.

To return to the Chimneys, it was enough to cross the plateau obliquely
for the space of a mile, and then to descend to the elbow formed by
the first detour of the Mercy. But the engineer desired to know how
and where the overplus of the water from the lake escaped, and the
exploration was prolonged under the trees for a mile and a half towards
the north. It was most probable that an overfall existed somewhere, and
doubtless through a cleft in the granite. This lake was only, in short,
an immense center basin, which was filled by degrees by the creek, and
its waters must necessarily pass to the sea by some fall. If it was so,
the engineer thought that it might perhaps be possible to utilize this
fall and borrow its power, actually lost without profit to any one.
They continued then to follow the shores of Lake Grant by climbing the
plateau; but, after having gone a mile in this direction, Cyrus Harding
had not been able to discover the overfall, which, however, must exist
somewhere.

It was then half-past four. In order to prepare for dinner it was
necessary that the settlers should return to their dwelling. The little
band retraced their steps, therefore, and by the left bank of the Mercy,
Cyrus Harding and his companions arrived at the Chimneys.

The fire was lighted, and Neb and Pencroft, on whom the functions of
cooks naturally devolved, to the one in his quality of Negro, to the
other in that of sailor, quickly prepared some broiled agouti, to which
they did great justice.

The repast at length terminated; at the moment when each one
