out difficulty that they broke a path through the thickets and brushwood which had never been put aside by the hand of man, 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 anyone. 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. 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 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. When each one was about to give himself up to sleep, Cyrus Harding drew from his pocket little specimens of different sorts of minerals, and said, "My friends, this is iron mineral, this a pyrite, this is clay, this is lime, and this is coal. Nature gives us these things. It is our business to make a right use of them. To-morrow we will commence operations."
