The explorers had arrived on the western shore of Lake Grant.  The place was well worth looking at.  This extent of water, of a circumference of nearly seven miles and an area of two hundred and fifty acres, reposed in a border of diversified trees.  Towards the east, through a curtain of verdure, picturesquely raised in some places, sparkled an horizon of sea.  The lake was curved at the north, which contrasted with the sharp outline of its lower part.  Numerous aquatic birds frequented the shores of this little Ontario, in which the thousand isles of its American namesake were represented by a rock which emerged from its surface, some hundred feet from the southern shore.  There lived in harmony several couples of kingfishers perched on a stone, grave, motionless, watching for fish, then darting down, they plunged in with a sharp cry, and reappeared with their prey in their beaks.  On the shores and on the islets, strutted wild ducks, pelicans, water-hens, red-beaks, philedons, furnished with a tongue like a brush, and one or two specimens of the splendid menura, the tail of which expands gracefully like a lyre.

As to the water 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 mm, 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.
