Ontario in our own times has been the scene of important naval evolutions. Fleets have manoeuvered on those waters, which, half a century ago, were as deserted as waters well can be; and the day is not distant when the whole of that vast range of lakes will become the seat of empire, and fraught with all the interests of human society. A passing glimpse, even though it be in a work of fiction, of what that vast region so lately was, may help to make up the sum of knowledge by which alone a just appreciation can be formed of the wonderful means by which Providence is clearing the way for the advancement of civilization across the whole American continent. THE PATHFINDER. CHAPTER I. The turf shall be my fragrant shrine; My temple, Lord! that arch of thine; My censer's breath the mountain airs, And silent thoughts my only prayers. MOORE The sublimity connected with vastness is familiar to every eye. The most abstruse, the most far-reaching, perhaps the most chastened of the poet's thoughts, crowd on the imagination as he gazes into the depths of the illimitable void. The expanse of the ocean is seldom seen by the novice with indifference; and the mind, even in the obscurity of night, finds a parallel to that grandeur, which seems inseparable from images that the senses cannot compass. With feelings akin to this admiration and awe--the offspring of sublimity--were the different characters with which the action of this tale must open, gazing on the scene before them. Four persons in all,--two of each sex,--they had managed to ascend a pile of trees, that had been uptorn by a tempest, to catch a view of the objects that surrounded them. It is still the practice of the country to call these spots wind-rows. By letting in the light of heaven upon the dark and damp recesses of the wood, they form a sort of oases in the solemn obscurity of the virgin forests of America. The particular wind-row of which we are writing lay on the brow of a gentle acclivity; and, though small, it had opened the way for an extensive view to those who might occupy its upper margin, a rare occurrence to the traveller in the woods. Philosophy has not yet determined the nature of the power that so often lays desolate spots of this description; some ascribing it to the whirlwinds which produce waterspouts on the ocean, while others again impute it to sudden and violent passages of streams of the electric fluid; but the effects in the woods are familiar to all. On the upper margin of the opening, the viewless influence had piled tree on tree, in such a manner as had not only enabled the two males of the party to ascend to an elevation of some thirty feet above the level of the earth, but, with a little care and encouragement, to induce their more timid companions to accompany them. The vast trunks which had been broken and driven by the force of the gust lay blended like jack-straws;
