They were by no means unnecessary, however, for any imprudence or carelessness might have cost the travelers dear. Others beside Glenarvan were on their guard. In lonely settlements and on stations, the inhabitants and the squatters prepared carefully against any attack or surprise. Houses are closed at nightfall; the dogs let loose inside the fences, barked at the slightest sound. Not a single shepherd on horseback gathered his numerous flocks together at close of day, without having a carbine slung from his saddle.
The outrage at Camden Bridge was the reason for all this, and many a colonist fastened himself in with bolts and bars now at dusk, who used to sleep with open doors and windows.
The Government itself displayed zeal and prudence, especially in the Post-office department. On this very day, just as Glenarvan and his party were on their way from Kilmore to Heathcote, the mail dashed by at full speed; but though the horses were at a gallop, Glenarvan caught sight of the glittering weapons of the mounted police that rode by its side, as they swept past in a cloud of dust. The travelers might have fancied themselves back in those lawless times when the discovery of the first gold-fields deluged the Australian continent with the scum of Europe.
A mile beyond the road to Kilmore, the wagon, for the first time since leaving Cape Bernouilli, struck into one of those forests of gigantic trees which extend over a super-fices of several degrees. A cry of admiration escaped the travelers at the sight of the eucalyptus trees, two hundred feet high, with tough bark five inches thick. The trunks, measuring twenty feet round, and furrowed with foamy streaks of an odorous resin, rose one hundred and fifty feet above the soil. Not a branch, not a twig, not a stray shoot, not even a knot, spoilt the regularity of their outline. They could not have come out smoother from the hands of a turner. They stood like pillars all molded exactly alike, and could be counted by hundreds. At an enormous height they spread out in chaplets of branches, rounded and adorned at their extremity with alternate leaves. At the axle of these leaves solitary flowers drooped down, the calyx of which resembles an inverted urn.
Under this leafy dome, which never lost its greenness, the air circulated freely, and dried up the dampness of the ground. Horses, cattle, and wagon could easily pass between the trees, for they were standing in wide rows, and parceled out like a wood that was being felled. This was neither like the densely-packed woods choked up with brambles, nor the virgin forest barricaded with the trunks of fallen trees, and overgrown with inextricable tangles of creepers, where only iron and fire could open up a track. A grassy carpet at the foot of the trees, and a canopy of verdure above, long perspectives of bold colors, little shade, little freshness at all, a peculiar light, as if the rays came through a thin veil, dappled lights and shades sharply reflected on the ground, made up a whole, and constituted a peculiar spectacle rich in novel effects. The forests of the Oceanic continent do not in the least resemble the forests of the New World; and the Eucalyptus, the "Tara" of the aborigines, belonging to the family of MYRTACEA, the different varieties of which can hardly be enumerated, is the tree _par excellence_ of the Australian flora.
The reason of the shade not being deep, nor the darkness profound, under these domes of verdure, was that these trees presented a curious anomaly in the disposition of the leaves. Instead of presenting their broad surface to the sunlight, only the side is turned. Only the profile of the leaves is seen in this singular foliage. Consequently the sun's rays slant down them to the earth, as if through the open slants of a Venetian blind.
Glenarvan expressed his surprise at this circumstance, and wondered what could be the cause of it. Paganel, who was never at a loss for an answer, immediately replied:
"What astonishes me is not the caprice of nature.
