These reports were, indeed, constantly circulated, and tended to damp the ardour and diminish the vigilance of the line. Some scouring parties from Norfolk Plains fell in with a tribe of forty, whom they pursued beyond the Shannon. They followed them for three days, but were compelled to return: the blacks, in their progress, had surprised a settler, and murdered him. The rumours of escape were aggravated by imagination: a party of the whites were seen by some sawyers, who ran away and reported them as natives; and it was several days before they could be persuaded of their error.
The settlers, worn out with fatigue and longing for their homes, were impatient to advance, and afforded ample opportunities for concealment and escape. Among the rest a place is noticed, which enabled the natives to defy intrusion or discovery, near the "Three Thumbs' Mountain,"--an almost impenetrable forest, of seven miles extent: the spreading branches obscure the sky, and lofty plants grow entwined, and conceal an object at the distance of a few feet. The attempt of the blacks to cross the line discovered their retreat. It was resolved to assemble forces sufficient to surround, break through, and storm this thicket: it was penetrated by about 300 men, who kept up a constant fire of musketry. A party, hearing the rustling of leaves like the noise of cattle, followed the sound: they came up to an encampment, where the fires were unextinguished, and where half-formed weapons indicated a hasty dispersion. Here they found the impression of nails, and what were deemed sure proofs of a superior directing intelligence. The presumption, that some convicts were incorporated with the blacks, was certainly strong, but it was probably but a temporary or casual intercourse, of not much utility to the natives. The Governor had, however, a full conviction that to this circumstance the failure might be partly ascribed. In the middle of the march, he ordered the publication of a report, which appeared decisive of the fact. Savage, a servant of Mr. Bisdee, was met half naked by the Governor, near Mills' Lagoon, to whom he stated he had been surrounded by a tribe, and rescued from violence by a man named Brown, who was with them. This person he had known in gaol. Savage advised Brown to bring in the natives, but he refused: he said that he had been frequently at Hobart Town, where he had bought clothes for the women: he had a double-barrelled gun, and seemed to have complete control over them. They carried Savage with them as far as Mills' Lagoon, when he was told he might go. The Governor and his party instantly set off in the pursuit, but they discovered no traces of the natives. The truth of this narrative has been questioned, yet from the number of points in which a correct memory, or extraordinary powers of invention would be requisite, the Governor might have easily detected imposition. The man stated that fright cured him of rheumatism; his rags were consistent with his story. It is, however, the only clear testimony to the presence of white men with the blacks at that period.
