We have mentioned some of the many futile attempts made for their conversion; more might be added; for various missions were devised,--by the Society for the Propagation of the Gospel in Foreign Parts, aided by the colonial government; by the Wesleyan and the Church Missionary Societies; and by the London Missionary Society; but none of these met with much success, and we fear all have been in turn abandoned. The mission of Mr. Threlkeld, on the margin of lake Macquarie deserves especial notice. It was continued for upwards of fourteen years; during the first six years at the charges of the London Missionary Society, but owing to the heavy expense, and the slow progress of the mission, they withdrew from it after an outlay of about three thousand pounds. Mr. Threlkeld was reluctant to give up the mission, and pursued it for some time from his own resources and those of his friends, with a small grant of a hundred and fifty pounds a-year from the British government, who also made over ten thousand acres of land to be held on trust on behalf of the natives. Mr. Threlkeld seems to have been admirably fitted for his work; he had been the fellow labourer of the martyr John Williams, of Erromanga, and left the Tahitian mission in consequence of heavy domestic afflictions. He had spent much time in acquiring a knowledge of the language of the "blacks" or aborigines, of which he drew up a grammar, besides translating some portions of Scripture, Watts's hymns, and other suitable works. He had generally three or four tribes resident around him upon the land granted for their use. Occasionally he employed from twelve to sixty of them in burning off the timber and clearing the land, an employment which they liked best. At this they would continue for eight or ten days at a time, until some native custom, or the report of the hostile intention of some neighbouring tribe, called them off, perhaps never to return. Harmless as they seemed, their customs were ferocious; the tribes were constantly at war, and upon human life they set no value; they had no law against murder, and consequently no punishment for it. A man may murder his wife, or child, or any other relative with impunity; but if a person murder another who is no way connected with him, the nearest of kin to the murdered person will sometimes avenge his death; though this seldom happens unless the delinquent and the sufferer are of different tribes. It is only as they become acquainted with the customs of Europeans that human life is regarded. In their native wilds they sport with the sufferings both of man and beast.
