Indians was the model of the covenant with the tribe of Dutegaller. They conveyed a track of 600,000 acres, for blankets and other objects of native desire, and an annual payment of similar articles to the value of L200. This deed was signed, sealed, and delivered by the natives in due form. The report of this expedition was presented to Arthur, who warmly concurred in the occupation, and approved the consideration of native rights; but observed that those rights had been disregarded in the recent colonisation of South Australia, and that Port Phillip was within the government of New South Wales. Arthur was desirous of making that territory dependent on Van Diemen's Land. The minister favorably noticed the proposal; but in the meantime Governor Bourke asserted his claim, and declared the company intruders, and their bargains with the natives void. Notwithstanding, the colony now opened was occupied by many adventurers. Their sheep were rapidly transferred, and the greater portion of the early inhabitants were settlers from Van Diemen's Land. The settlement was suffered with reluctance. The theory of concentration had been adopted only a few months before; but, except by setting up a government on the spot, it was found that an illegal occupation of land could not be prevented. Governor Bourke wrote to the secretary of state, that whatever the general wisdom of concentration, an opposite course was necessary for pastoral wealth; and that to neglect nutritious food, would be to reject "the bounty of providence." He proposed to sell the land in townships, and employ the proceeds in the public service. Lord Glenelg confessed that the scheme of concentration was not of universal application: that Lord Ripon's regulations were not everywhere desirable, and that it was proper to tolerate the ardour of private enterprise; to moderate its course, and gather up its fruits. The Dutegaller association was dissolved; but not until they had given an impulse to colonisation, more rapid than any example offered by history. This peaceable occupation, contrasted with the cruelties inflicted at Twofold Bay--a whaling station, now rising into a province. While these plans of colonisation were in progress, the social condition of the penal colonies was constantly discussed. To correct the evils admitted on the spot, and to obviate the dangers apprehended at home, it was determined by the ministers to promote the emigration of mechanics and females. One series of plans were proposed for New South Wales and Van Diemen's Land, and with the same general results. The policy of government required the emigration of free mechanics.
