The causes of their diminution in Tasmania have been already stated; but some of these continued their operation even after the capture: their natural consequences followed. Towards the last days of their savage life, the sexes were disproportionate, although the balance was partly restored by associating the women who had been longer in captivity, with the men whose wives had died; but many of these women had become licentious, and by an extraordinary oversight the government permitted unmarried convicts and others to have them in charge, or to assist in the preliminary labor of their establishment: the result need not be told. The infant children had perished, by the misery or contrivance of their parents: thus in 1838, of eighty-two there were only fourteen children, and of the remainder, eight had attained the usual term of human life: many who surrendered, were exhausted by sickness, fatigue, and decripitude. They were the worn out relics of their nation, and they came in to lie down and die.
The assumption of clothing occasioned many deaths: they were sometimes drenched with rain--perspiration was repressed, and inflammatory diseases followed: the licentiousness, and occasional want of the few last years, generated disorders, which a cold brought to a crisis. Among savages, the blanket has sometimes slain more than the sword: it destroyed the Indian of North America, and even threatened the New Zealander with a similar fate.[24] The abundant supply of food, and which followed destitution, tended to the same result: it was a different diet. The habits of the chase were superseded, and perhaps discouraged: the violent action to which they had been accustomed; the dancing, shouting, hurling the waddy and the spear--climbing for the opossum--diving, and leaping from rock to rock--assisted the animal functions, and developed muscular power. To continue them required the occasion, as well as the permission; but the stimulus was gone.
It is said, by writers not favorable to the establishment at Flinders', that attempts to force the customs and habits of a civilised people were unreasonably, and even ridiculously severe. However docile the blacks, and generous the intention of their teachers, the physical effects of a total change in the habits of a race are not to be disputed, or that what may be harmless when the result of choice, and founded on new mental and physical stimulants, is dangerous when the mind is vacant, and the objects of civilised exertion unappreciated. Perhaps, no one is blameable. In their social circumstances, we may indeed trace the occasion of decay, but they were no longer produced by cruelty.
