This unhappy turn of affairs has been attended with a double disadvantage. In the first place, the vast increase in the number of convicts sent to Sydney, compared with the small number of free settlers, has for a long time past rendered the continuance of the assignment system impossible; and _the gang system_, to take off and embody the surplus numbers, became in a manner a matter of necessity. The manners of the colony, its habits, its prospects, its morality, have been seriously damaged by this change. The emancipated convicts who have made money, known by the name of "canary birds," have pressed upon the heels, and come to excite the jealousy, of the free settlers. The accumulation of convicts in the lower walks of life has checked the immigration of free labour, perpetuated the frightful inequality of the sexes, and led to the most lamentable disorders. The gang system, of necessity introduced, because free settlers did not exist to take the convicts off under the assignment system, perpetuated in the colony the vices of the hulks, the depravity of the galleys. The whole benefits of transportation to the convicts, their whole chances of amendment, are lost, when, instead of being sent to rural labour in the solitude of the woods and the prairies, they are huddled together, in gangs of four or five hundred, without hope to counterbalance evil propensities, or inducement to resist the seduction of mutual bad example. These evils were so sensibly felt, and led to such energetic representations to the government at home, that at length the colony was pacified, but at the same time its progress checked, by an order in council in 1837, that no more convicts, for a limited time, should be sent to Sydney or its dependencies.
