In many cases these overseers were ex-convicts, and although it might be considered advisable that the master should not make himself too cheap, and that a middleman should be employed to come into direct communion with the convict himself, still every precaution should have been taken to prevent any abuse of power. In point of fact every well-ordered establishment should have been uniformly under the eye of its resident owner. But in reality the lot of the convict in assignment was left altogether to chance. According to his luck in masters, he might be very miserable, or as happy as the day was long: one master might be lenient, giving good food and exacting but little labour in return; another, a perfect fiend. It was quite a lottery into which sort of hands the convict fell, for until 1835 there was little or no inquiry into the character of applicants for servants, and except in the most flagrant cases requisitions were never refused. This, indeed, comprised one of the chief objections to the system of assignment. It was altogether too much a matter of haphazard. No system of penal discipline ought to be left thus to chance; yet as we have seen, there was no supervision and little attempt to enforce hard labour or any stringent code of discipline. This neglect fostered evil courses, and tended to increase the temptations to crime. Nor was the style of labour provided that which was always most suited to the persons for whom it was intended. In some few cases it was proper enough. Men employed as shepherds were perforce compelled to drop into regular habits from being obliged to go out and return with their herds at fixed hours, and they lived much alone. But these were only a small proportion of the whole number, and the balance working in association had many opportunities for developing vicious qualities by this corrupting intercourse. Especially was this the case with the mounted herdsmen, who were free to gallop about the country, collecting together in large numbers at the squatters' huts to drink and gamble and plot schemes of depredation.
