"The sole object of a price is to prevent labourers from turning into landowners too soon: the price must be sufficient for that one purpose, and no other. The question is, What price would have that one effect? That must depend, first, on what is meant by 'too soon;' or on the proper duration of the term of the labourer's employment for hire; which again must depend upon the rate of the increase of population in the colony, especially by means of immigration, which would determine when the place of a labourer, turning out a landowner, would be filled by another labourer; and the rate of labour-emigration again must depend on the popularity of the colony at home, and on the distance between the mother-country and the colony, or the cost of passage for labouring people. Secondly, what price would have the desired effect, must depend on the rate of wages and cost of living in the colony, since according to these would be the labourer's power of saving the requisite capital for turning into a landowner: in proportion to the rate of wages, and the cost of living, would the requisite capital be saved in a longer or a shorter time. It depends, thirdly, on the soil and climate of the colony, which would determine the quantity of land required (on the average) by a labourer, in order to set himself up as a landowner. If the soil and climate were unfavourable to production, he would require more acres; if it were favourable, fewer acres would serve his purpose: in Trinidad, for example, ten acres would support him well; in South Africa, or New South Wales, he might require fifty or a hundred acres. But the variability in our wide colonial empire, not only of soil and climate, but of all the circumstances on which a sufficient price would depend, is so obvious, that no examples of it are needed. It follows, of course, that different colonies, and sometimes different groups of similar colonies, would require different prices. To name a price for all the colonies, would be as absurd as to fix the size of a coat for mankind.
