The labourers in husbandry may be divided: 1st, into those who are able to perform the full work of a man; that is, what can be done by a person from twenty-one years of age to fifty. I know no husbandry-work (mowing hardly excepted) that is not equally within the power of all persons within those ages, the more advanced fully compensating by knack and habit what they lose in activity. Unquestionably, there is a good deal of difference between the value of one man's labour and that of another, from strength, dexterity, and honest application. But I am quite sure, from my best observation, that any given five men will, in their total, afford a proportion of labour equal to any other five within the periods of life I have stated; that is, that among such five men there will be one possessing all the qualifications of a good workman, one bad, and the other three middling, and approximating to the first and the last. So that in so small a platoon as that of even five, you will find the full complement of all that five men CAN earn. Taking five and five throughout the kingdom, they are equal: therefore, an error with regard to the equalization of their wages by those who employ five, as farmers do at the very least, cannot be considerable. 2ndly. Those who are able to work, but not the complete task of a day-labourer. This class is infinitely diversified, but will aptly enough fall into principal divisions. MEN, from the decline, which after fifty becomes every year more sensible to the period of debility and decrepitude, and the maladies that precede a final dissolution. WOMEN, whose employment on husbandry is but occasional, and who differ more in effective labour one from another, than men do, on account of gestation, nursing, and domestic management, over and above the difference they have in common with men in advancing, in stationary, and in declining life. CHILDREN, who proceed on the reverse order, growing from less to greater utility, but with a still greater disproportion of nutriment to labour than is found in the second of these subdivisions: as is visible to those who will give themselves the trouble of examining into the interior economy of a poor-house. This inferior classification is introduced to show, that laws prescribing, or magistrates exercising, a very stiff and often inapplicable rule, or a blind and rash discretion, never can provide the just proportions between earning and salary on the one hand, and nutriment on the other: whereas interest, habit, and the tacit convention, that arise from a thousand nameless circumstances, produce a TACT that regulates without difficulty, what laws and magistrates cannot regulate at all. The first class of labour wants nothing to equalize it; it equalizes itself. The second and third are not capable of any equalization.
