The Wealth of Nations_ Books 4-5 - Adam Smith [184]
An army of hunters can seldom exceed two or three hundred men. The precarious subsistence which the chase affords could seldom allow a greater number to keep together for any considerable time. An army of shepherds, on the contrary, may sometimes amount to two or three hundred thousand. As long as nothing stops their progress, as long as they can go on from one district, of which they have consumed the forage, to another which is yet entire, there seems to be scarce any limit to the number who can march on together. A nation of hunters can never be formidable to the civilised nations in their neighbourhood. A nation of shepherds may. Nothing can be more contemptible than an Indian war in North America. Nothing, on the contrary, can be more dreadful than a Tartar invasion has frequently been in Asia. The judgment of Thucydides, that both Europe and Asia could not resist the Scythians united, has been verified by the experience of all ages. The inhabitants of the extensive but defenceless plains of Scythia or Tartary have been frequently united under the dominion of the chief of some conquering horde or clan, and the havoc and devastation of Asia have always signalised their union. The inhabitants of the inhospitable deserts of Arabia, the other great nation of shepherds, have never been united but once; under Mahomet and his immediate successors. Their union, which was more the effect of religious enthusiasm than of conquest, was signalised in the same manner. If the hunting nations of America should ever become shepherds, their neighbourhood would be much more dangerous to the European colonies than it is at present.
In a yet more advanced state of society, among those nations of husbandmen who have little foreign commerce, and no other manufactures but those coarse and household ones which almost every private family prepares for its own use, every man, in the same manner, either is a warrior or easily becomes such. They who live by agriculture generally pass the whole day in the open air, exposed to all the inclemencies of the seasons. The hardiness of their ordinary life prepares them for the fatigues of war, to some of which their necessary occupations bear a great analogy. The necessary occupation of a ditcher prepares him to work in the trenches, and to fortify a camp as well as to enclose a field. The ordinary pastimes of such husbandmen are the same as those of shepherds, and are in the same manner the images of war. But as husbandmen have less leisure than shepherds, they are not so frequently employed in those pastimes. They are soldiers, but soldiers not quite so much masters of their exercise. Such as they are, however, it seldom costs the sovereign or commonwealth any expense to prepare them for the field.
Agriculture, even in its rudest and lowest state, supposes a settlement: some sort of fixed habitation which cannot be abandoned without great loss. When a nation of mere husbandmen, therefore, goes to war, the whole people cannot take the field together. The old men, the women and children, at least, must remain at home to take care of the habitation. All the men of the military age, however, may take the field, and, in small nations of this kind, have frequently done so. In every nation the men of the military age are supposed to amount to about a fourth or a fifth part of the whole body of the people. If the campaign, too, should begin after seed-time, and end before harvest, both the husbandman and his principal labourers can be spared from the farm without much loss. He trusts that the work which
