This distribution of the whole people into four classes only, and the appropriation of them to four species of employment,—an arrangement which, in the very simple state of society in which it must have been introduced, was a great step in improvement,—must have become productive of innumerable inconveniences, as the wants of society multiplied. The bare necessaries of life, with a small number of its rudest accommodations, are all it prepares to meet the desires of man. As those desires speedily extend beyond such narrow limits, a struggle must have early ensued between the first principles of human nature and those of the political establishment. The different castes were strictly commanded to marry with those only of their own class and profession; and the mixture of the classes from the union of the sexes was guarded against by the severest laws.[19] This was an occurrence, however, which laws could not prevent. Irregularities took place; children were born, who belonged to no caste, and for whom there was no occupation. No event could befall society more calamitous than this. Unholy and infamous, on account of that violation of the sacred law to which they owed their unwelcome birth, those wretched outcasts had no resource for subsistence, excepting either the bounty of the established classes, to whom they were objects of execration and abhorrence; or the plunder of those same classes, a course to which they would betake themselves with all the ingenuity of necessitous, and all the atrocity of much injured, men. When a class of this description became numerous, they must have filled society with the greatest disorders. In the preface of that compilation of the Hindu Laws, which was translated by Mr. Halhed, it is stated that, after a succession of good kings, who secured obedience to the laws, and under whom the people enjoyed felicity, came a monarch evil and corrupt, under whom the laws were violated, the mixture of the classes was perpetrated, and a new and impious race were produced. The Brahmans put this wicked king to death, and, by an effort of miraculous power, created a successor endowed with the most excellent qualities. But the kingdom did not prosper, by reason of the Burren Sunker, so were this impure brood denominated; and it required the wisdom of this virtuous king to devise a remedy. He resolved upon a classification of the mixed race, and to assign them occupations. This, accordingly, was the commencement of arts and manufactures. The Burren Sunker became all manner of artisans and handicrafts; one tribe of them weavers of cloth, another artificers in iron, and so on in other cases, till the subdivisions of the class were exhausted, or the exigencies of the community supplied.
Thus were remedied two evils at once. The increasing wants of an improving society were provided for; and a class of men, the pest of the community, were converted to its service. This is another important era in the history of Hindu society; and having reached this stage, it does not appear that it has made, or that it is capable of making, much further progress. Thirty-six branches of the impure class are specified in the sacred books, of whom and of their employments it would be tedious and useless to present the description. The highest is that sprung from the conjunction of a Brahman with a woman of the Kshattriya class whose duty is the teaching of military exercises. The lowest of all is the offspring of a Sudra with a woman of the sacred class. This tribe are denominated Chandalas, and are regarded with great abhorrence. Their profession is to carry out corpses, to execute criminals, and perform other offices, reckoned to the last degree unclean and degrading. If, by the laws of Hindustan, the Sudras are placed in a low and vile situation, the impure and mixed classes are placed in one still more odious and degrading. Nothing can equal the contempt and insolence to which it is the lot of the lowest among them to see themselves exposed. They are condemned to live in a sequestered spot by themselves, that they may not pollute the very town in which they reside. If they meet a man of the higher castes, they must turn out of the way, lest he should be contaminated by their presence.
