A writer in the Asiatic Quarterly Review, not long ago declared that the government salt monopoly of the British Empire in India (since practically abolished, or modified) was a cause of greater evils than those resulting from either opium or alcohol. This claim is based on the idea that a lack of salt by the common people of India tends to a deterioration of blood and consequent loss of life. Asiatic cholera is said to be promoted by the lack of salt in the blood. Men and cattle alike are said to be sufferers from this cause, and the soil is rendered less fertile. Whether this idea is well grounded is a minor matter; that the idea has been in many minds is not to be questioned. Thus it will be seen that in the primitive mind salt and blood have seemed to have common properties, and to be in a sense interchangeable, while the more careful observers in the world of science have rather grown toward this thought than away from it. Be it correct or incorrect, the human mind has never been able to rid itself of the idea. Salt is sometimes used in the rite of blood brotherhood among primitive peoples, as is also wine, both wine and salt being counted the equivalent of blood, and the original and the substitute being sometimes employed together as if to intensify the symbolism. Stanley tells of the use of salt in this rite on the occasion of its performance with Ngalyema in the Congo region.[54] And so again in other cases.[55] [54] _The Congo_, I., 383-385. [55] _Ibid._, II., 21-24, 79-90. It is a common practice in the East to welcome an honored guest to one's house by sacrificing an animal at the doorway, and letting its blood pour out on the threshold, to be stepped over by the guest, as a mode of adoption, or of covenant-making.[56] When such a guest comes unexpectedly, and there is not time to obtain an animal for the welcoming sacrifice, it is customary to take salt and strew it in lieu of blood on the threshold,--salt being thus recognized as the equivalent, or as a representative, of blood.[57] [56] See _Threshold Covenant_, passim. [57] _Ibid._, p. 5; Griffis's _Mikado's Empire_, pp. 467, 470; Isabella Bird's _Untrodden Tracks in Japan_, I., 392. The measure of love and honor accorded to the welcomed guest is indicated by the cost or preciousness of the sacrifice on the threshold. There are traditions, at least, of the sacrifice of a son of the host in this way. Again a favorite horse has been thus sacrificed. More frequently it is a lamb that is the sacrifice. If there is no lamb available, a fowl or a pigeon is thus offered. The essential factor in every case is the blood, the life, outpoured. If, however, no actual blood is obtainable, salt, as representing blood, is accepted as indicating the love and the spirit which prompts the welcome, according to the giver's means. There could hardly be a fuller proof of the identity of salt and blood in the primitive mind.
