Sindhu.--The Sindhuvallu (drummers) are Madigas, who go about acting scenes from the Ramayana or Mahabharatha, and the story of Ankamma. Sindhu also occurs as a gotra of Kurni. The beating of the drum called sindhu is, I gather, sometimes a nuisance, for a missionary writes to the paper enquiring whether there is any order of Government against it, as the practice "causes much crime, and creates extra work for police and magistrates. Village officials believe they have no authority to suppress it, but there are some who assert that it is nominally forbidden." Singamu-varu.--Singam is described, in the Madras Census Report, 1901, as a class of beggars, who beg only from Sales. They are, however, described by Mr. C. Hayavadana Rao as a class of itinerant mendicants attached to the Devangas. "The name," he writes, "is a variant of Simhamu-varu, or lion-men, i.e., as valourous as a lion. They are paid a small sum annually by each Devanga village for various services which they render, such as carrying fire before a Devanga corpse to the burial-ground, acting as caste messengers, and cleaning the weaving instruments." Sinnata (gold).--An exogamous sept of Kuruba. Siolo.--A small class of Oriya toddy-drawers, whose touch conveys pollution. The Sondis, who are an Oriya caste of toddy-sellers, purchase their liquor from the Siolos. Sipiti.--The Sipitis are described, in the Madras Census Report, 1901, as "Oriya temple priests and drummers; a sub-caste of Ravulo." In an account of them as given to me, they are stated to be Smartas, and temple priests of village deities, who wear the sacred thread, but do not employ Brahmans as purohits, and are regarded as somewhat lower in the social scale than the Ravulos. Some of their females are said to have been unrecognised prostitutes, but the custom is dying out. The caste title is Muni. (See Ravulo.) Sir.--A sub-division of Kanakkan. Sirpadam.--A sub-division of Kaikolan. Sirukudi.--A nadu or territorial division of Kallan. Siru Tali.--The name, indicating those who wear a small tali (marriage badge), of a sub-division of Kaikolan and Maravan. Sitikan.--Recorded, in the Travancore Census Report, 1901, as an occupational sub-division of Maran. Sitra.--See Pano. Siva Brahmana.--Recorded as a synonym of Stanika. Sivachara.--It is noted, in the Mysore Census Report, 1901, that the Lingayats call themselves "Vira Saivas, Sivabhaktas, or Sivachars. The Virasaiva religion consists of numerous castes. It is a religion consisting of representatives from almost every caste in Hindu society. People of all castes, from the highest to the lowest, have embraced the religion. There are Sivachar Brahmins, Sivachar Kshatriyas, Sivachar Vaisyas, Sivachar carpenters, Sivachar weavers, Sivachar goldsmiths, Sivachar potters, Sivachar washermen, and Sivachar barbers, and other low castes who have all followed the popular religion in large numbers."
