provided that he received 1,008 human heads. Seventy-one nādus sent the first-born sons for the sacrifice, but one nādu (Tirumarudhal) refused to send any. This refusal led to their isolation from the rest of the community. All the nādus are subject to the authority of four thisai nādus, and these in turn are controlled by the mahānādu at Conjeeveram, which is the residence of the patron deity Kamātchiamman. The thisai nādus are (1) Sīvapūram (Walajabad), east of Conjeeveram, where Kamātchiamman is said to have placed Nandi as a guard; (2) Thondipūram, where Thondi Vinayakar was stationed; (3) Virinjipūram to the west, guarded by Subramanya; (4) Sholingipūram to the south, watched over by Bairava. Each of the seventy-one nādus is sub-divided into kilai grāmams (branch villages), pērūr (big) and sithur (little) grāmams. In Tamil works relating to the Sengundar caste, Conjeeveram is said to be the mahānādu, and those belonging thereto are spoken of as the nineteen hundred, who are entitled to respect from other Kaikōlans. Another name for Kaikōlans of the mahānādu seems to be Āndavar; but in practice this name is confined to the headman of the mahānādu, and members of his family. They have the privilege of sitting at council meetings with their backs supported by pillows, and consequently bear the title Thindusarndān (resting on pillows). At present there are two sections of Kaikōlans at Conjeeveram, one living at Ayyampettai, and the other at Pillaipālayam. The former claim Ayyampettai as the mahānādu, and refuse to recognise Pillaipālayam, which is in the heart of Conjeeveram, as the mahānādu. Disputes arose, and recourse was had to the Vellore Court in 1904, where it was decided that Ayyampettai possesses no claim to be called the mahānādu.
