When Nāttukōttai Chettis adopt children, they must belong to the same temple division. An adopted son is called Manjanir Puthiran, or turmeric-water son, because, at the ceremony of adoption, the lad has to drink turmeric-water.[42] In villages where their main temples are situated, the temple manager is obliged to give food to stranger Chettis, and charge for it if they belong to another temple division.

According to a variant of the story relating to the origin of the Nāttukōttai Chettis, “they were formerly merchants at the court of the Chōla kings who ruled at Kaveripattanam, at one time a flourishing sea-port at the mouth of the Cauveri, from which they emigrated in a body on being persecuted by one of them, and first settled at Nattarasankottai, about three miles north-east of Sivaganga.”

By other castes, the Nāttukōttai Chettis are said to be the descendants of the offspring of unions between a Shānān and a Muhammadan and Uppu Korava women. Some of the peculiarities of the caste are pointed out in support of the story. Thus, Nāttukōttai men shave their heads like Muhammadans, and both men and women have the lobes of their ears dilated like the older Shānāns. Their girls wear necklaces of shell beads like Korava women, and the women delight in making baskets for recreation, as the Korava women do for sale. The caste is sometimes spoken of as Uppu (salt) Maruhira Chetti. The arguments and illustrations are naturally much resented by the Nāttukōttai Chettis, who explain the obnoxious name by the story that they were formerly very poor, and made a living by selling salt.

The Nāttukōttai Chettis have recourse to panchāyats (councils) in matters affecting the community. They have, Mr. Sundara Aiyar writes, “been at any rate till recently remarkable for settling their differences out of court. The influence of the elders in preventing litigation is very strong. They conciliate the disputants as far as possible and, after reducing the difference between them to a minimum, they often get their signatures to an award, in which a blank is left to decide the still existing point of difference, the disputants agreeing, after putting in their signatures, to the mediators’ filling in the blank, and deciding the dispute as they choose. We are afraid that this spirit of give-and-take is now unfortunately diminishing, and the arbitrament of the courts is more often resorted to than before.” There are, among the Nāttukōttai Chettis, two forms of panchāyat, called madaththuvāsal mariyal (matam panchāyat) and kōvilvāsal mariyal (temple panchāyat), of which, at the present day, only the latter is in vogue. For every temple there is a manager, an assistant, and a servant called Vairāvi, who must be a Melakkāran. The aggrieved party lodges his complaint with the manager, who sends word to the leading men of the temple division concerned. The complainant and defendant are summoned to attend a council meeting, and the evidence is recorded by the temple manager. If the accused falls to put in an appearance, the Vairāvi is sent to his house, to take therefrom adavu (security) in the shape of some article belonging to him. In a recent case, a wealthy Nāttukōttai Chetti promised his brother’s widow that she should be allowed to adopt a boy. But, as the promise was not fulfilled, she complained to the temple; and, as her brother-in-law did not attend the council meeting, the Vairāvi went to his house, and, in his absence, abstracted the adavu. This was regarded as a great insult, and there was some talk of the case going into court. Matters such as the arrangement of marriage contracts, monetary disputes, family discussions, and the like, are referred to the temple council for settlement. Final decisions are never recorded in writing, but delivered by word of mouth. Those who fail to abide by the decision of the council do not receive a garland from the temple for their marriage, and without this garland a marriage cannot take place.

It is noted by Mr. Hayavadana Rao that each of the kōvils or temples “is managed by Karyakārans, who are nominated to the place by the local elders. These Karyakārans act as Panchāyatdars, and decide all civil cases referred to them. If a case is first referred to them, it may, if necessary, be carried over again to the established courts of the country. But, if once a case is first taken to the courts, they would not entertain it before themselves. They enforce their decrees (1) by refusing to give the garland of flowers at the marriage time, (2) by exercising the power of excommunication.”

Every Nāttukōttai Chetti youth has to perform a ceremony called Sūppidi before marriage. On the Karthika day, when the constellation Krithikai is in the ascendant, he is taken on horseback to a Pillayar (Ganēsa) temple, where he worships, and whirls a bag of burning charcoal tied to a long string round his head. In front of the temple he burns a booth (chokkapane), which has been set up, and with the ashes his forehead is marked. On his return home, and at the entrance of Nāttukōttai houses which he passes, rice lamps are waved before him (alathi). In like manner, every girl has to go through a ceremony, called thiruvādhirai, before marriage. On the day of the Arudrādarsanam festival, she is bathed and decorated. A necklace of gold beads is placed on her neck instead of the necklace of glass beads (pāsimani), which she has hitherto worn. She proceeds, with a silver cup, to the houses where other girls are performing the ceremony, and bawls out:—

I have come dancing; give me avarakkai (Dolichos Lablab beans).

I have come singing; give me padavarangkai (Cyamopsis beans).

I have come speaking; give me sorakkai (Lagenaria fruit).

Various kinds of vegetables are placed on the silver vessel, cooked, and distributed. Cakes, called dosai, are made in the house, and, during their preparation, holes are made in them by married women with an iron style. These cakes are also distributed, and it is taken as an insult if any individual does not receive one.
