Vellalars as agriculturists 

I dispute the argument that Vellalars are basically agriculturists.  Even historian Mr. Vincent A Smith in his book 'The Oxford Student's History of India' says, Vellalars are one of the caste in Tamil Nadu which do not have any association with any one particular job.  Like every caste of Tamil Nadu including Mudhaliar, Udayar, Vanniar, Nadar, Gownder, Vellalars too involved in farming.  You can also refer the Gazette of Salem District publish by Tamil Nadu government.

Vellalars migrated to Kerala along with Pandiyan kings, as Pandians needed scholars with them when they had war with Cheras.

If no one replies to this dispute, I will re-write the contents about Vellalars's occupation
