"The Hindoo portion of the community occupies, in Sindh, the same social position that the Mussulmans do in India. As in Arabia, Affghanistan and other parts of Central Asia, the Hindoo here is either employed in trade, or in ministering to the religious wants of his caste-brethren. We, therefore, find among them none of the properly speaking outcast tribes (as Parwari, Mang, Chandala and others) so numerous in their own country. It is probable that few or none of the Hindoo families that flourished in Sindh at the time of the first Moslem inroad have survived the persecution to which they were then subjected: most likely they either emigrated or were converted to Islam. The present race is of Punjabi origin, as their features and manners, ceremonies and religious opinions, as well as their names, sufficiently prove. It may be observed that they show a general tendency towards the faith of Nanak Shah, and that many castes have so intermingled the religion of the Sikh with their original Hinduism, that we can scarcely discern the line of demarcation. As usual among the Hindoo race, wherever it is settled, they have divided themselves into different tribes. The Satawarna, or seven castes of Indians, in Sindh, are as follows:- 1. Brahman; 2. Lohano; 3. Bhatio; 4. Sahto; 5. Waishya (including a number of trades as Wahun, grain-toaster; Khatti, dyer, &c.); 6. Punjabi; and 7. Sonaro. Five of these belong, properly speaking, to the Waishya (the third, or merchant) division of pure Indians. The seventh is a mixed caste, descended from a Brahman father and a Shudra mother. In Sindh he is usually considered as belonging to the servile tribe. Of the first, or Brahminical class, we find two great bodies, which are divided and subdivided as usual. These are – 1. Pokarno; 2. Sarsat or Sarsudh."
