It was a paradise for the Thug.
When the autumn opened, the Thugs began to gather together by pre-concert.

Other people had to have interpreters at every turn, but not the Thugs; they could talk together, no matter how far apart they were born, for they had a language of their own, and they had secret signs by which they knew each other for Thugs; and they were always friends.

Even their diversities of religion and caste were sunk in devotion to their calling, and the Moslem and the high-caste and low-caste Hindoo were staunch and affectionate brothers in Thuggery.
When a gang had been assembled, they had religious worship, and waited for an omen.

They had definite notions about the omens.

The cries of certain animals were good omens, the cries of certain other creatures were bad omens.
