The Indians offered the first of the birds as an oblation to the Great Spirit, as a grateful acknowledgment of his bounty in having allowed them to gather food thus plentifully for their families; sometimes distant tribes with whom they were on terms of friendship were invited to share the sport and partake of the spoils. Indiana could not understand why Hector did not follow the custom of her Indian fathers, and offer the first duck or the best fish to propitiate the Great Spirit.
