Things are typically mixed and moved along a canal using a combination of boats and barges, which transport goods and materials. Canals often feature locks to manage water levels and facilitate the movement of vessels. Cargo may be loaded and unloaded at docks along the canal, where cranes or other machinery assist in transferring items. Additionally, the natural flow of water can help in the transportation process, though the movement is primarily reliant on human-operated vessels.
Peristalsis. Food is actively moved (down) to the stomach.
The involuntary motion that moves food through the alimentary canal is called peristalsis and is a wavelike contraction and relaxation of the intestinal wall smooth muscles. It pushes food along the intestine.

Transportation
Shipping prices were cut and towns and cities sprung up along the canal making the area more populated. New York became very prosperous and overtook Philadelphia as the largest port. Immigrants came into New York and moved to the Midwest.
All goods were shipped, as well as people! Raw materials such as timber were moved east while pioneers with their families were moved west. Much of Michigan and Northern Ohio were settled by people traveling west on the Erie Canal.
Boats moved up and down in the Erie Canal using a system of locks. These locks are essentially water-filled chambers that can be raised or lowered. When a boat enters a lock, water is either added or drained to adjust the water level, allowing the boat to ascend or descend to the next segment of the canal. This innovative engineering enabled navigation across varying elevations along the canal's route.

To my knowledge no 'tribe' moved to Spain. There were many decedents of settlers who moved back to Europe, and were of mixed native blood but no actual "Tribe" moved.
Transportation. Prior to railroads. goods and passengers moved by canal boat.
