Bull boat

A bull boat is a type of boat made from animal hides that were sewn together. The animal hide was usually from a buffalo, which is why it's also called a buffalo boat.

To make a bull boat, you first need to find a large animal hide from a buffalo. You then need to sew the edges of the hide together to make a circle that is watertight.

Next, you need to fill the boat with air so that it floats. This is usually done by blowing into the boat's mouth, which is left open.

Once the boat is inflated, you can use it to float down a river or cross a body of water. The bull boat was commonly used by Native American tribes, who would use it to hunt and travel.

Overall, a bull boat is a simple yet effective way to cross a river or body of water using an animal hide that has been turned into a boat.
