Loading the Keelboat at Pittsburgh

With the keelboat finally ready, Lewis supervised the loading of supplies and equipment. The cargo included 14 bales of Indian presents (beads, mirrors, ribbons, knives, and medals), weapons, ammunition, scientific instruments, medicines, and provisions.

The packing had to be done carefully to distribute weight evenly and keep essential items accessible. Lewis organized the cargo with military precision, drawing on his experience as an Army officer.
