The Dog (seaman)

Seaman was purchased by Lewis for $20 while he was in Pittsburgh. Seaman survived the trip and then continued on with his life with Meriwether Lewis.

On May 19, Lewis notes that Seaman was seriously hurt. One of the men had shot and wounded a beaver, and when Seaman went out to retrieve it, the animal bit him through the hind leg, cutting an artery. Both Lewis and Clark took extraordinary medical measures to save Seaman, and fortunately, the dog pulled through.

The Corps of Discovery carried one of the largest arsenals ever taken west of the Mississippi. It included an assortment of pikes, tomahawks and knives as well as several rifles and muskets, 200 pounds of gunpowder and over 400 pounds of lead for bullets.

Lewis also had a state-of-the-art pneumatic rifle he used to impress Indian tribes on the frontier. After pumping compressed air into the gun’s stock, he could fire some 20 shots—each of them almost completely silent.

While the stay at Fort Clatsop was peaceful, it was not entirely pleasant. The Clatsop Indian tribe was friendly, but Clark noted that the Indians were hard bargainers, which caused the expedition party to rapidly deplete its supply of gifts and trading goods, and eventually caused some resentment on both sides. © 2016, A&E Television Networks, LLC.

Among the Plains tribes Lewis and Clark met were the Osage, Sioux, Cheyenne, Crow, and Mandan. Upon reaching the Rocky Mountains, Lewis and Clark entered the country of the Plateau Indians. Living here were the Blackfeet, Flathead, Shoshone, Nez Perce, Spokane, and Yakima Indians.

Most vexing, though, was the damp coastal weather–rain fell all but twelve days of the expedition’s three-month stay. The men found it impossible to keep dry, and their damp furs and hides rotted and became infested with vermin. Nearly everyone suffered from persistent colds

Shoshone tribe

The bilingual Shoshone woman Sacagawea accompanied the Lewis and Clark Corps of Discovery expedition in 1805-06 from the northern plains through the Rocky Mountains to the Pacific Ocean and back. Her skills as a translator were invaluable, as was her intimate knowledge of some difficult terrain.

The Corps were still recovering from their portage around the Great Falls of Missouri. Morale was low. Lewis and three men were scouting ahead when they finally met a band of Shoshone. They were the first white men the Shoshone had ever seen.

In August 1805 Lewis and Clark were looking for the Shoshone Indians. The Corps (Lewis and Clark's expedition party) needed horses to cross the Rockies and the Shoshone had them. Sacagawea, a member of the Corps, was Shoshone, but she had been kidnapped by another tribe many years before.
