What did the animals of the Lewis and Clark expedition actually see?
Four animals knew the same continent in four completely different ways. Seaman the Newfoundland walked west with the Corps of Discovery. A prairie dog was caught and shipped east to President Jefferson, watching the whole country go by through the slats of a cage. A Nez Perce horse carried the strangers over mountains her people had always known. And a Pacific sea otter was already home when the expedition finally arrived. In this episode of Talking With Pets, they compare notes, and none of their knowledge overlaps.
History remembers the famous. Their pets remember the person. On Talking With Pets, a brown tabby cat named Prince MoRee contacts the animals of history and lets them tell what they really saw. This is the Witnesses format: several animals, one event, and the discovery that the same journey was many journeys depending on where you stood. True, surprising, and great for curious kids and the grown-ups listening with them.

From the episode
The sea otter: They stood at the water's edge and looked at me, and I looked at them, and they had traveled eight thousand miles to get to a place I had never left.
Roxie: (slowly) You each know a completely different piece of the continent.
Seaman: Yes.
Sacre: The cage piece. I know the cage piece.
What's true, what we filled in, what we imagined
Every episode of Talking With Pets is built in three honest layers. Here is how this one breaks down.
Documented in the historical record
The Corps of Discovery, authorized by Jefferson after the Louisiana Purchase, ran about 8,000 miles over 28 months with 33 members, from St. Louis in May 1804 to the Pacific in November 1805 and back by September 1806. Seaman the Newfoundland is named at least nineteen times in the journals, swimming, catching game, and chasing bears. The first winter was spent with the Mandan nation. In September 1805 the Nez Perce provided horses and guidance for the eleven-day Bitterroot crossing, without which the expedition would likely not have survived it. A prairie dog caught in autumn 1804 was shipped east the next spring and arrived alive in Washington for Jefferson's study. Lewis documented the marine animals of the Pacific coast, and Lewis and Clark made the first detailed maps of the American Northwest.
Grounded inference from the record
The Nez Perce horse and the sea otter are composites built on documented facts: the Nez Perce horses and knowledge that carried the Corps over the mountains, and the sea otters Lewis recorded at the coast. The prairie dog is a documented animal with an invented name and an inferred experience of the cage and the journey east. Accounts of Seaman refusing to leave Lewis's grave after his death in 1809 exist but cannot be fully verified, so the episode treats them as probable rather than certain.
Story, voice, and feeling
The séance and the four-voice conversation are imagined. The episode's idea is real, though: you can be exploring something that other people already know. The mountains were not a mystery to the Nez Perce, and the Pacific was already home to the sea otter when the Corps arrived. Four animals know the same continent, and none of their knowledge overlaps.

What was the Lewis and Clark expedition?
The Corps of Discovery was authorized by President Jefferson after the Louisiana Purchase. Thirty-three members left St. Louis in May 1804, reached the Pacific near present-day Astoria, Oregon in November 1805, and returned in September 1806, about 8,000 miles in 28 months. They made the first detailed maps of the American Northwest. Source: National Park Service; the expedition journals.
Did a prairie dog really get mailed to President Jefferson?
Yes. The Corps caught a prairie dog in autumn 1804 in present-day Nebraska, held it through the winter, and shipped it east the following spring. It arrived alive in Washington, along with a magpie, for Jefferson's scientific study. Source: the expedition journals.
How did the expedition survive the Bitterroot Mountains?
With help. In September 1805 the Nez Perce nation provided horses and guidance for the eleven-day Bitterroot crossing, the hardest stretch of the whole journey, during which the Corps ran out of food. Without that assistance the expedition would likely not have survived the crossing. The mountains were not a mystery to everyone. Source: National Park Service, Nez Perce National Historical Park.
Is this the same Seaman from the other Talking With Pets episode?
Yes. Seaman, Lewis's Newfoundland, has his own Talking With Pets episode telling the whole walk in his own voice. In this Witnesses episode he sits on a panel with three animals who knew the same continent in completely different ways, which is the point of the format.
What is Talking With Pets, and is it good for kids?
Talking With Pets is an educational history podcast for curious kids ages 6 to 10 and the grown-ups listening with them. A brown tabby cat named Prince MoRee contacts the pets of history's greatest figures, who tell the true story of the person they knew. Every episode is sourced and divided into what is documented, what was filled in, and what was imagined, which makes it a quiet lesson in how to weigh sources. It is a Talking With Pets production.
