Seaman is a very intriguing book about a courageous and loyal dog named Seaman as he travels with Lewis and Clark and the Corps of Discovery on a historical adventure. The author, Gail Langer Karwoski, used Lewis's diary own in order to write this book. Based on the journal entries, Seaman played a huge role in the success of the expedition. While the author used actual notes from Lewis's diary, she also used her own imagination to make the story more realistic. The book includes vivid details about the thrilling things this dog does for his owners' safety and well being. At first, Seaman is hesitant to venture aboard a boat that would travel up the Mississippi River into utter wilderness, but a strong bond eventually develops between Lewis and his trusty companion. Every day spent traveling with Seaman on the boat was memorable, including successful hunts as well as the days Lewis spent ill. Seaman proved to be an amazing prey retriever. For example, only a few days into the trip, a large group of squirrels traversed the mighty river in front of the boat! Seaman immediately jumped into the water and caught as many squirrels as the men could eat! I found this part of the book very interesting because I never would have imagined that squirrels would attempt to cross a river, let alone in large quantities. The Corps of Discovery encountered many Native Americans during their voyage, and Seaman helped the Corps of Discovery appear more impressive than they felt. His enormous size and intimidating jaws kept the Indians from raiding camp. These characteristics also saved Lewis from a colossal grizzly bear with an immense appetite. When the Corps of Discovery was forced to cross the Rocky Mountains, Seaman helped keep everyone's spirits up, even when they were suffering from cold and hunger. After crossing the never-ending fang-white mountains, their destination of the Pacific Ocean was just around the corner. When the Corps of Discovery reached the expanse of turquoise salt water, Seaman officially lived up to his name. He was named Seaman because his master knew he would get to experience the unforgiving sea. No one knows what happened to Seaman after the Corps of Discovery returned from their adventure, but in the book, he continued to explore the West with a member of the expedition, John Colter. I will always remember this book and I recommend it to anyone who enjoys heroic dog stories.
