Trees of the Northern United States Their Study, Description and Determination

"Trees of the Northern United States" by A. C. Apgar is a scientific guide from the late 1800s designed to help people learn about and identify trees in the northern U.S. Aimed at students and teachers, the book focuses on building a strong understanding and appreciation for native and grown tree types by observing trees directly. The book begins with the author's goal of providing students with practical knowledge, and expressing the limitations of books that didn't focus on tree parts like leaves and bark that are easy to find and observe. Apgar pushes hand-on learning so users can better develop their observation skills, and expand their botanical vocabulary, allowing a structured way to learn about tree anatomy, it's classification, and how to identify it.
