In this publication, Dice and Sherman present the findings from their extensive fieldwork conducted during the summer of 1920, where they cataloged various mammal species across diverse habitats, including woodlands, wetlands, and meadows. The authors meticulously describe the ecological conditions, the identification of mammals observed, and the varying habitats where these species were found. Through an annotated list, they provide insights into the distribution and relative abundance of mammals, including species such as the black bear, porcupine, and various shrew types, as well as the environmental conditions influencing these populations. Overall, the book serves as both a detailed ecological study and a historical snapshot of the mammal fauna in northwestern Michigan.
