The Bi-Monthly Zoological Bulletin of the Division of Zoology of the Pennsylvania Department of Agriculture, Volume 3

The Bi-Monthly Zoological Bulletin was an official publication issued by the Division of Zoology within the Pennsylvania Department of Agriculture during the early 20th century. Volume 3, published around 1913, served as a primary vehicle for the state to disseminate research, pest control strategies, and general zoological information to farmers, educators, and the interested public. These bulletins were part of a broader push by state governments at the time to standardize agricultural practices through scientific documentation.

The publication reflected the era's utilitarian approach to natural history, focusing on the identification and management of insects, rodents, and other wildlife impacting regional crops. While the authors were professional staff members of the state department, the design and layout were typical of government periodicals of the period, favoring clear, instructional text accompanied by technical illustrations intended for practical utility rather than aesthetic appeal. It remains a significant primary source for historians studying the intersection of state-funded scientific inquiry and agricultural development in Pennsylvania.
