"croaker sacks" were burlap bags / sacks used to hold frogs when caught. The burlap bags / sacks enabled the frogs to stay alive and damp while other "croakers" were captured (called frog gigging). According to an article I copied years ago, the central Florida county of Hardee was called "the frog leg capital of the world" during a part of the 1930's, because so many frogs were shipped from that area to France. I will try to locate the copy of the article for verification of the last sentence
The boys struggled to carry the heavy burlap sacks to the trucks. The sacks were called croaker sacks, because inside the sacks were dozens of frogs, each one croaking loudly.
