Felling fellows is a term used to describe a group of axmen, or people who use axes to cut down trees. The term is derived from the act of felling, which is the process of cutting down trees. Axmen are typically employed in forestry and logging operations, where they use their axes to cut down trees for timber or other purposes. Felling fellows are an important part of the forestry industry, as they are responsible for the safe and efficient removal of trees.
