* Field is often used adjectively in the sense of belonging to, or used in, the fields; especially with reference to the operations and equipments of an army during a campaign away from permanent camps and fortifications. In most cases such use of the word is sufficiently clear; as, field battery; field fortification; field gun; field hospital, etc. A field geologist, naturalist, etc., is one who makes investigations or collections out of doors. A survey uses a field book for recording field notes, i.e., measurment, observations, etc., made in field work (outdoor operations). A farmer or planter employs field hands, and may use a field roller or a field derrick. Field sports are hunting, fishing, athletic games, etc.
