Roget classifies it as a list of containers, in close proximity to such things as "nosebag"and"swag" as giving some indication of its meaning.
I perpetually see horses standing with their nosebags on, though they are not feeding.
I saw the man stop the cart, put on the horse's nosebag and chain up the wheel.
The military leaders are warhorses, in the sense that they have nosebags filled with paper put about their necks every morning.
