DRUM-MAJOR is not only the first drummer in the regiment, but has the same authority over his drummers as the corporal has over his squad. He instructs them in their different beats, and is daily at orders with the sergeants, to know the number of drummers for duty. He marches at their head when they beat in a body; and in the day of battle, or at exercise, he must be very attentive to the orders given him, that he may regulate his beats according to the movements ordered.
