"Arming" for hard clams is done in shallow water at low tide during the warm months, April through October.

Most "baymen" have learned by experience to wear protective clothing consisting of rubber gloves and three or four pairs of nylon stockings to cover both upper extremities from wrists to shoulders. If protective clothing is not worn, an eruption appears upon the immersed portion of their skins.
