But, on the whole, the oyster shellhas proved to be the best of available collectors on the At-lantic coast. There are some shells that are superior to it in manyrespects. Such are the thin, brittle shells of the scallop,the mussel, and the small jingle shells found on somebeaches. If these are used where currents are not strongenough to bear them away, oysters that grow on themwill break them into bits as soon as pressure is developedfrom crowding. In quiet waters these shells are idealcollectors because of this fact that the clusters formedon them will separate automatically without handling; but.
