In the second class of cases, where we have different names for the same place, we may cite Bangs Island, at the entrance to Portland harbor; an effort was made not long ago to change this name on the Coast Survey charts to Cushing's Island, the evidence was so strong that an order was issued to effect the change, when the supporters of "Bangs" produced additional evidence and secured the retention of that name. On the coast of Florida we had two Saint Joseph's Bays, and a comparatively modern name, "Anclote Anchorage," was presented to take the place of a part of one of them, which led to designating the rest of the bay "Saint Joseph's Sound," Sound being more appropriate for the locality. We have also some notable instances on the Pacific coast, as "Cape Orford" or "Blanco;" "Cape Gregory" or "Arago;" "South Farallon" or "Southeast Farallon;" and in Alaska there are instances too numerous to mention. In the third class of cases, the locality to which the name applies, we may cite "Isle-au-Haut" Bay and "East Penobscot" Bay, on the coast of Maine; "Hempstead" Bay, on the coast of Long Island, a bay which is almost filled with small islands, rendering it most difficult to satisfactorily define the limits; "Chincoteague" Bay, on the Jersey coast, is an instance of growth; it was at one time called "Assateague," and although "Assateague" was retained for many years as applicable to the upper part of the bay, it has finally been restricted to a very small cove in Assateague Island. On the Pacific coast there are a great many instances, possibly one of the most difficult relates to the limits of Admiralty Inlet, how far it extends into Puget sound? Again, to the northward, is what for years has been called "Washington" Sound, an effort is being made to change it to "Possession" Sound, the latter name, I believe, was once applied to a portion of the area; perhaps we shall eventually see both names on the chart. The difficulty of defining the limits to which a name applies may be experienced in dealing with "Hampton Roads," or "Tybee Roads;" apparently simple problems, but who will undertake to define the exact limits of these famous roadsteads?
