OBS. 11.—­On Rules 7th and 8th, concerning Two Capitals for Compounds, I would observe, with a general reference to those compound terms which designate particular places or things, that it is often no easy matter to determine, either from custom or from analogy, whether such common words as may happen to be embraced in them, are to be accounted parts of compound proper names and written with capitals, or to be regarded as appellatives, requiring small letters according to Rule 9th.  Again the question may be, whether they ought not to be joined to the foregoing word, according to Rule 6th.  Let the numerous examples under these four rules be duly considered:  for usage, in respect to each of them, is diverse; so much so, that we not unfrequently find it contradictory, in the very same page, paragraph, or even sentence.  Perhaps we may reach some principles of uniformity and consistency, by observing the several different kinds of phrases thus used. 1.  We often add an adjective to an old proper name to make a new one, or to serve the purpose of distinction:  as, Now York, New Orleans, New England, New Bedford; North America, South America; Upper Canada, Lower Canada; Great Pedee, Little Pedee; East Cambridge, West Cambridge; Troy, West Troy.  All names of this class require two capitals:  except a few which are joined together; as Northampton, which is sometimes more analogically written North Hampton. 2.  We often use the possessive case with some common noun after it; as, Behring’s Straits, Baffin’s Bay, Cook’s Inlet, Van Diemen’s Land, Martha’s Vineyard, Sacket’s Harbour, Glenn’s Falls.  Names of this class generally have more than one capital; and perhaps all of them should be written so, except such as coalesce; as, Gravesend, Moorestown, the Crowsnest. 3.  We sometimes use two common nouns with of between them; as, the Cape of Good Hope, the Isle of Man, the Isles of Shoals, the Lake of the Woods, the Mountains of the Moon.  Such nouns are usually written with more than one capital.  I would therefore write “the Mount of Olives” in this manner, though it is not commonly found so in the Bible. 4.  We often use an adjective and a common noun; as, the Yellow sea, the Indian ocean, the White hills, Crooked lake, the Red river; or, with two capitals, the Yellow Sea, the Indian Ocean, the White Hills, Crooked Lake, the Red River.  In this class of names the adjective is the distinctive word, and always has a capital; respecting the other term, usage is divided, but seems rather to favour two capitals. 5.  We frequently put an appellative, or common noun, before or after a proper name; as, New York city, Washington street, Plymouth county, Greenwich village.  “The Carondelet canal extends from the city of New Orleans to the bayou St. John, connecting lake Pontchartrain with the Mississippi river.”—­Balbi’s Geog. This is apposition.  In phrases of this kind, the common noun often has a capital, but it seldom absolutely requires it; and in general a small
