Easton's 1897 Bible Dictionary:

Island
   (Heb. 'i, "dry land," as opposed to water) occurs in its usual
   signification (Isa. 42:4, 10, 12, 15, comp. Jer. 47:4), but more
   frequently simply denotes a maritime region or sea-coast (Isa.
   20:6, R.V.," coastland;" 23:2, 6; Jer. 2:10; Ezek. 27:6, 7).
   (See CHITTIM.) The shores of the Mediterranean are
   called the "islands of the sea" (Isa. 11:11), or the "isles of
   the Gentiles" (Gen. 10:5), and sometimes simply "isles" (Ps.
   72:10); Ezek. 26:15, 18; 27:3, 35; Dan. 11:18).


Bouvier's Law Dictionary, Revised 6th Ed (1856):

ISLAND. A piece of land surrounded by water.
     2. Islands are in the sea or in rivers. Those in the sea are either in
the open sea, or within the boundary of some country.
     3. When new islands arise in the open sea, they belong to the first
occupant: but when they are newly formed so near the shore as to be within
the boundary of some state, they belong to that state.
     4. Islands which arise in rivets when in the middle of the stream,
belong in equal parts to the riparian proprietors when they arise. mostly on
one side, they will belong to the riparian owners up to the middle of the
stream. Bract. lib. 2, c. 2; Fleta, lib. 3, c. 2, s. 6; 2 Bl. 261; 1 Swift's

Code, art. 505, 507.
     5. The doctrine of the common law on this subject, founded on reason,
seems to have been borrowed from the civil law. Vide Inst. 2, 1, 22; Dig.
