Easton's 1897 Bible Dictionary:

Cottage
   (1.) A booth in a vineyard (Isa. 1:8); a temporary shed covered
   with leaves or straw to shelter the watchman that kept the
   garden. These were slight fabrics, and were removed when no
   longer needed, or were left to be blown down in winter (Job
   27:18).

     (2.) A lodging-place (rendered "lodge" in Isa. 1:8); a
   slighter structure than the "booth," as the cucumber patch is
   more temporary than a vineyard (Isa. 24:20). It denotes a frail
   structure of boughs supported on a few poles, which is still in
   use in the East, or a hammock suspended between trees, in which
   the watchman was accustomed to sleep during summer.

     (3.) In Zeph. 2:6 it is the rendering of the Hebrew _keroth_,
   which some suppose to denote rather "pits" (R.V. marg., "caves")
   or "wells of water," such as shepherds would sink.
