And seeing they were so wounded that there was no hope of curing them, their comrades stripped them, and put them still living inside the gabions, which served to fill them up.

  Quotations
  The meaning of the word Gabion, as it is used in the poem, is not to be sought for in any dictionary. It was of the venerable old gentleman Mr Ruthven′s own coining, and it was well enough understood among his select friends, to mean nothing else but the miscellaneous curiosities in his closet humorously described in the poem.
