G. A.R.--query

[Gerald Cohen]

   Would anyone have any idea what "G.A.R." stands for in the quote
below. It appears in the newspaper _San Francisco Bulletin_,April 19,
1913, p.13/5; "Sporting Tit-Bits by  'Mac'" and concerns pitching
great Cy Young:
   "Isn't it appropriate for 'Cy' Young to become a manager in the
Federal League?  Cy is a member of the G. A.R. so far as the baseball
fans are concerned."

   That's is the entire item.
