Glengarry Cap. [So named from Glengarry, a valley in Scotland]. A Scotch cap of wool, either woven in one piece or cut out of cloth and sewed together. It has erect sides, a hollow or crease at the top, and diminishes in height toward the back, where the band is slit or parted and fitted with a pair of short ribbons, which are usually crossed and permitted to hang down. It is the typical cap of the Scotch Highlander.
