Riddle 119

Eagerly I my first the pack
So that we might pursue the game;
I made a good deal, but the lack
Of interest made the sport seem tame.

My second ladies richly gowned
May see in patterns of their silk,
My second also may be found
In terrapin and buttermilk.

My whole will fly right merrily
O’er many a cold and chilly mile;
’T is only one, yet verily
’T would equally describe a file.
