Walt Whitman - No Labor-Saving Machine

NO labor-saving machine,
Nor discovery have I made;
Nor will I be able to leave behind me any wealthy bequest to found a
hospital or library,
Nor reminiscence of any deed of courage, for America,
Nor literary success, nor intellect--nor book for the book-shelf;
Only a few carols, vibrating through the air, I leave,
For comrades and lovers.

Walt Whitman
