Somebody said that it couldn't be done,
But he with a chuckle replied
"maybe it couldn't," but he would be one
wouldn't say so till he'd tried.
he buckled right in with the trace of a grin
his face. If he worried he hid it.
He started to sing as he tackled the thing
That couldn't be done, and he did it.

It Couldn't Be Done, stanza 1, The Path to Home, p. 38 (1919).
