Does any1 know who wrote this or the rest of the words

Away
I cannot say, and I will not say
that he is dead-he is just away!
With a cheery smile and a wave of the hand,
He has wandered into an unknown land,
and left us dreaming how very fair
It needs must be, since he lingers there,
and you, O you, who the wildest yearn
for the old time step and the glad return,
think of him faring on, as dear
in the love of there as the ove of here:
think of him still as the same,
I say: he is not dead-he is just away.

~James Whitcomb Riley
