Where can I find a poem or similiar by R L Stevenson to S.R. Crockett?

Question

"After a few stanzas it contains the lines
So be my passing,
Let me be gathered to the quiet west,
my task accomplished and the long day done."

Answer 1

Blows the wind today,
and the sun and the rain are flying,
Blows the wind on the moors today and now,
Where about the graves of the martyrs the whaups are crying
My heart remembers Now!
