When I was in Grade Five, I think, or perhaps Grade Six, at my grade school in Canada, we read a poem in our reader which ignited my fascination for far places. I remember not a lot of it, except that it included exotic words like Zanzibar and Samarkand, and it fired little imaginations, like mine. About the spice trade, maybe? For some reason, I always thought it to be a poem by Robert Louis Stephenson, but all my searches would indicate otherwise.It's not the Scotsman one, definitely.
Might you be speaking of Bliss Carmans' "The Ships of Yule"? A Canadian myself, I know that he was very popular in the text books of the late 40's to the early 60's.
Oh, yes! I searched and found the poem, and yes, that is it indeed! Thank you so much!
