Many moons ago, I used the Calvert curriculum for something like 3rd-8th grade. I remember reading a poem about two brothers who had very different philosophies about how to accomplish their goals; each ended up ruining the other's work. I believe the last stanza went like this:
Across the sea, the wide, wide sea
Two brothers are breaking their hearts.
I feel like there was another line where one brother laments
"My blood, my sweat, my tears."
Does anybody remember the poem? I have not been able to find it online.
