What was Silas's great accomplishment?
In Robert Frost's poem The Death Of The Hired Hand, Silas' great accomplishment is making hay bales. He gathers the dried grass together, 'bundles every forkful in its place,' and then 'tags and numbers it for future reference.' Silas is meticulously careful so that the process of unloading the bales from storage and using the hay as fodder is as seamless as possible. (Please refer to the link for examples of further uses of hay bales).
It seems apparent that Silas is especially proud of his practical skills. He feels that his former co-worker, Harold Wilson, might have benefited from some of Silas' practical, real world skills. Mary tells Warren that some of Harold's 'young college boy's assurance piqued him (Silas).' Silas thinks that if he could have taught Harold how to hay properly, ' he’d be/ Some good perhaps to someone in the world./ He hates to see a boy the fool of books.'
