The Mudbury War Memorial

The inhabitants of Mudbury recently erected a war memorial,

and they proposed to enclose a piece of ground on which it stands with posts.

They found that if they set up the posts $1$ foot asunder they would have too few by $150$.

But if they placed them a yard asunder there would be too many by $70$.

How many posts had they in hand?
