Famous quotes containing the words sweat and/or test:
““Although I’d lie lapped up in linen
A deal I’d sweat and little earn
If I should live as live the neighbours,”

Nor could it ever have been old.
For he, to whom we had applied
Our shopman’s test of age and worth,
Was elemental when he died,
As he was ancient at his birth:”
