yielder

Out of the whole ninety-five [cows] there were eight in particular […] who, though the teats of one or two were as hard as carrots, gave down to her with a readiness that made her work on them a mere touch of the fingers. Knowing, however, the dairyman’s wish, she endeavoured conscientiously to take the animals just as they came, excepting the very hard yielders which she could not yet manage.

Their sense thus weak, lost with their fears thus strong,

Made senseless things begin to do them wrong;

For briers and thorns at their apparel snatch;

Some sleeves, some hats, from yielders all things catch.
