Priscilla, idly turning the pages of the “Gerard” which Ellinor had left out of her hand on the sundial, stood silent, shooting glances by turns at Harcourt and Herrick. The former, standing with folded arms behind Ellinor, the latter, lying stretched on the hot soil at her feet, seemed too thoroughly content with their posts to be lured from them. But at Ellinor’s exclamation, the little circle had been stirred.

“Poison?” echoed Master Simon in his turn. “Tush! Ellinor, I am ashamed of you! By this time you should know better. Is not every medicine, nay, every distilled spirit, poison in certain degrees?
