Grandfer's Wonderful Garden by Eleanora H. Stooke

FOR several days Billy was ill, so ill that he kept his bed, and the doctor who attended him insisted he should have a night nurse. Accordingly Mrs. Varcoe was engaged to fill that position.

"Such an expense! " Billy overheard Mrs. Brown grumbling to her daughter, who came to Rowley Cottage, greatly concerned, as soon as she heard of his illness. "The doctor says he's still suffering from shock to some extent, and his nerves are unstrung. I never bargained he would be as delicate as this."
