MRS. B. desired Dr. Johnson to give his opinion of a new work she had
just written; adding, that if it would not do, she begged him to tell
her, for she had other _irons in the fire_, and in case of its not being
likely to succeed, she could bring out something else. "Then," said the
Doctor, after having turned over a few leaves, "_I advise you, Madam, to
put it where your other irons are._"
