`` Freckles , '' said the chief , `` wash the breakfast things ; put them in order ; take them all into the pantry . When you have done , go out by the back door , being careful to put on the old man 's disguise to-day . Fasten the wig firmly on , and put a patch over your eye . Here 's five shillings ; get food for the day , and be here by twelve o'clock sharp . Now go . '' `` Yus , sir . '' Freckles had an exceedingly cheerful manner .
