A leg of mutton of six pounds will take an hour at a quick fire; if frosty weather an hour and a quarter; nine pounds an hour and a half; a leg of twelve pounds will take two hours: if frosty two hours and a half; a large saddle of mutton will take an hour and a half; and so on according to the size; a breast will take half an hour at a quick fire; a neck, if large, an hour; if very small, little better than half an hour, a shoulder much about the same time as a leg.
