From Jacob Biggle’s fabulously named Biggle Sheep Book: Something Practical About Sheep (All Wool and a Yard Wide Mutton Chops Cooked to Suit the Taste of the Most Fastidious)
There are a few more words of advice towards the bottom of the cover page, too:
"There is no use in keeping sheep if you have no time to bother with them."
