[Footnote 17: The philosophy of Cato's plan, of laying out a farm is found in the agricultural history of the Romans down to the time of the Punic wars. Mommsen (II, 370) gives the facts, and Ferrero in his first volume makes brilliant use of them. There is sketched the old peasant aristocrat living on his few acres, his decay and the creation of comparatively large estates worked by slaves in charge of overseers, which followed the conquest of the Italian states about B.C. 300. This was the civilization in which Cato had been reared, but in his time another important change was taking place. The Roman frontier was again widened by the conquest of the Mediterranean basin: the acquisition of Sicily and Sardinia ended breadstuff farming as the staple on the Italian peninsular. The competition of the broad and fertile acres of those great Islands had the effect in Italy which the cultivation of the Dakota wheat lands had upon the grain farming of New York and Virginia. About 150 B.C. the vine and the olive became the staples of Italy and corn was superseded. Although this was not accomplished until after Cato's death, he foresaw it, and recommended that a farm be laid out accordingly, and his scheme of putting one's reliance upon the vine and the olive was doubtless very advanced doctrine, when it first found expression.] [Footnote 18: Pliny quotes Cato as advising to buy what others have built rather than build oneself, and thus, as he says, enjoy the fruits of another's folly. The _cacoethes aedificandi_ is a familiar disease among country gentlemen.] [Footnote 19: Columella (I,4) makes the acute observation that the country house should also be agreeable to the owner's wife if he wishes to get the full measure of enjoyment out of it. Mago, the Carthaginian, advised to, "if you buy a farm, sell your house in town, lest you be tempted to prefer the cultivation of the urban gods to those of the country."] [Footnote 20: According to German scholarship the accepted text of Cato's version of this immemorial epigram is a model of the brevity which is the test of wit, "Frons occipitio prior est." Pliny probably quoting from memory, expands it to "Frons domini plus prodest quam occípitíum." Palladius (I, 6) gives another version: "Praesentia domini provectus est agri." It is found in some form in almost every book on agriculture since Cato, until we reach the literature in which science has taken the place of wisdom--in the Byzantine _Geoponica_, the Italian _Crescenzi_, the Dutch _Heresbach_, the French _Maison Rustique_, and the English _Gervase Markkam. Poor Richard's Almanack_ gives it twice, as "the foot of a master is the best manure" and "the eye of a master will do more work than both his hands." It is perennial in its appeal. The present editor saw it recently in the German comic paper _Fliegende Blätter_. But the jest is much older than Cato. It appears in Aeschylus, _Persae_, 171 and Xenophon employs it in _Oeconomicus_ (XII, 20):
