[Footnote 12: Every rural community in the Eastern part of the United States has grown familiar with the contrast between the intelligent amateur, who, while endeavoring earnestly to set an example of good agriculture, fails to make expenses out of his land, and the born farmer who is self-supporting in the practice of methods contemned by the agricultural colleges. Too often the conclusion is drawn that scientific agriculture will not pay; but Cato puts his finger on the true reason. The man who does not depend on his land for his living too often permits his farm to get what Cato calls the "spending habit." Pliny (_H.N._ XVIII, 7) makes some pertinent observations on the subject: "I may possibly appear guilty of some degree of rashness in making mention of a maxim of the ancients which will very probably be looked upon as quite incredible, 'that nothing is so disadvantageous as to cultivate land in the highest style of perfection.'" And he illustrates by the example of a Roman gentleman, who, like Arthur Young in eighteenth century England, wasted a large fortune in an attempt to bring his lands to perfect cultivation. "To cultivate land well is absolutely necessary," Pliny continues, "but to cultivate it in the very highest style is mere extravagance, unless, indeed, the work is done by the hands of a man's own family, his tenants, or those whom he is obliged to keep at any rate."] [Footnote 13: In this practice has been the delight of men of affairs of all ages who turn to agriculture for relaxation. Horace cites it with telling effect in the ode (III, 5) in which he describes the noble serenity of mind with which Regulus returned to the torture and certain death which awaited him at Carthage: and Homer makes an enduring picture of it in the person of the King supervising his fall ploughing, which Hephsestus wrought upon the shield of Achilles (_Iliad_, XVIII, 540). "Furthermore, he set in the shield a soft fresh ploughed field, rich tilth and wide, the third time ploughed, and many ploughers therein drove their yokes to and fro as they wheeled about. Whensoever they came to the boundary of the field and turned, then would a man come to each and give into his hands a goblet of sweet wine: while others would be turning back along the furrows, fain to reach the boundary of the deep tilth, ... and among them the King was standing in silence, with his staff, rejoicing in his heart."]
