"The reply attributed to the barbarian," added Ischomachus, "appears to me to be exceedingly to the purpose, for when the King of Persia having met with a fine horse and wishing to have it fattened as soon as possible, asked one of those who were considered knowing about horses what would fatten a horse soonest, it is said that he answered 'the master's eye.'"] [Footnote 21: The English word "orchard" scarcely translates _arbustum_, but every one who has been in Italy will recall the endless procession of small fields of maize and rye and alfalfa through which serried ranks of mulberry or feathery elm trees, linked with the charming drop and garland of the vines, seem to dance toward one in the brilliant sunlight, like so many Greek maidens on a frieze. These are _arbusta_.] [Footnote 22: Cato was a strong advocate of the cabbage; he called it the best of the vegetables and urged that it be planted in every garden for health and happiness. Horace records (Odes. III, 21, 11) that old Cato's virtue was frequently warmed with wine, and Cato himself explains (CLVI) how this could be accomplished without loss of dignity, for, he says, if, after you have dined well, you will eat five cabbage leaves they will make you feel as if you had had nothing to drink, so that you can drink as much more as you wish--"bibesque quantum voles!" This was an ancient Egyptian precaution which the Greeks had learned. Cf. Athenaeus, I, 62.] [Footnote 23: Henry Home, Lord Kames, a Scots judge of the eighteenth century, whom Dr. Johnson considered a better farmer than judge and a better judge than scholar, but who had many of the characteristics of our _priscus_ Cato, argues (following an English tradition which had previously been voiced by Walter of Henley and Sir Anthony Fitzherbert) in his ingenious _Gentleman Farmer_ against the expense of ploughing with horses and urges a return to oxen. He points out that horses involve a large original investment, are worn out in farm work, and after their prime steadily depreciate in value; while, on the other hand, the ox can be fattened for market when his usefulness as a draught animal is over, and then sell for more than his original cost; that he is less subject to infirmities than the horse; can be fed per tractive unit more economically and gives more valuable manure. These are strong arguments where the cost of human labour is small and economical farm management does not require that the time of the ploughman shall be limited if the unit cost of ploughing is to be reasonable. The ox is slow, but in slave times he might reasonably have been preferred to the horse. Today Lord Kames, (or even old Hesiod, who urged that a ploughman of forty year and a yoke of eight year steers be employed because they turned a more deliberate and so a better furrow) would be considering the economical practicability of the gasolene motor as tractive power for a gang of "crooked" ploughs.]
