Our author divides the _Villaticæ pastiones_ into poultry, game, and fish. Under the first class, he comprehends birds, such as thrushes, which are kept in aviaries, to be eaten, but not any birds of game. Rules and directions are given for their management, of the same sort with those concerning the animals mentioned in the preceding book. The aviaries in the Roman villas were wonderfully productive and profitable. A very particular account is given of the construction of an aviary. Varro himself had one at his farm, near Casinum, but it was intended more for pleasure and recreation than profit. The description he gives of it is very minute, but not very distinct. The pigeon-house is treated of separately from the aviary. As to the game, the instructions do not relate to field-sports, but to the mode of keeping wild animals in enclosures or warrens. In the more simple and moderate ages of the republic, these were merely hare or rabbit warrens of no great extent; but as wealth and luxury increased, they were enlarged to the size of 40 or 50 acres, and frequently contained within their limits goats, wild boars, and deer. The author even descends to instructions with regard to keeping and fattening snails and dormice. On the subject of fish he is extremely brief, because that was rather an article of expensive luxury than homely fare; and the candidate, besides, was now momentarily expected. Fish-ponds had increased in the same proportion as warrens, and in the age of Varro were often formed at vast expense. Instances are given of the great depth and extent of ponds belonging to the principal citizens, some of which had subterraneous communications with the sea, and others were supplied by rivers, which had been turned from their course. At this part of the dialogue, a shout and unusual bustle announced the success of the candidate whom Varro favoured: on hearing this tumult, the party gave up their agricultural disquisitions, and accompanied him in triumph to the Capitol.
This work of Varro is totally different from that of Cato on the same subject, formerly mentioned. It is not a journal, but a book; and instead of the loose and unconnected manner in which the brief precepts of the Censor are delivered, it is composed on a plan not merely regular, but perhaps somewhat too stiff and formal. Its exact and methodical arrangement has particularly attracted the notice of Scaliger.--"Unicum Varronem inter Latinos habemus, libris tribus de Re Rustica, qui vere ac { ~GREEK SMALL LETTER MU~}{ ~GREEK SMALL LETTER EPSILON~}{ ~GREEK SMALL LETTER THETA~}{ ~GREEK SMALL LETTER OMICRON~}{ ~GREEK SMALL LETTER DELTA~}{ ~GREEK SMALL LETTER IOTA~}{ ~GREEK SMALL LETTER KAPPA~}{ ~GREEK SMALL LETTER OMEGA~}{ ~GREEK SMALL LETTER FINAL SIGMA~} philosophatus sit. Immo nullus est Græcorum qui tam bene, inter eos saltem qui ad nos pervenerunt(61)." Instead, too, of that directness and simplicity which never deviate from the plainest precepts of agriculture, the work of Varro is embellished and illustrated by much of the erudition which might be expected from the learning of its author, and of one acquainted with fifty Greek writers who had treated of the subject before him. "Cato, the famous Censor," says Martyne, "writes like an ancient country gentleman of much experience: He abounds in short pithy sentences, intersperses his book with moral precepts, and was esteemed a sort of oracle. Varro writes more like a scholar than a man of much practice: He is fond of research into antiquity, and inquires into the etymology of the names of persons and things. Cato, too, speaks of a country life, and of farming, merely as it may be conducive to gain. Varro also speaks of it as of a wise and happy state, inclining to justice, temperance, sincerity, and all the virtues, which shelters from evil passions, by affording that constant employment, which leaves little leisure for those vices which prevail in cities, where the means and occasions for them are created and supplied."
