The last or nearly the last book he wrote was the treatise on agriculture, _De Re Rustica_, which has fortunately come down to us entire; and with the kindred works of Cato and Columella, forms one of the most deeply interesting products of the Roman mind. It is in three books: the first dedicated to his wife Fundania, the second to Turanius Niger, the third to Pinnius. Varro was in his 81st year when he drew upon his memory and experience for this congenial work, 36 B.C. The destruction of his library had thrown him on his own resources to a great extent; nevertheless, the amount of book-lore which he displays in this dialogue is enormous. The design is mapped out, as in his other treatises, with stately precision. He meets some friends at the temple of Tellus by appointment with the sacristan, "_ab_ aeditimo, _ut dicere didicimus a patribus nostris; ut corrigimur ab recentibus urbanis, ab_ aedituo." These friends' names, Fundanius, Agrius, and Agrasius, suggest the nature of the conversation, which turns mainly on the purchase and cultivation of land and stock. They are soon joined by Licinius Stolo and Tremellius Scrofa, the last- mentioned being the highest living authority on agricultural matters. The conversation is carried on with zest, and somewhat more naturally than in Cicero's dialogues. A warm eulogy is passed on the soil, climate, and cultivation of Italy, the whole party agreeing that it exceeds in natural blessings all other lands. The first book contains directions for raising crops of all kinds as well as vegetables and flowers, and is brought to an abrupt termination by the arrival of the priest's freedman who narrates the murder of his master. The party promise to attend the funeral, and with the sarcastic reflection _de casu humano magis querentes quam admirantes id Romae factum_, the book ends. The next treats of stock (_de re pecuaria_), and one or two new personages are introduced, as Mennas, Murius, and Vaccius (the last, of course, taking on himself to speak of kine), and ends with an account of the dairy and sheep-shearing. The third is devoted to an account of the preserves (_de villicis pastionibus_) which includes aviaries, whether for pleasure or profit, fish-tanks, deer- forests, rabbit-warrens, and all such luxuries of a country house as are independent of tillage or pasturage--and a most brilliant catalogue it is. As Varro and his friends, most of whom are called by the names of birds (Merula, Pavo, Pica, and Passer), discourse to one another of their various country seats, and as they mention those of other senators, more or less splendid than their own, we recognise the pride and grandeur of those few Roman families who at this time parcelled out between them the riches of the world. Varro, whose life had been peaceful and unambitious, had realized enough to possess three princely villas, in one of which there was a marble aviary, with a duck-pond, bosquet, rosary, and two
