"As if," remarked Pica, "there were not many of them here in town. But perhaps those who have pigeon houses on their roofs do not seem to you to be justified in calling them [Greek: peristereonas] even though some of them represent an investment of more than one hundred thousand sesterces. I advise you to buy out one of them and learn how to pocket a profit here in town, before you build on a large scale in the country." _Of turtle doves_ VIII. "So much for that then," said Axius. "Proceed, please, to the next subject, Merula." "For turtle doves," said Merula, "in like manner a house should be constructed proportioned to the number you intend to feed, and this, like the pigeon house, I have described, should have a door and windows and fresh water and walls and a vaulted roof, but in place of breeding nests the mutules should be extended through the walls or poles set in them in regular order with hempen mats on them, the lowest rank being not more than three feet from the floor, the rest at intervals of nine inches, the top rank six inches from the vault, and of equal breadth as the mutule stands out from the wall. On these the doves are fed day and night. For food they are given dry wheat, usually a half modius for every one hundred and twenty doves. Every day the house should be cleaned out, that they may not be injured by the accumulation of manure, and because also it has its place in the economy of the farm. The best time for fattening doves is about the harvest, for then the mothers are in their best condition and produce young ones not only in the largest number but the best for cramming: so that is the time when they are most profitable." _Of poultry_ IX. "Tell me now, if you please, Merula," said Axius, "what I should know of raising and fattening poultry and wood pigeons, then we can proceed to the discussion of the remainder of our programme." "There are three kinds of fowls usually classed as poultry," replied Merula, "dunghill fowl, jungle fowl and guinea fowl. The dunghill fowl are those which are constantly kept in the country at farms. "He who wishes to establish an [Greek: ornithoboskeion] from which, by the exercise of intelligence and care, he can take large profits, as the people of Delos do with such great success,[180] should observe five principal rules: 1° in regard to buying, what kind and how many he will keep: 2° in regard to breeding: 3° in regard to eggs, how they are set and hatched: 4° in regard to chicks, how and by whom they are reared, and 5°, which is a supplement of all the foregoing, how they are fattened. "The females of the dunghill fowl are called hens, the breeding males cocks, and the males which have been altered capons. Cocks are caponized by burning the spurs[181] with a hot iron until the skin is broken, the wound being poulticed with potters' clay.
