"I do not think that those authors should be imitated in that," said Stolo, "for I deem them to have done better who have confined the subject to the straitest limits, excluding all considerations which are not strictly pertinent to the subject. Wherefore the subject of grazing, which many writers treat as a part of agriculture, seems to me to belong rather to a treatise on live stock. That the occupations are different is apparent from the difference in the names of those we put in charge of them, for we call one the farmer (_villicus_) and the other the herdsman (_magister pecoris_). The farmer is charged with the cultivation of the land and is so called from the _villa_ or farm house to which he hauls in the crops from the fields and from which he hauls them away when they are sold. Wherefore also the peasants say _vea_ for _via_, deriving their word for the road over which they haul from the name of the vehicle in which they do the hauling, _vectura_, and by the same derivation _vella_ for _villa_, the farm house to and from which they haul. In like manner the trade of a carrier is called _vellatura_ from the practice of driving a _vectura_, or cart." "Surely," said Fundanius, "feeding cattle is one thing and agriculture is another, but they are related. Just as the right pipe of the _tibia_ is different from the left pipe, yet are they complements because while the one leads, it is to carry the air, and the other follows, it is for the accompaniment." "And, to push your analogy further, it may be added," said I, "that the pastoral life, like the _tibia dextra_, has led and given the cue to the agricultural life, as we have on the authority of that learned man Dicaearchus who, in his _Life of Greece_ from the earliest times, shows us how in the beginning men pursued a purely pastoral life and knew not how to plough nor to plant trees nor to prune them; only later taking up the pursuits of agriculture; whence it may be said that agriculture is in harmony with the pastoral life but is subordinate to it, as the left pipe is to the right pipe." "Beware," exclaimed Agrius, "of pushing your musical analogy too far, for you would not only rob the farmer of his cattle and the shepherd of his livelihood but you would even break the law of the land in which it is written that a farmer may not graze a young orchard with that pestiferous animal which astrology has placed in the heavens near the Bull."
