"In this connection," put in Stolo, "given the size of the farm, Cato recommends with respect to implements as follows: he who cultivates 240 jugera in olives should have five sets of oil making implements, which he enumerates severally, such as the copper utensils, including kettles, pots, ewers with three spouts, etc.; the implements made out of wood and iron, including three large wagons, six ploughs with their shares, four manure carriers, etc. So of the iron tools, what they are and how many are needed, he speaks in great detail, as eight iron pitch forks, as many hoes and half as many shovels, etc. "In like manner he lays down another formula of implements for a vineyard, viz.: if you cultivate 100 jugera you should have three sets of implements for the wine press and also covered storage vats of a capacity of eight hundred _cullei_, as well as twenty harvesting hampers for grapes and as many for corn, and other things in like proportion. "Other writers advise a smaller quantity of such conveniences, but I believe Cato prescribed so great a capacity in order that one might not be compelled to sell his wine every year, for old wine sells better than new, and the same quality sells better at one time than another. Cato writes further in great detail of the kind and number of iron tools which are required for a vineyard, such as the falx or pruning hook, spades, hoes. So also several of these instruments are of many varieties, as for instance the falx, of which this author says that there must be provided forty of the kind suitable for use in a vineyard, five for cutting rushes, three for pruning trees and ten for cutting briers." So far Stolo, when Scrofa began again. "The owner should have an inventory of all the farm implements and equipment, with a copy on file both at the house and at the steading, and it should be the duty of the overseer to see that everything is checked against this inventory and is assigned its appropriate keeping place in the barn. What cannot be kept under lock and key should be kept in plain sight, and this is particularly necessary in respect of the utensils which are used only at intervals, as at harvest time, like the grape baskets and such things, for what ever one sees daily is in the least danger from the thief." 3° CONCERNING THE OPERATION OF A FARM XXIII. "And now," interposed Agrasius, "as we have discussed the two first parts of the four-fold division of agriculture, namely: concerning the farm itself and the implements with which it is worked, proceed with the third part." _Of planting field crops_
