L. The word harvest (_messis_) is properly used with respect to the ingathering of those crops which are reaped, and from this action (_metere_) its name is derived, but it is mostly used in respect of corn. There are three methods of harvesting corn, one as in Umbria, where they cradle the straw close to the earth and shock up the sheaves as they are cut: when a sufficient number of shocks has been made, they go over them again and cut each sheaf between the spikes and the straw, the spikes being thrown into baskets and sent off to the threshing floor, while the straw is left in the field and stacked. A second method of harvesting is practised in Picenum, where they have a curved wooden header[96] on the edge of which is fixed an iron saw: when this instrument engages the spikes of grain it cuts them off, leaving the straw standing in the field, where it is afterwards cut. A third method of harvesting, which is used in the vicinity of Rome and in most places, is to cut the straw in the middle and take away the upper part with the left hand (whence the word to reap [_metere_] is, I think, derived from the word _medium_--connoting a cutting in the middle). The lower part of the straw which remains standing is cut later,[97] while the rest, which goes with the grain, is hauled off in baskets to the threshing floor and there in an airy place is winnowed with a shovel (_pala_) from which perhaps the chaff (_palea_) takes its name. Some derive the name of straw (_stramentum_) from the fact that it stands (_stare_), as they think the word _stamen_ is also derived, while others derive it from the fact that it is spread (_strare_), because straw is used as litter for cattle. The grain should be harvested when it is ripe: it is considered that under normal conditions and in an easy field one man should reap almost a jugerum a day and still have time to carry the grain in baskets to the threshing floor. _The threshing floor_
