At Meilen, Moosseedorf, and Wangen, some charred cereals have been found, viz., barley and wheat. The latter was the most abundant, and, at Wangen in particular, there were several bushels of it, either in ears or in thrashed corn collected in large heaps. These grains are almost the same shape and size as the wheat of the present time. Several ears of six-rowed barley (_Hordeum hexastichon_) were found, which differ from our common barley in having smaller grains arranged in six rows. De Candolle is of opinion that this is the species which was cultivated by the ancient Greeks, Egyptians, and Romans. This corn was preserved in large earthen vessels, as may be gathered from the contents of some of them, still in an entire state. What preparation did the corn undergo in order to render it fit for human food? On this subject we have tolerably exact data to go upon. The grain was bruised by hand, either between two stone discs or mill-stones, or in a mortar by means of a round pestle. In almost all of the lacustrine villages, some of these mill-stones made of granite or sandstone have been met with, a few of which are as much as 2 feet in diameter. M. Heer is of opinion that the grain was parched before being pounded, and then placed in vessels and slightly soaked. In this state it was fit for eating. At the time of the conquest of the Canary Islands by the Spaniards, it was remarked that the natives prepared their corn in this manner; and in the present day the inhabitants of the same regions still feed on parched grain. Nevertheless, the earliest inhabitants of western Switzerland also made real bread, or rather wheat-cakes, for leaven was not then known. Charred fragments of these loaves have been found, the grain of which is badly ground, thus affording us the opportunity of recognising the species of corn of which they are composed. These fragments are flat, and indicate that the whole cake was of a circular form. No doubt, after being bruised and wetted, the grain was made into a sort of dough, which was baked between two heated stones--a process we have previously described as having been practised in the Stone Age. In order to cultivate cereals, it was, of course, necessary for the ground to undergo some preliminary preparation. It was at least necessary to break it up so as to mellow it, and to make furrows in which to sow the seed. We are reduced to mere conjecture as to all the details of these operations, for no agricultural implements have been discovered in any of the settlements of man belonging to the bronze epoch. Perhaps, as M. Heer suggests, they made use of the stem of a tree with a projecting crooked branch, and adapted it so as to perform the functions of the plough.
