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.
Wild fruits and berries formed a considerable portion of the food of the earliest lacustrine peoples; and, from certain indications which have been brought to our notice, we have reason to believe that several varieties of trees were the objects of their intelligent culture; in short, that they were cultivated in orchards and gardens. The settlement of Robenhausen on the Lake of Pfæffikon, has furnished us with the most valuable information on this point. The lacustrine villages of Wangen (Lake of Constance), and Concise (Lake of Neuchâtel) have also been the scenes of curious discoveries.
In all of these settlements a large number of charred apples have been met with, cut in two, and sometimes four pieces, and evidently stored up for the winter. These apples are no larger than walnuts, and in many of the Swiss forests a species of apple still exists which appears to be the same sort as those found in the lacustrine settlements. Pears have been discovered only in the settlement of Wangen; they were cut up and dried just like the apples.
