In agriculture we detect only such advances as improved implements would suggest. They used the sickle in gathering in the harvest. We find no implements which we are sure were used for agricultural purposes. Yet they must have had some means of preparing the ground for the cereals. The day of wild animals was gone. In the lake settlements of this age the domestic animals outnumbered the wild species.16
During this age the horse was used for riding and driving, and oxen were used for plowing.
The proof of this fact is certain sketches found in Denmark. But the use of bronze in that country continued after iron had been introduced in the south of Europe. Pottery was more carefully made—though the wheel for turning it was not yet introduced. The shapes were varied and elegant; sometimes, instead of having a flat base, they came to a point below—in which case they had to be placed in a support before they could stand upright. Nearly all the pottery bears the ornamentation peculiar to the Bronze Age—that is, straight lines, dots, etc.
