In a few cases copper tools have been recovered which may have served for digging in the ground, but in most cases their art furnished them nothing higher than spades, shovels, picks, and hoes made of stone, horn, bone, and probably wood. In this cut are specimens of such agricultural tools. These were doubtless furnished with handles of wood. The notched one was perhaps provided with a handle at right angles to it, so as to constitute a hoe. That we are right in regarding these implements as agricultural tools, is shown not only by their large size, but also by the traces of wear discovered on them. We must admit, however, that agriculture carried on with such tools as these, must have been in a comparatively rude state. In this connection we must refer to the garden beds noticed in some places. We read that in Western Michigan the so-called garden beds are a distinguishing feature of the ancient occupation, often covering many acres in a place, in a great variety of forms, both regular and grotesque.101 These seem from the above account to be very similar to the garden beds of Wisconsin. Dr. Lapham tells us that in the latter State they consist of low, broad, parallel ridges, as if corn had been planted in drills. The average four feet in width, and the depth of the walk between them is six inches. Traces of this kind of cultivation are found in various parts of the State. We are also referred to the presence of garden mounds in Missouri, but in this case the low mounds are of the same mysterious class that Prof. Forshey says occur by millions in the South-west, and may not be the work of man. Just what the connection is between the garden beds and the Mound Builders is hard to determine. Mr. Lapham thinks that those in Wisconsin were certainly later in date than the mounds. He observed that they were frequently constructed right across the works of the Mound Builders. This would seem to imply that the makers were not one and the same people.
