And this reminds me to conclude--where possibly I should have begun--with the remarkable pedigree of the state itself. Stretching across Canada, north of the St. Lawrence, and ending in the regions about the source of the Mississippi, is a range of low granite hills called the Laurentian Highlands. These hills are really mountains that are almost worn out, for they are the oldest land in America, and, according to Agassiz, the oldest in the world. In the days when there was nothing but water on the face of the globe, these mountains came up--a long island of primitive rock with universal ocean chafing against its shores. None of the other continents had put in their appearance at the time America was thus looking up. The United States began to come to light by the gradual uplifting of this land to the north and the appearance of the tops of the Alleghanies, which were the next in order. Later, the Rockies started up. The United States grew southward from Wisconsin and westward from Blue Ridge. An early view of the country would have shown a large island which is now northern Wisconsin, and a long, thin tongue of this primitive rock sticking down from Canada into Minnesota, and these two growing states looking out over the waters at the mere beginnings of mountain-ranges east and west. They were waiting for the rest of the United States to appear. As the heated interior of the earth continued to cool and contract, and the water-covered crust sank in some places, and kept bulging up higher in others, the island of northern Wisconsin continued to grow, and the Alleghanies came up with quite a strip of territory at their base. The western mountains made no progress whatever; it was as if they had some doubt about the matter. A view at another stage of progress would have shown Wisconsin and Minnesota entirely out, and pulling up with them the edges of adjoining states, and a strip along the Atlantic about half as wide as New York or Pennsylvania. Still no United States. There was water between these two sections and some islands scattered about in the south. The western mountains had not been progressing at all; they lagged behind for aeons. These two sections, beginning with Wisconsin and Minnesota in the west and the Alleghanies in the east, kept reaching out till they made continuous land; and thus Ohio and all those states between are some ages younger. But they are much older than the west; for at a time when the whole eastern half of the continent had long appeared, the Gulf Stream was flowing across the west, and the waters were depositing the small sea-shells which make the calcareous matter under Kansas loam. All that country is much younger, and the western mountains are as big as they are simply because they have not had time to become worn down. As to Florida, it was a mere afterthought, an addition built on by coral insects.
