Show A WORLD'S FAIR MAP. When FlnUhed It Will Cover Nearly an Acre of Ground. The United States geological survey has been for ten years engaged in making mak-ing a great map of the United States, parts of which will be on exhibition at the world's fair. The piece, six feet in length and four feet in width, now ready, includes the state of Connecticut and a bit of Long Island and eastern New York. This vast map will take at least twenty-five more years to complete. com-plete. Its detail is such that upon it will be indicated every stream, brook, hillock, mountain, valley, farm, village and city. It will show every public and private road as completely as a surveyor's survey-or's map of a small township. This map, when completed, would, if spread out, cover a little over three-quarters of an acre in superficial area. Of course it would be impossible to suspend such a map as to make it available for practical use, and therefore' it will have to be published in sections. In addition to this piece of the map of the United States the geological survey sur-vey is preparing an outline map of the country, which will also be exhibited at the fair. It is to be spherical in shape. By it at a glance the different elevations, the tablelands, the mountain ridges and the valleys will be indicated in the outline, out-line, the highest peaks of the mountains moun-tains being proportionately elevated as much above the sea level as are the peaks of the Rocky mountains above the Atlantic and Pacific coast lines. |
