"This work has been noticed with commendation by most of the Journals of Forestry in Europe, and has been elaborately reviewed by Dr. Schwappach, of the Bavarian Forest Administration, in a leading journal at Berlin, devoted to this science. After noticing the steps that had been taken for the appointment of a person to investigate the subject under authority of Congress, he remarks:-It excites our surprise that a man not a Specialist, should have been able, in so short a time, to so completely master the whole body of European and American Forestry literature and legislation." Pop. Science Monthly for Sept. "The Solar System and its Neighbors" is a striking and brilliant article by Dr. C. B. Warring on celestial dynamics. His views are original and most impressive, and are well calculated to exalt our estimate of the sublime fascinations of astronomy. We have another curious paper on those besotted medieval superstitions which seem absolutely incredible to modern readersit is on the "Legal Prosecutions of Animals." Animals were assumed to be responsible for their acts like people, and horses, hogs, bulls, rats, and even insects, were solemnly prosecuted, and the whole judicial apparatus of society was brought to bear upon their trials and executions. Territory, to the Yellowstone Park has been commenced, and 125 miles of it are to be completed during the year 1880, The far-famed Yosemite Valley, the Snowy Sierras, the deep gorges of the Colorado of the West, the great area of lofty mountain-peaks in Central Colorado-not surpassed by the world-renowned scenery of the Alpine districts of Europe-are now reached with comparatively little difficulty by the travel ling public. Indeed, it may now be said that the era of exploration is past for the United States and Territories, for there are now no tracts of any size that have not been examined with more or less care, and the novelty taken from them. Located in the north-western corner of Wyoming Territory, about the head-waters of the Missouri and Yellowstone Rivers, is a tract of country more remarkable for the wonderful phenomena of nature than any other region of the globe. It may very properly be called the "Northern Wonderland," in contradistinction to a similar region in New Zealand which is now known as the "Southern Wonderland." It is a singular fact that this marvellous region has been known to the world with any certainty only for a period of about ten years. Vague rumors of burning plains, boiling springs, volcanoes ejecting water and mud, great lakes, and other wonders, had indeed reached the civilized world from time to time, but as the most astounding stories of petrified forests, of animals turned to stone, and of streams flowing so rapidly that their waters became heated were intermingled with these rumors, the latter were disregarded altogether, and were looked upon as the wild vagaries of wandering mountaineers. Captains Lewis and Clarke, in their exploration of the head-waters of the Missouri in 1805, seem to have heard nothing of the marvels at the sources of the Madison and Yellowstone Rivers. The Yellowstone Lake was placed by them on the map as a large body of water, but they had no personal knowledge yet, their information having been, in all probability, derived from the Indians. The first trustworthy accounts that made an impression on the public were given by a small party under General Washburn, the surveyorgeneral of Montana, and escorted by a small Basaltic Columns near Lower Falls East Park of Yellowstone. "Within the last decade the remarkable scenery of the Rocky Mountain region has become more and more familiar to the travelling public, and as the facilities for reaching every portion of our great West are increasing every year, those portions which have hitherto been considered accessible only to the adventurous explorer or pioneer will soon be easily reached by the general public. Already a railroad from Cheyenne, Wyoming body of United States soldiers under Lieutenant G. C. Doane, in 1870. This party spent about a month in these interesting localities. Hon. N. P. Longford the same year gave a popular account of these phenomena in Scribner's Cooking Fish in the Fishpot, on Yellowstone Lake. Monthly, which excited great interest. Many other expeditions, official and unofficial, too numerous to mention in this connection, have since visited this region. During the seasons of 1871 and 1872 the writer conducted a thoroughly or ganized corps in this district, and made a syste matic survey of it. The official report of the expedition of 1871, published by the government, created so great an interest among the people that, through the efforts of the writer, in February, 1872, Congress was induced to pass an act withdrawing from settlement, occupancy, or sale under the laws of the United states an area a out the urces of the Yellowstone River e bracing alont thirty-five hundred square miles, dedicating and setting it apart as a public park or pleasureground for the benefit and enjoyment of the people. Up to the time of these exploration s the great Divide or water shed of the continent was probably the least known region in America although it exceeds all other regions in geographical as well as geological in terest. So much information of a strictly scien tific character was obtained at the time, so many new streams and lakes were surveyour knowledge of said to have been Some of the most remarkable and instructive fea. tures in North America. It forms the very apex or divide of the continent. Within a radius of twenty-five miles may be found the sources of three of the largest rivers in America. The general elevation is from six to eight thousand feet above sea-level, while the mountains, the eternal snows of which form the sources of the great rivers just mentioned, rise to the height of from ten to twelve thousand feet. Flowing northward are the numerous branches of the Missouri, Yellowstone and Wind rivers, all of which eventually unite in one great stream, the Missouri: to the south are the branches of Green River, which latter unites with the Colorado and finally empties into the Gulf of California; while south and west flow the branches of Snake River, which, joining the Columbia, pour their vast volume of water into the Pacific. The Yellowstone Lake, which is one of the most beautiful bodies of water on the continent, is always of a deep emerald-green color, and is set like a gem amid the surrounding volcanic mountain peaks. On the south side of the lake, not more than half a mile distant from it, and not over three hundred feet above the level of its surface, is the Divide between the drainage of the Atlantic and Pacific slopes. It would require but little labor to turn the waters of miles, within which four hundred and seventy mountain peaks worthy of a name can be distinctly seen. The area swept by the eye from this point cannot be much less than from thirty to fifty thousand square miles, embracing portions of Wyoming, Montana, Idaho and Utah, and exhibiting every variety of the grandest and most beautiful scenery. Ten large lakes and several Crystal Falls, Cuscade Creek, Yellowstone Park, 129 Feet. the lake into Snake River. Here is located the celebrated Two-Ocean Pass, where at certain seasons of the year the waters of the same channel separate, a portion flowing in either direction. From the summits of the snow-capped peaks surrounding the lake the view is grand beyond description. From the top of Red Mountain, on the south side, the scope of vision embraces a circle having a radius of one hundred and fifty smaller ones are taken in by this view, and the entire Yellowstone Park is spread out under the eye. The purity of the atmosphere in these high latitudes is well known, so that these statements will not seem exaggerated. On the east side of the Yellowstone River, between the first and second canons, we find one of the most symmetrical and remarkable ranges of mountains to be seen in the West. This range was called the |
