He commenced writing for the newspapers and periodicals in 1808, in which year he also published a poetic tribute to a friend, which excited local notice, and was attributed to a person of literary celebrity. For, notwithstanding the gravity of his studies and researches, he had indulged an early poetic taste for a series of years, by compositions of an imaginative character, and might, it should seem, have attained distinction in that way. His remarks in the "Literary and Philosophical Repertory," on the evolvement of hydrogen gas from the strata of Western New York, under the name of Burning Springs, evinced an early aptitude for philosophical discussion. In a notice of some archæological discoveries made in Hamburgh, Erie County, which were published at Utica in 1817, he first denoted the necessity of discriminating between the antique French and European, and the aboriginal period in our antiquities; for the want of which discrimination, casual observers and discoverers of articles in our tumuli are perpetually over-estimating the state of ancient art.

About 1816 he issued proposals, and made arrangements to publish his elaborated work on vitreology, which, so far as published, was favorably received.

In 1817 he was attracted to go to the Valley of the Mississippi. A new world appeared to be opening for American enterprise there. Its extent and resources seemed to point it out as the future residence of millions; and he determined to share in the exploration of its geography, geology, mineralogy and general ethnology, for in this latter respect also it offered, by its curious mounds and antiquities and existing Indian tribes, a field of peculiar and undeveloped interest.

He approached this field of observation by descending the Alleghany River from Western New York to the Ohio. He made Pittsburgh, Cincinnati, and Louisville centres of observation. At the latter place he published in the papers an account of the discovery of a body of the black oxide of manganese, on the banks of the Great Sandy River of Kentucky, and watched the return papers from the old Atlantic States, to see whether notices of this kind would be copied and approved. Finding this test favorable, he felt encouraged in his mineralogical researches. Having descended the Ohio to its mouth one thousand miles, by its involutions below Pittsburgh, and entered the Mississippi, he urged his

way up the strong and turbid channel of the latter, in barges, by slow stages of five or six miles a day, to St. Louis. This slowness of travel gave him an opportunity of exploring on foot the whole of the Missouri shore, so noted, from early Spanish and French days, for its mines. After visiting the mounds of Illinois, he recrossed the Mississippi into the mineral district of Missouri. Making Potosi the centre of his survey and the deposit of his collections, he executed a thorough examination of that district, where he found some seventy mines scattered over a large surface of the public domain, which yielded, at the utmost, by a very desultory process, about three millions of pounds of lead annually. Having explored this region very minutely, he wished to ascertain its geological connection with the Ozark and other highland ranges, which spread at the foot of the Rocky Mountains, and he planned an exploratory expedition into that region. This bold and hazardous journey he organized and commenced at Potosi early in the month of November, 1818, and prosecuted it under many disadvan tages during that fall and the succeeding winter. Several expert and practiced woodsmen were to have been of this party, but when the time for setting out came all but two failed, under various excuses. One of these was finally obliged to turn back from Mine au Breton with a continued attack of fever and ague. Ardent in the plan, and with a strong desire to extend the dominions of science, he determined to push on with a single companion, and a single pack-horse, which bore the necessary camp conveniences, and was led alternately by each from day to day. A pocket compass guided their march by day, and they often slept in vast caverns in limestone cliffs at night. crystaline water frequently gushed up from the soil or rocks. This track laid across highlands, which divide the confluent waters of the Missouri from those of the Mississippi. Indians, wild beasts, starvation, thirst, were the dangers of the way. This journey, which led into the vast and desolate parts of Arkansas, was replete with incidents and adventures of the highest interest. While in Missouri, and after his return from this adventurous journey, he drew up a description of the mines, geology, and mineralogy of the country. Conceiving a plan for the better management of the lead mines as a part of the public domain, he determined to visit Washington, to submit it to the government.

Gigantic springs of the purest

Packing up his collections of mineralogy and geology, he ordered them to the nearest point of embarkation on the Mississippi, and, getting on board a steamer at St. Genevieve, proceeded to New Orleans. Thence he took shipping for New York, passing through the Straits of Florida, and reached his destination during the prevalence of the yellow fever in that city. He improved the time of his quarantine at Staten Island by exploring its mineralogy and geology, where he experienced a kind and appreciating reception from the health officer, Dr. De Witt.

His reception also from scientific men at New York was most favorable, and produced a strong sensation. Being the first person who had brought a collection of its scientific resources from the Mississippi Valley, its exhibition and diffusion in private cabinets gave an impulse to these studies in the country.

Men of science and gentlemen of enlarged minds welcomed him. Drs. Mitchell and Hosack, who were then at the summit of their influence, and many other leading and professional characters extended a hand of cordial encouragement and appreciation. Gov. De Witt Clinton was one of his earliest and most constant friends. The Lyceum of Natural History and the New York Historical Society admitted him to membership.

Late in the autumn of 1819, he published his work on the mines and mineral resources of Missouri, and with this publication as an exponent of his views, he proceeded to Washington, where he was favorably received by President Monroe, and by Mr. Calhoun and Mr. Crawford, members of his cabinet. At the request of the latter he drew up a memoir on the reorganization of the western mines, which was well received. Some legislation appeared necessary. Meantime Mr. Calhoun, who was struck by the earnestness of his views and scientific enterprise, offered him the situation of geologist and mineralogist to an exploring expedition, which the war department was about dispatching from Detroit to the sources of the Mississippi under the orders of Gen. Cass.

This he immediately accepted, and, after spending a few weeks at the capital, returned in Feb., 1820, to New York, to await the opening of the interior navigation. As soon as the lakes opened he proceeded to Detroit, and in the course of two or three weeks embarked on this celebrated tour of exploration. The great lake basins were visited and explored, the reported copper mines on

Lake Superior examined, and the Upper Mississippi entered at Sandy Lake, and, after tracing it in its remote mazes to the highest practical point, he descended its channel by St. Anthony's Falls to Prairie du Chien and the Du Buque lead mines. The original outward track north-westward was then regained, through the valleys of the Wisconsin and Fox Rivers, and the extended shores of Lake Michigan and Huron elaborately traced. In this he was accompanied by the late Professor David B. Douglass, who collected the materials for a correct map of the great lakes and the sources of the Mississippi.

It was late in the autumn when Mr. Schoolcraft returned to his residence at New York, when he was solicited to publish his "narrative journal." This he completed early in the spring of 1821. This work, which evinces accurate and original powers of observation, established his reputation as a scientific and judicious traveler. Copies of it found their way to England, where it was praised by Sir Humphrey Davy and the veteran geographer, Major Rennel. His report to the Secretary of War on the copper mines of Lake Superior, was published in advance by the American Journal of Science, and by order of the Senate of the United States, and gives the earliest scientific account of the mineral affluence of the basin of that lake. His geological report to the same department made subsequently, traces the formations of that part of the continent, which gives origin to the Mississippi River, and denotes the latitudes where it is crossed by the primitive and volcanic rocks. The ardor and enthusiasm which he evinced in the cause of science, and his personal enterprise in traversing vast regions, awakened a corresponding spirit; and the publication of his narratives had the effect to popularize the subject of mineralogy and geology throughout the country.

In 1821, he executed a very extensive journey through the Miami of the Lakes and the River Wabash, tracing those streams. minutely to the entrance of the latter into the Ohio River. He then proceeded to explore the Oshawanoe Mountains, near Cavein-Rock, with their deposits of the fluate of lime, galena, and other mineral treasures. From this range he crossed over the grand prairies of the Illinois to St. Louis, revisited the mineral district of Potosi, and ascended the Illinois River and its northwest fork, the Des Plaines, to Chicago, where a large body of

Indians were congregated to confer on the cession of their lands. At these important conferences, he occupied the position of secretary. He published an account of the incidents of this exploratory journey, under the title of Travels in the Central Portions of the Mississippi Valley. He found, in passing up the river Des Plaines, a remarkably well characterized specimen of a fossil tree, completely converted to stone, of which he prepared a descriptive memoir, which had the effect further to direct the public mind to geological phenomena.

On

We are not prepared to pursue minutely these first steps of his energetic course in the early investigation of our natural history and geography. In 1822, while the lead-mine problem was under advisement at Washington, he was appointed by Mr. Monroe to the semi-diplomatic position of Agent for Indian Affairs on the North-west Frontiers. This opened a new field of inquiry, and, while it opposed no bar to the pursuits of natural science, it presented a broad area of historical and ethnological research. this he entered with great ardor, and an event of generally controlling influence on human pursuits occurred to enlarge these studies, in his marriage to Miss Jane Johnston, a highly cultivated young lady, who was equally well versed in the English and Algonquin languages, being a descendant, by the mother's side, of Wabojeeg, a celebrated war sachem, and ruling cacique of his nation. Her father, Mr. John Johnston, was a gentleman of the highest connections, fortune, and standing, from the north of Ireland, who had emigrated to America during the presidency of Washington. He possessed great enthusiasm and romance of character, united with poetic tastes, and became deeply enamored of the beautiful daughter of Wabojeeg, married her, and had eight children. His eldest daughter, Jane, was sent, at nine years of age, to Europe to be thoroughly educated under the care of his relatives there, and, when she returned to America, was placed at the head of her father's household, where her refined dignified manners and accomplishments attracted the notice and admiration of numerous visitors to that seat of noble hospitality. Mr. Schoolcraft was among the first suitors for her hand, and married her in October, 1823.

Mr. Johnston was a fine belles lettres scholar, and entered readily
