Bv Professor ARNOLD HENRY GUYOT, LL.D., COR. MEM. A.G.S.S. Delivered February 16, 1860. Gentlemen of the American Geographical Society: Less than a year has elapsed since we assembled in this place to express our sorrow at the death of Humboldt, and to pay a just tribute of honor to his glorious memory, as to one who, for half a century, stood before the world as the embodi- ment and fit representative of all modern progress in the knowledge of the Physical Globe ; and here we come to-day, once more to mourn the loss of another great Master in our beloved science,—I might say the other great Master in the Science of the Globe,—Carl Ritter, the world-renowned author of the classical ‘““Erdkunde,” or the Science of the Globe in its relations to nature and to the history of mankind. Humboldt, who first entered the scene of life and of his labors, first also left it on the 6th of May, 1859, at the advanced age of 90 years; and before another season was over, on the 28th of September last, soon after the close of his 80th year, Ritter followed him into a better world. The two high-priests of the temple of Nature and of History have thus received the last summons from on high. When called, both were found still actively engaged in their high functions. They have obeyed the call; they are gone; but the temple that they have reared and beautified, and the Mighty One to whom it is consecrated, subsist, and both will last forever. It is not in death alone that they are thus associated. Sons of the same mother country, living to the last in the same city,—in the city of Berlin, that great metropolis of German science,—united by ties of affection and by feelings of a deep mutual esteem and regard, they still live united in the mem- ory of men. For the last forty years the names of Humboldt and Ritter, constantly associated, have been household words with every one interested in Geographical studies. With them is connected, in the minds of all, the idea of a gigantic progress in the science of the globe,—a progress due not only to the addition of new facts, but, as is especially the case with Ritter’s name, to a new dignity conferred upon that science by a more philosophical method, by the elevated stand-point from which it is viewed and treated, and by the living, harmo- 26 Guyot on Carl Ritter. nious connection that has been established between it and the sister sciences. To these great minds also is traced, as to its main source, that reform movement which has impressed its stamp upon all the geographical literature of the day in Ger- many, has penetrated into every school, and the mighty flood of which, flowing over its primitive boundaries, has covered Scandinavia, Switzerland, now reaches England, and, I am happy to say, is making rapid progress in this country. A conviction so uttiversal, so deeply rooted in the pop- ular consciousness, especially in that of the German nation, which reared them and received their immediate teachings, of that people endowed with so keen a power of appreciation of all kinds of scientific merit, can but correspond to a reality. That great progress cannot be denied. It is evident to the eye of every one who has had an opportunity of comparing the condition of geographical knowledge at the present day with that of half a century ago ; that is, before and after the period of the activity and controlling influence of Humboldt and of Ritter. But what seems less evident, less distinctly established in the minds of many, is the character of the peculiar element of progress contributed to geographical science by each of these two great Reformers. The brilliant services, so recently discussed before you, rendered to the science of Terrestrial Physics by Humboldt the geographer and geologist, by Humboldt the physicist and meteorologist, by Humboldt the botanist and zoologist, by Humboldt the scientific discoverer of the New World and the experienced scientific traveller in Central Asia, by Humboldt the author of the Cosmos, are present to the minds of all. The physics of the Globe, that noble science, last born, but not least, among her sister sciences, owes him, as I have said elsewhere, its present shape and its best results. This remains his chief, his most glorious title to the gratitude of the scien- tific, and his labors mark the beginning of a new era, from which the knowledge of our physical globe, as a grand harmo- nious whole, will have to date its future steps in the career of progress. How warmly Ritter acknowledged the high merit and admired the researches of Humboldt, bow fully he appreci- ated their value, and joyfully hailed every new result obtained by his ingenuity, appears, among others, in a page of the Introduction to his great book, the “Zirdkunde,” especially devoted to Humboldt’s labors, and in which he declares that without such a foundation as that furnished by the works of Guyot on Carl Ritter. Q7 Humboldt, his own work would have been impossible. But that very declaration shows that the work that he himself con- ceived and virtually performed, was still another than that attempted by Humboldt. For him the full knowledge of the physical globe, grand as it is in itself, is but a means, not an end. Our planet is a living organization which comprises the life of mankind. ‘The central idea of the ‘“Hrdkunde,” there- fore, the inward principle upon which it rests, the principle of order which binds together all its parts, is that of a vital union of nature and of man into an organic unity. Its main task is the study of the unceasing, ever-renewed, and varied mutual action of these two factors. That idea must be clearly appre- hended and well defined ; it must be seized in its fruitful applications, in its rich consequences, before one can justly appreciate its full value, and understand the profound revolu- tion that it has effected. Such a true appreciation alone will account for the vast influence that Ritter exerted upon his age, and for the fact that all thinking Germany dates, from the appearance of the ‘‘Hrdkunde,” the emancipation of Geogra- phy as an independent science, in the high sense of the term, possessed since of a principle of its own, and which takes its yank side by side with its sister science, the Philosophy of History. You will agree with me, gentlemen, when I say that, great and well deserved as is Ritter’s reputation in this country, it is—as all great reputations, indeed, but perhaps more so than usual—one resting upon authority. It is, if I may be allowed the expression, an imported one ; and this, indeed, is not sur- prising; and we could scarcely speak otherwise of England, and still more of France. Ritter’s theoretical ideas and methods are to be taken from a few academic memoirs, but more especially from his great work itself. There we find them realized in the rich, concrete forms of life. They never have been reduced by him into a regular abstract system or doctrine, a form altogether uncongenial to a mind which was so thoroughly filled with the vivid images of nature. These channels, together with his suggestive lectures to thousands of students during the long period of his public teaching, were sufficient to spread his spirit in Germany. But they are not so for foreign countries. The original memoirs just mentioned, though since published separately, are not of easy access. The very bulk of his main work has prevented, thus far, a translation of it into foreign languages, except, strange to say, one into the Russian, and a very partial one into the French. 28 Guyot on Carl Ritter. How many, in this busy world of America, will attempt the careful reading of the nineteen volumes, the twenty thousand pages of close text, which compose the portion of the ‘‘ Lrd- kunde” now published ; and that, too, in that rich, beautiful, but by no means easy tongue of Germany. These, I con- fess, are real obstacles much to be regretted, but which ought to be overcome, and ought not to be allowed to cut us off from the abundant stores of knowledge accumulated by that great scholar. . ou have honored me, gentlemen, with a request to address you upon this occasion on the life and the works of Carl Ritter. I thank you for this privilege, for such I feel it to be. I responded to the call, however, with no small degree of diffidence. But aroused in my University days, by the teachings of that venerable and much beloved friend, to the study of his favorite science, which soon became mine; guided in further steps by his kind, affectionate, and ever-ready advice ; cheered on at every stage of my scientific career by his deep sympathy, and the spontaneous expression of an unqualified approval—the last of which, traced a few days before the cold hand of death took the pen from his hand, has for me the solemn significance of his scientific will ;—loaded with such favors on his part, I felt that no personal considera- tion could justify me in declining the opportunity thus offered publicly to express the feelings of deep gratitude, and almost filial affection, which bind me to that great man, and at least to attempt to do justice before you to his claim to the grati- tude of cultivated mankind. The task, however, as the nature of the subject may soon prove to you, is not an easy one, and it is in all sincerity, and more for his memory than for myself, that I must beg your indulgence for my willing, but perhaps inadequate, efforts. The life of Ritter offers no great or stirring events. It is modest and serene, like himself. But it derives a peculiar interest from the circumstances by which a watchful Provi- dence afforded, contrary to human expectation, the means best appropriate to a full development of the faculties with which he was endowed, and from his readiness eagerly and faithfully vo improve every opportunity thus offered to him. Carl Ritter was born on the 7th of August, 1779, in the ~ city of Quedlinburg, the birthplace of the great poet, Klop- stock, in the mountainous region of the Harz, in Prussian Saxony. He thus belongs, by the first twenty years of his life, so decisive for the character of every man in after life, to Guyor on Carl Ritter. 29 the end of the eighteenth century, that remarkable era which can be called emphatically the mother of the present age. There are, indeed, in the life of mankind, as in all that lives, critical times, in which it seems as if the fountains of life are stirred up to their very depths, and in which the forces of life are aroused to bring forth new productions more abun- dant and more beautiful. Such a stirring age was the end of the eighteenth century. It severs itself from the traditions of the past, which fetter instead of fostering human progress. It returns to the depth of human consciousness, in order to place itself on a basis at once more true and more solid. It turns its eyes, with the most sanguine hopes, towards an unknown future. A noble, sincere enthusiasm, ready for all sacrifices, selzes upon every soul, and imparts to the whole movement a dignity which its worst excess can mar, but not efface. It is truly a time of youthful renovation of the elements of human civilization, a creative age to which we may trace the beginning of all the progress of which our age can boast. In every direction a host of noble pioneers strike new paths in the old, desolate fields, as well as in the new, untrodden ones, with the hopeful daring and vigor of youth, unaware of coming dangers, unmindful of difficulties. The French and American Revolutions in social science, Kant in philosophy, Schiller and Goethe in literature, Lavoisier in chemistry, Volta, Oerstedt in physics, Herschell in astronomy, Werner and Von Buch in geology, Humboldt in terrestrial physics, De Jussieu and De Candolle in botany, Cuvier in zoology, Ritter, at last, in geography, all begin, in each of these grand departments of human culture, a new era, the era in which we live ; and it is on the foundation laid down by these glorious sons of the great moventent of the eighteenth century, that we rear the splen- did edifice which is the glory of the nineteenth. The birth of Ritter, in such a time and such an atmos- phere, can fitly be termed, in view of his future calling, a providential event. Ritter’s father was a physician, much esteemed for his skill and the noble qualities of his mind and heart. He died young, and Ritter’s mother, a highly educated woman, remained a widow with five children, without any means to educate them. But help soon came, as providential help al- ways does, from the quarter from which it could least be expected. The Prince of Bernburg took charge of the eldest son, ten years old. A distinguished, enthusiastic educator, Salzman, previously unacquainted with the family, requested 30 Guyot on Carl Ritter. the mother to intrust to him her young Carl, then five years old ; and Carl became the first pupil of the just opened and since celebrated school at Schnepfenthal, near Gotha, in Sax- ony, which still glories in having reared that great scholar. Under the enlightened guidance and loving care of Salzman and his associate, the noble-hearted Gutsmuths, the former family instructor of Dr. Ritter’s children, and a system of education, the object of which was to develop and invigorate the body as well as the mind and heart, the child grew to a happy, amiable, pure-minded young man. In that lovely valley, which Ritter always considered as his true home, at the foot of the Thuringian forest, far from the artificial life of cities, but surrounded by a charming and most varied scenery, he formed, at an early age, that intimate acquaintance with nature, and imbibed that love for the beauties of God’s cre- ation, which breathes in all his works. At the age of sev- enteen, when the question of his immediate future began to be- come an earnest one, Providence again provided for him. A rich merchant from Frankfort-on-the-Main, Mr. Hollweg, a partner in the large firm of Bethman, visited the school, and became so much interested in the young Ritter that he offered to send him for two years to the University, on condition that he would, after that time, take charge, in his own house, of the instruction of his children. The offer was accepted, and Ritter became, in November, 1796, a student at the University of Halle. In 1798, he entered upon his duties in Mr. Hollweg’s house in Frankfort, and with his characteristic, upright earnestness, devoted to the work before him his best energies. The most signal success crowned his efforts, and the strong ties of mu- tual affection which were formed between him and his pupils and lasted to the day of his death, a just and sweet reward for his devotion, honor both the pupils and the instructor. Of the two sons of Mr. Hollweg the elder died in his youth; the other, a worthy pupil of such a teacher, is now the Minister of Public Instruction and Worship in Prussia, the noble-minded Von Bethman-Hollweg, the representative, in this high and influential position, of the liberal and enlightened tendencies of our age. In the education of a third pupil, the son of the celebrated 8. Th. Soemmering, he met with equal success. The situation of Ritter in Frankfort, and his connec- tion with that wealthy and highly cultivated family, had a great influence on his life and his general development, Opportunities for improvement, rarely enjoyed to an equal degree by one placed in his early circumstances, opportu Guyor on Carl Ritter. 31 nities eagerly embraced by his ready and conscientious mind, were now offered to him. The qualities of his mind and heart had soon won for him in the family the position of an esteemed and affectionate friend. As such, and as an inmate of the house, he came in contact with the most re- fined society, and many of the most distinguished men of the age, who repaired to the house of Hollweg as to a common centre. Here was begun his acquaintance with such men as Humboldt, as the great geologist, Leopold von Buch, with the suggestive, truly philosophical 8. Th. Soemmering, to whom he modestly refers, in the Introduction to the “ Erdkunde,” the merit of having especially called his attention to the laws of the geographical relationship of all animated nature. In Frankfort, also, he formed an intimate friendship with Ebel, the genial author of “The Structure of the Earth in the Alps” and other works on Switzerland, from whom he re- ceived a fresh impulse to the study of the Globe. Mean- while, urged on by his duties towards his pupils, he embraced in his activity the most varied studies. History and the an- cient languages received from him a particular attention. He read with his friends, the eminent philologists, Matthiae and Grotefend, the prominent authors of Greece and Rome. He thus diligently accumulated from all quarters, the treasures of that vast erudition without which his future work would have been impossible. His predilection for Geography, however, becomes already apparent by the publication, in 1806, of six ‘charts of Europe, followed afterwards, in 1811, by a Geography of Europe in two volumes, In these works the author of the “ Krdkunde” is predicted, but not yet fully manifested. One element is to be added to his previous preparation, and this is a more direct acquaintance with the grand typical forms of nature and with the marvellous products of human culture. Ritter must see Switzerland and Italy—contemplate the wonders of nature and history in their very sanctuaries. That precious gift also was in store for him. From the year 1807, he repeatedly visited, with his pupils, Switzerland and Italy. The last journey, which commenced in 1811, extended over several years, and allowed him a sojourn of over a year in Geneva, and a pro- longed stay at Rome and in Italy, which he visited to its southern extremity. What a rich source of instruction these travels have been for a mind so eager to drink from the very fountains of knowl- edge, and so well prepared and matured by assiduous study 32 Guyot on Carl Ritter. and labor, may be easily conceived. Switzerland and the gigantic fabric of the Alps, which he visited again and again until a few years before his death, furnished to his plastic and vivid imagination the most accomplished type of moun- tain scenery, with which to compare all the other grand sys- tems of our Globe. The careful study of Italy and Rome, that classical soil of history and of art, clothed with the truth- fulness of life his conceptions of the past ages, and gave him a deep intuition of the adaptedness of the beautiful cli- inate, of the admirable nature, and the remarkable structure of the peninsular lands which surround the Mediterranean Sea for developing the brilliant flower of the civilization of the an- cient world. Without these rich intuitions derived directly from Nature, says Ritter himself in the Introduction to his “ Erdkunde,” his work would not have been undertaken, as without Humboldt’s labors, it could not have been performed. This remark clearly tells the high value that he attached to these personal experiences, In every country that he visited he formed an intimate acquaintance with the leading minds of the time. During his protracted stay in Geneva, that scientific metropolis of Switzer- land, he enjoyed familiar intercourse with the most eminent men of that school. De Saussure, the model scientific travel- ler and physicist of European fame, had just died, but A. Pictet, De Candolle, and many others remained. The inti- mate and fruitful friendship which soon united him to the first, no doubt contributed, together with the natural beauties of that privileged country, to cause Ritter to look upon his so- journ in Geneva as a bright spot in his life. But of all men with whom Ritter met at this period of his life, none seems to have made a deeper, a more lasting impres- sion upon him than Pestalozzi, the far-famed reformer of pop- ular education. Ritter went to visit him for a few hours in 1807, in Yverdun, at that time the place of his residence, and remained there for months. Pestalozzi’s sympathetic nature found in Ritter’s soul a full response. Ritter’s letters to him copies of some of which happen to be in my possession, are full of expressions of gratitude and of the tender regard of a son for a respected and beloved father, and of admiration for the fun- damental idea on which rests his method of teaching. His life-size portrait stood in Ritter’s lbrary. To him and to Gutsmuths, his fatherly teachers, as he calls them, and not to some high patron, he inscribes the first volume of his Genera] Geography, asa token of his reverence and heartfelt gratitude, Guyot on Carl Ritter. 33 In Rome he met with that triad of pure-minded artists, Thorwaldsen, Overbeck, and Cornelius, whose genius raised German art so high, and whose friendly intercourse gave him an enlarged view of art and a deeper insight into its nature. By the careful study of the topography of that most remarka- ble of all historical spots and its monuments, Ritter gathered copious materials for one of his most popular courses of lec- tures at the University of Berlin. The period of preparation is now over for Ritter. Eighteen years have elapsed since the close of his first education in Schnepfenthal ; eighteen years of assiduous labor in nearly all the domains of human knowledge, and of large experience in the world of nature and of man. He returns home, loaded with these new treasures, with matured views, and a clear per- ception of the grand idea, which he so gradually evolved from the depth of his rich nature, and which is to establish the sci- ence cf the globe on a new foundation and breathe into it a new spirit. But it is not enough for that great architect to have con- ceived and matured the plan, to have collected the materials for the edifice; he must rear it, realize his conception, and give it the tangible form of life. He soon sets himself at work and devotes all his energies to the performance of that arduous task that he now feels to be the work of his life. In the year 1814, he went to Geettingen with his two pupils now ripe for University studies. During two years he devoted bis new leis- ure to a faithful use of that vast University library of Goettingen, then, perhaps, the richest among the rich ones which are gath- ered in so great numbers in Germany, on that classical soil of learning. Like Humboldt, a few years later, Ritter, then, could have been seen, a man of ripe years and known already by his vast acquirements, modestly sitting among the crowd of young students, listening to courses of lectures delivered at the University on topics most varied. Here also, as elsewhere, he soon gained the esteem of those who represented the intellec- tual progress of the day in that old centre of learning; and . he enjoyed the benefit of private intercourse with most men of literary and scientific eminence at that time attached to the University. Among the last, particular mention must be made of the celebrated geologist Hausmann, with whom he remained united to the end of his days by the bonds of an in- timate friendship, and who himself died a few weeks since, in December, 1859, but a few months after the departure of his old friend. 34 Guyot on Carl Ritter. In 1816, Ritter went to Berlin, where he remained one year, busily engaged in finishing and putting to press the first edition of his General Geography, the first volume of which was published in that city by Reimer, in 1817, under the title of Die Erdkunde im Verhdltniss zur Natur und zur Geschichte des Menschen, oder Allgemeine Vergletchende Geographie, als sichere Grundelage des Studium und Unterrichts in physical- ischen und historischen Wissenschaften; ‘The Science of the Earth in its relation to Nature and to the History of Man, or General Comparative Geography as a safe foun- dation for studying and teaching Physical and Historical Sciences.” In the spring of 1817, he returned to Geettingen, where he terminated the second volume of the work, which ap- peared in 1818. j These two volumes comprised only the continents of Africa and Asia, three Books out of twelve, which were to complete the whole work. But they revealed Ritter to the world, and were sufficient to place him in the high scientific position that he has since so successfully sustained, and so usefully occupied. In a masterly Introduction, he unfolds the views which he has so gradually matured, and which are to regenerate geography and to elevate it to the rank of the science of the Globe con- sidered as a living organism. In the work itself, he practical- ly illustrates the method, at once comparative and natural, or objective, as he terms it, which is commended by the lofty stand-point at which he places himself, and from which em- bracing the totality of his subject, he tries to master all its details, to grasp their beautiful arrangement, and to reproduce it in a truthful picture before the eyes of the reader. But I beg your permission to leave for a moment all further considerations of that work, the merit and scientific in- fluence of which I shall have soon to discuss, and to say a few more words on Ritter’s life and activity subsequent to that important step in his career. Ritter’s merit was soon appreciated. The year which fol- lowed the publication of the second volume of the “‘ Erdkunde’”’ he received a call as Professor of History in the Gymnasium at Frankfort, which he accepted. In the autumn of the same year he was married, at the age of forty, to the accomplished woman who, for so many years, was the faithful and much beloved companion of his lite. In 1820, another call, the most honorable that he could receive, brought him to Berlin as Professor of Geography both at the Royal Military School and at the University, where that Guyot on Carl Ritter. 35 chair, the first, it is believed, devoted to that special branch of knowledge in any German University, was created for him ; a public acknowledgment both of Ritter’s merit and of the svientific character that had been imparted to Geography by his labors. This appointment was due to the enlightened and far-seeing Minister of Public Instruction, William von Hum- boldt, the highly gifted brother of Alexander, and to his suc- cessor, Von Altenstein, and reflects no little credit on the wis- dom of these distinguished men, to the liberal and discrimi- nating patronage of whom the cause of learning in Prussia is otherwise so much indebted. Ritter has now found the appropriate scene of action and of further progress ; the field prepared for him by Providence, as he often gratefully acknowledged, for doing the work to which he felt called. Here, in the largest of the Universities of Germany, surrounded by a crowd of young men eager for knowledge and ready for every new light, for every new ad- vance, he met with a most welcome opportunity for an appli- cation on a grand scale of the plenteous stores of learning and of scientific experience which he had been so long accumulat- ing. To impart to minds thus prepared the new truths that he possessed, was to him not only a duty, but a delight. Moreover, living in the midst of an intellectual atmosphere in which reigned a most intense life, one of the first and blessed fruits of returning peace after the long disturbed condition of Burope ; a member by his very position, and by his universal- ly acknowledged merit, of that circle of highly cultivated men, the élite of intellectual Germany, gathered in Berlin, his rich powers expanded to their natural limits, and the fruits of that long and laborious period of preparation which had preceded, came to full maturity. We may say that after the first ten years of his residence in Berlin, in the midst of such favorable circumstances, Ritter’s mind had grown to its full stature, and his scientific views had taken that definite form which they preserved to the end of his life. These constituted, indeed, the noble share of light allotted to him. Nearly thirty years more were found too short to execute the grand conception that was before him as the goal to be attained. Ritter entered upon his new duties with his usual ardoz and cheerfulness, He was bent at the same time with no less earnestness on the continuance of his publications. In the same year, 1820, he had published a volume under the title, Vorhalle Huropaeischer Voelkergeschichten vor Herodotus am Kaukasus und an den Gestaden des Pontus, or Vestibule to 36 Guyot on Carl Ritter. the history of European nations before Herodotus, around the Caucasus and on the shores of the Black Sea”—a_ subject which had grown under his pen when writing the second vol- ume of his General Geography on Western Asia. The first edition of the Lrdkunde being exhausted, the following year, 1821, was devoted to the preparation of a second, much en- larged edition, the first volume of which, containing Africa only, appeared in January, 1822, thus beginning the new series of volumes which compose the work we now possess. That first fruit of his literary activity in Berlin, as he calls it himself, was followed by a long interval of full ten years, during which he issued only two papers read before the Academy of Sciences, a very graphic and interesting description of India in the Berlin Almanac for 1824, and several smaller contributions. But that period was none the less one of intense activity for him and of paramount usefulness for the rising generation. The claims upon his talents as an academic teacher, became more and more numerous. In addition to his previous duties he took charge, from 1822, of the chair of history at the military school, left vacant by the death of his friend Woltmann. In 1825, he was intrusted with the direction of the studies of the corps of cadets. He was honored with a call to instruct in history Prince Albert of Prussia, a duty which he performed during several years. The Crown-Prince of Prussia, now Fred- erick William IV., whose taste for historical studies and bril- liant attainments in that department of knowledge are well known, held Ritter in particular esteem, and the modest scholar was not unfrequently invited, during the winter months, to deliver discourses on subjects connected with Geography and history, before a select and private circle as- sembled in the royal palace. These marks of high favor and of trust, and the growing popularity of Ritter’s lectures at the University, cheered him on in the work of diffusing, by oral teaching and by personal influence, the new views and methods in geographical science which he believed to be more conso- nant with nature itself, and helped, no doubt, the reform movement which originated with him and now began to spread itself. His lectures in the halls of the University were soon regarded as such as all students interested in true humanitary culture should hear. While a large number of officers of the Prussian army were trained by him every year, or studied under his immediate direction and influence, hundreds of stu- dents left the University, carrying with them into all parts of Germany and into all stations of life, the remembrances Guyot on Carl Ritter. 37 of his suggestive instructions, and the conviction that a new and better era had begun for the science of the Globe. Thus was prepared that renovation of Geography in the University and in the school which was demanded by the progress of the natural and historical sciences, but which awaited the genius of Ritter to assume its shape, and his guidance and spirit to produce its full effect, as it now has throughout Germany, As one who had the privilege of listening, during a period of five years (from 1830 to 1835), to nearly all his courses of lectures, I may be allowed to add my humble testimony to that of so many of his hearers who remember his teachings with delight. Ritter, indeed, as an academic teacher, during his long University career of thirty-seven years, achieved a suc- cess rarely equalled. Few can boast of a more constant pop- ularity. He came to Berlin almost unknown to the students, as was indeed the science itself that he was called upon to expound.
