II. The discoveries in Asia may in general be divided into those which the vast possessions of the Russians in this quarter of the globe, and the corresponding interest which they felt to become better acquainted with them, induced them to make, and into those to which the English were stimulated, and which they were enabled to perform, from the circumstance of their vast, important, and increasing possessions in Hindostan.
The most important and instructive travels which spring from the first source, are those of Bell of Antermony, Pallas, Grnelin, Guldenstedt, Lepechin, &c. Bell was a Scotchman, attached to the Russian service: his work, which was published about the middle of the last century, contains an account of the embassy sent by Peter the Great to the emperor of China, and of another embassy into Persia; of an expedition to Derbent by the Russian army, and of a journey to Constantinople. Of the route in all these directions he gives an interesting and accurate account, as well as of the manners, &c. of the people. Indeed, it is a valuable work, especially that portion of it which conducts us through the central parts of Asia,--an immense district, which, as we have already remarked, is not much better known at present, (at least considerable portions of it,) than it was three or four centuries ago. The travels of Pallas, &c. were undertaken by order of the Russian government, for the purpose of gaining a fuller and more accurate account of the provinces of that immense empire, especially those to the south, which, from climate, soil, and productions were most valuable, and most capable of improvement.
The English possessions in Hindostan have led the way to two sets of discoveries, or rather advancements in geographical knowledge: one which was derived from the journies frequently made overland from India to Europe; and the other, which was derived from embassies, &c. from Calcutta to the neighbouring kingdoms. In general, however, the journies overland from India, having been undertaken expressly for the purpose of expedition, and moreover being through countries which required the utmost caution on the part of the travellers to preserve them from danger, did not admit of much observation being made, or much information being acquired, respecting the districts that were passed through. The travels of Jackson, Forster, and Fitzclarence, are perhaps as valuable as any which have been given to the public respecting the route from India to Europe, and the countries, and their inhabitants, passed through in this route.
From the embassies and the wars of the British East India Company in Hindostan, we have derived much valuable information respecting Persia, Thibet, Ava, Caubul, &c.; and from their wars, as well as from the institution of the Asiatic Society, and the facilities which their conquests afforded to travellers, the whole of the peninsula of Hindostan, as well as the country to the north of it, as far as Cashmere and the Himaleh mountains, may be regarded as fully explored. Perhaps the most valuable accession to geographical knowledge through the English conquests, relates to these mountains. They seem to have been known to Pliny under the name of Imaus: they are described by Plotemy; and they were crossed by some of the Jesuit missionaries about the beginning of the seventeenth century; but they were not thoroughly explored till the beginning of the nineteenth. Mr. Moorcroft was the first European, after the missionaries, who penetrated into the plains of Tartary through these mountains. The fullest account, however, of the singular countries which lie among them, is given by Mr. Frazer, who in 1814 passed in a straight line, in a direction of this chain, between 60 and 70 miles, and also visited the sources of the Ganges.
Our commerce with China for tea, and the hope of extending that commerce to other articles, produced, towards the end of the last century and the beginning of this, two embassies to China, from both of which, but especially from the first, much additional information has been gained respecting this extensive country, and its singular inhabitants; so that, regarding it and them, from these embassies, and the works of the Jesuit missionaries, we possess all the knowledge which we can well expect to derive, so long as the Chinese are so extremely jealous of strangers.
The British embassies to China, besides making us better acquainted with this country, added no little to our information respecting those places which were visited in going to and returning from China. Perhaps the most important correction of geography is that which was made by Captains Maxwell and Hall, who took out the second embassy: we allude to what they ascertained respecting the kingdom of Corea. They found a bay, which, according to the charts of this country, would be situated 120 miles in the interior; and at the same time they ascertained, that along the southern coast of Corea there was an archipelago of more than 1000 islands. These discoveries; the valuable additions which were made during the voyage of Captain Maxwell to the geography and hydrography of the Yellow Sea; the correction of the vague and incorrect notions which were long entertained respecting the isles of Jesso and the Kuriles, by the labours of La Perouse, Broughton, Krusentein, &c., and the full and minute information given to the public respecting Java, and other parts of the southern Indian archipelago, by Raffles, Craufurd, &c. seem to leave little to be added to our geographical knowledge of the eastern and southeastern portions of Asia.
III. We come now to America;--and though Africa is one of the most ancient seats of the human race, and of civilization and science, and America has been discovered only about 350 years, yet we know much more respecting the coasts and interior of the latter than of the former portion of the globe.
Although the Spaniards and Portuguese, who, till very lately, possessed nearly the whole of South America, guarded their possessions strictly from the curious intrusion of foreigners, and were themselves very sparing in giving to the world the information respecting them which they must have acquired,--yet, even during their power there, the geography of this part of America was gradually developed and extended; the face of the country; the great outline of those immense mountains, which, under the torrid zone, are visited by the cold of the Pole; the nature of the vast plains which lie between the offsets of these mountains; and the general direction of the rivers, not less remarkable for their size than the mountains and plains, were generally known. The geography of South America, however, taking the term in the most philosophical and comprehensive sense, has been principally enriched within these few years, by the labours of Humboldt and his fellow-traveller Bompland, of Depons, Koster, Prince Maximilian, Luccock, Henderson, and by those Englishmen who joined the Spanish Americans during their struggle with the mother country. From the observations, enquiries, and researches of these travellers, our information respecting all those parts of South America which constituted the Spanish and Portuguese dominions there, especially of Mexico, Terra Firma, Brazil, and Buenos Ayres, and generally the eastern and middle portions, has been much extended, as well as rendered more accurate and particular. Humboldt, especially, has left little to be gleaned by any future traveller, from any of those countries which he has visited and described.
The rapid and wonderful increase in the territories and inhabitants of the United States, has necessarily laid open the greater part of North America to our acquaintance. The United States, limited in their wish and endeavours to extend themselves on the north by the British possessions there, and on the south by the Spanish territories, and moreover drawn towards the interior and the shores of the Pacific by the grand natural navigation which the Mississippi and its numerous streams afford for inland commerce, and by the commercial access to the wealth of the East which the possession of the shores of the Pacific would open to them, have pushed their territories towards the west. First, the Alleghany Mountains, a feeble barrier to an encreasing population, and a most enterprising as well as unsettled people, were passed; then the Mississippi was reached and crossed; and at present the government of the United States are preparing the way for extending their territories gradually to the Western Ocean itself, and for spreading their population, as they go westwards, to the north and the south, as far as their limits, will admit.
All those countries, over which they have spread themselves, are of course now well known, principally from the accounts published by Europeans, and especially Englishmen, who have been tempted to explore them, or to settle there. The government of the United States itself has not been backward in setting on foot exploratory travels into the immense districts to the west of the Mississippi: to these enterprizes they seem to have been particularly directed and stimulated by the acquisition of Louisiana from France, a country "rich and varied in its soil, almost inexhaustible in natural resources, and almost indefinite in extent."
