It was at this time that Astor founded Astoria as a fur trading point, on the Columbia River, expecting to operate by ship, as well as freighting overland by the way of Ft. Laramie, and thus control the fur traffic along the tributary rivers. The destruction of Astoria by the British kept him from realizing his dream of becoming "the richest man in the world." Washington Irving and John Jacob Astor were friends, and the latter placed in Irving's hands all the records of his Company's operations, from which Irving gathered much interesting data, and many thrilling experiences from the lives of the early trappers and hunters. He wrote "Astoria" as a compliment to his friend. In this book he pictures the Rocky Mountains as having an elevation in places of twenty-five thousand feet, but frankly states that it is only conjecture, since their altitude had never been measured. The average height of the Rocky Mountains exceed that of the famous Alps, a number of the noted peaks being above thirteen thousand feet. Some of Irving's interesting and pleasing prophecies of our country follow: "It is a region almost as vast and trackless as the ocean, and at the time of which we treat, but little known, excepting through the vague accounts of Indian hunters. A part of their route would lay across an immense tract, stretching North and South for hundreds of miles along the foot of the Rocky Mountains, and drained by the tributaries of the Missouri and the Mississippi. This region, which resembles one of the immeasurable steppes of Asia, has not inaptly been termed 'The Great American Desert.' It spreads forth into undulating and trackless plains and desolate sandy wastes, wearisome to the eye from their extent and monotony, and which are supposed by geologists to have formed the ancient floor of the ocean, countless ages since, when its primeval waves beat against the granite bases of the Rocky Mountains.
