In the beginning of the trade with New Mexico, the route across the great plains was directly west from the Missouri River to the mountains, thence south to Santa Fe by the circuitous trail from Taos. When the traffic assumed an importance demanding a more easy line of way, the road was changed, running along the left bank of the Arkansas until that stream turned northwest, at which point it crossed the river, and continued southwest to the Raton Pass. The Atchison, Topeka, and Santa Fe Railroad track substantially follows the Trail through the mountains, which here afford the wildest and most picturesquely beautiful scenery on the continent. The Arkansas River at the fording of the Old Trail is not more than knee-deep at an ordinary stage of water, and its bottom is well paved with rounded pebbles of the primitive rock. The overland trade between the United States and the northern provinces of Mexico seems to have had no very definite origin; having been rather the result of an accident than of any organized plan of commercial establishment. According to the best authorities, a French creole, named La Lande, an agent of a merchant of Kaskaskia, Illinois, was the first American adventurer to enter into the uncertain channels of trade with the people of the ultramontane region of the centre of the continent. He began his adventurous journey across the vast wilderness, with no companions but the savages of the debatable land, in 1804; and following him the next year, James Pursley undertook the same pilgrimage. Neither of these pioneers in the "commerce of the prairies" returned to relate what incidents marked the passage of their marvellous expeditions. Pursley was so infatuated with the strange country he had travelled so far to reach, that he took up his abode in the quaint old town of Santa Fe where his subsequent life is lost sight of. La Lande, of a different mould, forgot to render an account of his mission to the merchant who had sent him there, and became a prosperous and wealthy man by means of money to which he had no right. To Captain Zebulon Pike, who afterwards was made a general, is due the impetus which the trade with Santa Fe received shortly after his return to the United States. The student of American history will remember that the expedition commanded by this soldier was inaugurated in 1806; his report of the route he had taken was the incentive for commercial speculation in the direction of trade with New Mexico, but it was so handicapped by restrictions imposed by the Mexican government, that the adventurers into the precarious traffic were not only subject to a complete confiscation of their wares, but frequently imprisoned for months as spies. Under such a condition of affairs, many of the earlier expeditions, prior to 1822, resulted in disaster, and only a limited number met with an indifferent success.
