It was eight years after Pursley's pilgrimage before the trade with New Mexico attracted the attention of speculators and adventurers. Messrs. McKnight,[13] Beard, and Chambers, with about a dozen comrades, started with a supply of goods across the unknown plains, and by good luck arrived safely at Santa Fe. Once under the jurisdiction of the Mexicans, however, their trouble began. All the party were arrested as spies, their wares confiscated, and themselves incarcerated at Chihuahua, where the majority of them were kept for almost a decade. Beard and Chambers, having by some means escaped, returned to St. Louis in 1822, and, notwithstanding their dreadful experience, told of the prospects of the trade with the Mexicans in such glowing colours that they induced some individuals of small capital to fit out another expedition, with which they again set out for Santa Fe. It was really too late in the season; they succeeded, however, in reaching the crossing of the Arkansas without any difficulty, but there a violent snowstorm overtook them and they were compelled to halt, as it was impossible to proceed in the face of the blinding blizzard. On an island[14] not far from where the town of Cimarron, on the Santa Fe Railroad, is now situated, they were obliged to remain for more than three months, during which time most of their animals died for want of food and from the severe cold. When the weather had moderated sufficiently to allow them to proceed on their journey, they had no transportation for their goods and were compelled to hide them in pits dug in the earth, after the manner of the old French voyageurs in the early settlement of the continent. This method of secreting furs and valuables of every character is called caching, from the French word "to hide." Gregg thus describes it:
