"We were now about to launch upon an unknown region — our route lay henceforth across that unexplored wilderness, of which I have so frequently spoken, without either pilot or trail to guide us for nearly 500 miles. We had to depend entirely upon our knowledge of the geographical position of the country for which we were steering, and the indications of a compass and sextant. This was emphatically a pioneer trip; such a one also as had, perhaps, never before been undertaken — to convey heavily laden wagons through a country almost wholly untrod by civilized man, and of which we, at least, knew nothing. We were therefore extremely anxious to acquire any information our visitors might be able to give us; but Tabba-quena being by no means experienced in wagon tactics, could only make us understand, by gestures, mixed with a little wretched Spanish, that the route up the Canadian presented no obstacles according to his mode of traveling. He appeared, however, very well acquainted with the whole Mexican frontier, from Santa Fé to Chihuahua, and even to the Gulf, as well as with all the Prairies. During the consultation he seemed occasionally to ask the opinions of other chiefs who had huddled around him. Finally, we handed him a sheet of paper and a pencil, signifying at the same time a desire that he would draw us a map of the Prairies. This he very promptly executed; and although the draft was somewhat rough, it bore, much to our astonishment, quite a map-like appearance, with a far more accurate delineation of all the principal rivers of the plains — the road from Missouri to Santa Fé, and the different Mexican settlements, than is to be found in many of the engraved maps of those regions."
