In all our marches we observed the following order. Capt. Bell, mounted on a horse whose gait was regular and uniform, and well calculated for the estimation of distances, preceded the party, attended by our guide.—The soldiers and attendants, formed into two squads, for the better management of the pack-horses, followed in single file.—The scientific gentlemen occupied any part of the line that best suited their convenience.—Major Long followed in the rear, for the purpose of superintending the readjustment of deranged packs, and urging any disposed to linger, to the observance of a close order of march, a duty attended with no inconsiderable trouble and perplexity. Though our route lay at the distance of several miles from the Platte, we could distinctly see the narrow and interrupted line of timber which grows along its course, and occasionally we had a transient view of the river itself, spreading like an expansive lake, and embosoming innumerable islands. About eighteen miles from our encampment, our course led us into the valley of a small river, called La petite Coquille or Muscleshell Creek,[77] which we ascended six miles, not deviating from the course we had taken. In the middle of the day we encountered a violent thunder-storm without dismounting {120} from our horses. The plain about us, for a great distance, was destitute of timber, and so level that our party formed the most prominent object in an extent of several miles. It is not surprising that, in this situation, we were a little startled at seeing the lightning strike upon the ground at the distance of two hundred yards from us. We could not have been deceived, in relation to this appearance, as we distinctly saw the water and mud thrown several feet into the air by the shock. The storm was so violent that, notwithstanding all our care, we could not prevent our baggage from being wet. We crossed the Coquille six miles above the place where it enters the valley of the Platte. This we effected with some difficulty, the banks being steep and muddy, and immediately afterwards encamped to dry our baggage. [77] See _ante_, note 40.—ED. The Coquille is about eight yards across; its bed muddy and the current moderate. Its course is circuitous, traversing some inconsiderable tracts of fertile and well wooded bottom land: in one of these our camp was placed. The night was warm and the mosquitoes swarming in inconceivable multitudes.
