enetrate a short distance among the mountains。〃
Next day the party found themselves in clover； so to speak。 Game was plenty； and； as their object now was to accumulate meat for the three men who were to be left at the falls （and who were not hunters）； they resolved to strike the Medicine； or Sun； River and hunt down its banks。 On that river the journal； July 10； has this to say：
〃In the plains are great quantities of two species of prickly…pear now in bloom。 Gooseberries of the common red kind are in abundance and just beginning to ripen； but there are no currants。 The river has now widened to one hundred yards； it is deep； crowded with islands； and in many parts rapid。 At the distance of seventeen miles； the timber disappears totally from the river…bottoms。 About this part of the river； the wind； which had blown on our backs； and constantly put the elk on their guard； shifted round； we then shot three of them and a brown bear。 Captain Lewis halted to skin them； while two of the men took the pack…horses forward to seek for a camp。 It was nine o'clock before he overtook them； at the distance of seven miles； in the first grove of cottonwood。 They had been pursued as they came along by a very large bear； on which they were afraid to fire； lest their horses； being unaccustomed to the gun； might take fright and throw them。 This circumstance reminds us of the ferocity of these animals； when we were last near this place； and admonishes us to be very cautious。 We saw vast numbers of buffalo below us； which kept up a dreadful bellowing during the night。 With all our exertions we were unable to advance more than twenty…four miles； owing to the mire through which we are obliged to travel； in consequence of the rain。〃
The Sun； or Medicine； River empties into the Missouri just above the great falls of that stream； and near here； opposite White Bear Islands； the expedition had deposited some of their property in a cache dug near the river bank； when they passed that way； a year before。 On the thirteenth of the month； having reached their old camping…ground here； the party set to work making boat…gear and preparing to leave their comrades in camp well fixed for their stay。 The journal adds：
〃On opening the cache； we found the bearskins entirely destroyed by the water； which in a flood of the river had penetrated to them。 All the specimens of plants； too； were unfortunately lost： the chart of the Missouri； however； still remained unhurt； and several articles contained in trunks and boxes had suffered but little injury； but a vial of laudanum had lost its stopper； and the liquid had run into a drawer of medicines； which it spoiled beyond recovery。 The mosquitoes were so troublesome that it was impossible even to write without a mosquito bier。 The buffalo were leaving us fast； on their way to the southeast。〃
One of the party met with an amusing adventure here； which is thus described：
〃At night M'Neal； who had been sent in the morning to examine the cache at the lower end of the portage； returned； but had been prevented from reaching that place by a singular adventure。 Just as he arrived near Willow run； he approached a thicket of brush in which was a white bear； which he did not discover till he was within ten feet of him。 His horse started； and wheeling suddenly round； threw M'Neal almost immediately under the bear； which started up instantly。 Finding the bear raising himself on his hind feet to attack him； he struck him on the head with the butt end of his musket； the blow was so violent that it broke the breech of the musket and knocked the bear to the ground。 Before he recovered M'Neal； seeing a willow…tree close by； sprang up； and there remained while the bear closely guarded the foot of the tree until late in the afternoon。 He then went off； M'Neal being released came down； and having found his horse； which had strayed off to the distance of two miles； returned to camp。 These animals are； indeed； of a most extraordinary ferocity； and it is matter of wonder that in all our encounters we have had the good fortune to escape。 We are now troubled with another enemy； not quite so dangerous； though even more disagreeable…these are the mosquitoes； who now infest us in such myriads that we frequently get them into our throats when breathing； and the dog even howls with the torture they occasion。〃
The intention of Captain Lewis was to reach the river sometimes known as Maria's； and sometimes as Marais； or swamp。 This stream rises near the boundary between Montana and the British possessions； and flows into the Missouri； where the modern town of Ophir is built。 The men left at the great falls were to dig up the canoes and baggage that had been cached there the previous year； and be ready to carry around the portage of the falls the stuff that would be brought from the two forks of the Jefferson； later on； by Sergeant Ordway and his party。 It will be recollected that this stuff had also been cached at the forks of the Jefferson； the year before。 The two parties； thus united； were to go down to the entrance of Maria's River into the Missouri； and Captain Lewis expected to join them there by the fifth of August； if he failed to meet them by that time； they were to go on down the river and meet Captain Clark at the mouth of the Yellowstone。 This explanation is needed to the proper understanding of the narrative that follows； for we now have to keep track of three parties of the explorers。
Captain Lewis and his men； having travelled northwest about twenty miles from the great falls of the Missouri； struck the trail of a wounded buffalo。 They were dismayed by the sight； for that assured them that there were Indians in the vicinity； and the most natural thing to expect was that these were Blackfeet； or Minnetarees； both of these tribes are vicious and rascally people； and they would not hesitate to attack a small party and rob them of their guns； if they thought themselves able to get away with them。
They were now in the midst of vast herds of buffalo； so numerous that the whole number seemed one immense herd。 Hanging on the flanks were many wolves； hares and antelope were also abundant。 On the fourth day out； Captain Lewis struck the north fork of Maria's River； now known as Cut…bank River； in the northwest corner of Montana。 He was desirous of following up the stream； to ascertain； if possible； whether its fountain…head was below； or above； the boundary between the United States and the British possessions。 Bad weather and an accident to his chronometer prevented his accomplishing his purpose； and； on the twenty…sixth of July； he turned reluctantly back； giving the name of Cape Disappointment to his last camping…place。 Later in that day； as they were travelling down the main stream （Maria's River）； they encountered the Indians whom they had hoped to avoid。 Let us read the story as it is told in the journal of the party：
〃At the distance of three miles we ascended the hills close to the river…side； while Drewyer pursued the valley of the river on the opposite side。 But scarcely had Captain Lewis reached the high plain when he saw； about a mile on his left； a collection of about thirty horses。 He immediately halted； and by the aid of his spy…glass discovered that one…half of the horses were saddled； and that on the eminence above the horses several Indians were looking down toward the river； probably at Drewyer。 This was a most unwelcome sight。 Their probable numbers rendered any contest with them of doubtful issue； to attempt to escape would only invite pursuit； and our horses were so bad that we must certainly be overtaken； besides which； Drewyer could not yet be aware that the Indians were near； and if we ran be would most probably be sacrificed。 We therefore determined to make the most of our situation； and advance toward them in a friendly manner。 The flag which we had brought in case of any such accident was therefore displayed； and we continued slowly our march toward them。 Their whole attention was so engaged by Drewyer that they did not immediately discover us。 As soon as they did see us； they appeared to be much alarmed and ran about in confusion； some of them came down the hill and drove their horses within gunshot of the eminence； to which they then returned； as if to await our arrival。 When we came within a quarter of a mile； one of the Indians mounted and rode at full speed to receive us； but when within a hundred paces of us； he halted。 Captain Lewis； who had alighted to receive him； held out his hand and beckoned to him to approach； he only looked at us for some time； and then； without saying a word； returned to his companions with as much baste as be had advanced。 The whole party now descended the hill and rode toward us。 As yet we saw only eight； but presumed that there must be more behind us； as there were several horses saddled。 We however advanced； and Captain Lewis now told his two men that he believed these were the Minnetarees of Fort de Prairie； who； from their infamous character； would in all probability attempt to rob us； but being determined to die rather than lose his papers and instruments； he intended to resist to the last extremity； and advised them to do the same； and to be on the alert should there be any disposition to attack us。 When the two parties came within a hundred yards of each other； all the Indians； except one； halted。 Captain Lewis therefore ordered his two men to halt while be advanced； and after shaking hands with the Indian； went on and did the same with the others in the rear； while the Indian himself shook hands with the two men。 They all now came up； and after alighting； the Indians asked to smoke with us。 Captain Lewis； who was very anxious for Drewyer's safety； told them that the man who had gone down the river had the pipe； and requested that as they had seen him； one of them would accompany R。 Fields； to bring him back。 To this they assented； and Fields went with a young man in search of Drewyer。〃
Captain Lewis now asked them by signs if they were Minnetarees of the north； and he was sorry to be told in reply that they were； he knew them to be a bad lot。 When asked if they had any chief among them； they pointed out three。 The captain did not believe them；
