f them。 Information was received that Captain Clark had arrived five miles below； at a rapid which he did not think it prudent to ascend； and that he was waiting there for the party above to rejoin him。
After the departure of Captain Lewis； Captain Clark had remained a day at Maria's River； to complete the deposit of such articles as they could dispense with； and started on the twelfth of June。
Four days later； Captain Clark left the river； having sent his messenger to Captain Lewis； and began to search for a proper portage to convey the pirogue and canoes across to the Columbia River； leaving most of the men to hunt； make wheels and draw the canoes up a creek which they named Portage Creek； as it was to be the base of their future operations。 The stream is now known as Belt Mountain Creek。 But the explorers soon found that although the pirogue was to be left behind； the way was too difficult for a portage even for canoes。 The journal says：
〃We found great difficulty and some danger in even ascending the creek thus far； in consequence of the rapids and rocks of the channel of the creek； which just above where we brought the canoes has a fall of five feet； with high steep bluffs beyond it。 We were very fortunate in finding； just below Portage Creek； a cottonwood tree about twenty…two inches in diameter； large enough to make the carriage…wheels。 It was； perhaps； the only one of the same size within twenty miles； and the cottonwood which we are obliged to employ in the other parts of the work is extremely soft and brittle。 The mast of the white pirogue； which we mean to leave behind； supplied us with two axle…trees。
〃There are vast quantities of buffalo feeding on the plains or watering in the river； which is also strewed with the floating carcasses and limbs of these animals。 They go in large herds to water about the falls； and as all the passages to the river near that place are narrow and steep； the foremost are pressed into the river by the impatience of those behind。 In this way we have seen ten or a dozen disappear over the falls in a few minutes。 They afford excellent food for the wolves； bears； and birds of prey； which circumstance may account for the reluctance of the bears to yield their dominion over the neighborhood。
〃The pirogue was drawn up a little below our camp； and secured in a thick copse of willow…bushes。 We now began to form a cache or place of deposit； and to dry our goods and other articles which required inspection。 The wagons are completed。 Our hunters brought us ten deer； and we shot two out of a herd of buffalo that came to water at Sulphur Spring。 There is a species of gooseberry； growing abundantly among the rocks on the sides of the cliffs。 It is now ripe； of a pale red color； about the size of the common gooseberry； and like it is an ovate pericarp of soft pulp enveloping a number of small whitish seeds； and consisting of a yellowish； slimy； mucilaginous substance； with a sweet taste； the surface of the berry is covered glutinous； adhesive matter； and its fruit； though ripe； retains its withered corolla。 The shrub itself seldom rises more than two feet high； is much branched； and has no thorns。 The leaves resemble those of the common gooseberry； except in being smaller； and the berry is supported by separate peduncles or foot…stalks half an inch long。 There are also immense quantities of grasshoppers； of a brown color； on the plains； they； no doubt； contribute to the lowness of the grass； which is not generally more than three inches high； though it is soft； narrow…leaved； and affords a fine pasture for the buffalo。〃
Chapter XI
A the Heart of the Continent
Captain Clark continued his observations up the long series of rapids and falls until he came to a group of three small islands to which he gave the name of White Bear Islands； from his having seen numerous white； or grizzly； bears on them。 On the nineteenth of June； Captain Clark； after a careful survey of the country on both sides of the stream； decided that the best place for a portage was on the south； or lower； side of the river； the length of the portage being estimated to be about eighteen miles； over which the canoes and supplies must be carried。 Next day he proceeded to mark out the exact route of the portage； or carry； by driving stakes along its lines and angles。 From the survey and drawing which he made； the party now had a clear and accurate view of the falls； cascades； and rapids of the Missouri； and； it may be added； this draught； which is reproduced on another page of this book； is still so correct in all its measurements that when a Montana manufacturing company undertook to build a dam at Black Eagle Falls； nearly one hundred years afterwards； they discovered that their surveys and those of Captain Clark were precisely alike。 The total fall of the river； from the White Bear Islands； as Lewis and Clark called them； to the foot of the Great Falls； is four hundred twelve and five…tenths feet； the sheer drop of the Great Fall is seventy…five and five…tenths feet。 The wild； trackless prairie of Lewis and Clark's time is now the site of the thriving town of Great Falls； which has a population of ten thousand。
Here is a lucid and connected account of the falls and rapids； discovered and described by Lewis and Clark：
〃This river is three hundred yards wide at the point where it receives the waters of Medicine ＇Sun＇ River； which is one hundred and thirty…seven yards in width。 The united current continues three hundred and twenty…eight poles to a small rapid on the north side； from which it gradually widens to fourteen hundred yards； and at the distance of five hundred and forty…eight poles reaches the head of the rapids； narrowing as it approaches them。 Here the hills on the north； which had withdrawn from the bank； closely border the river； which； for the space of three hundred and twenty poles； makes its way over the rocks； with a descent of thirty feet。 In this course the current is contracted to five hundred and eighty yards； and after throwing itself over a small pitch of five feet； forms a beautiful cascade of twenty…six feet five inches； this does not； however； fall immediately or perpendicularly； being stopped by a part of the rock； which projects at about one…third of the distance。 After descending this fall； and passing the cottonwood island on which the eagle has fixed her nest； the river goes on for five hundred and thirty…two poles over rapids and little falls； the estimated descent of which is thirteen and one…half feet； till it is joined by a large fountain boiling up underneath the rocks near the edge of the river； into which it falls with a cascade of eight feet。 The water of this fountain is of the most perfect clearness； and of rather a bluish cast； and； even after falling into the Missouri； it preserves its color for half a mile。 From the fountain the river descends with increased rapidity for the distance of two hundred and fourteen poles； during which the estimated descent is five feet； and from this； for a distance of one hundred and thirty…five poles； it descends fourteen feet seven inches； including a perpendicular fall of six feet seven inches。 The Missouri has now becom
