This morning early we employed all hands; some were making tar or attempting to make it, others were attatching the skins on the boat, other cuting and fiting the bark for lining puting in the woodworke &c some hunters  were sent out to kill buffaloe in order to make pemecon to take with us and also for their skins which we now wa[n]t to cover our baggage in the boat and canoes when we depart from hence. the Indians have informed us that we should shortly leave the buffaloe country after passing the falls; this I much regret for I know when we leave the buffaloe that we shal sometimes be under the necessity of fasting occasionally. and at all events the white puddings will be irretreivably lost and Sharbono out of imployment. our tar-kiln which ought to have began to run this morning has yealded no tar as yet and I am much affraid will not yeald any, if so I fear the whole opperation of my boat will be useless. I fear I have committed another blunder also in sewing the skins with a nedle which has sharp edges these have cut the skin and as it drys I discover that the throng dose not fill the holes as I expected tho' I made them sew with a large throng for that purpose. at 10 OCk A. M. we had a slight shower which scarcely wet the grass. One buffaloe only and 2 Antelopes killed today six beaver and 2 otter have been killed within the last three days. The current of the river looks so gentle and inviting that the men all seem anxious to be moving upward as well as ourselves. we have got the boat prety well forward today and think we shall be able to complete her tomorrow except paying her,  to do which will require some little time to make her first perfectly dry. she has assumed her shape and looks extreemly well. She will be very light, more so than any vessel of her size that I ever saw.

The water tolerably clear and Soft in the river, Current jentle and bottoms riseing from the water; no appearance of the river riseing more than a few feet above the falls, as high up as we have yet explored. but few trees on the Std Side the grass is high and fine near the river. the winds has blown for Several days from the S. W. I think it possible that those almost perpetial S W. winds, proceed from the agency of the Snowey mountains and the wide leavel and untimbered plains which Streach themselves along their borders for an emence distance, that the air comeing in Contact with the Snow is Suddenly chilled and condensed, thus becomeing heavyer than the air beneath in the plains it glides down the Sides of those mountains and decends to the plains, where by the constant action of the Sun on the face of the untimbered country there is a partial vacuom formed for it's reception I have observed that the winds from this quarter is always the Coaldest and most violent which we experience, yet I am far from giveing full credit to this hypothesis on this Subject; if I find however on the opposit Side of these mountains that the winds take a contrary direction I Shall then have full faith. (The winds take a contrary direction in the morning or from the mountains on the west Side)

Wednesday 3rd. A fine morning. I was so engaged with the boat, that I had not visited the falls. I therefore set out with one of the men to day for that purpose. I found the 2nd pitch the most beautiful, though not the highest.  About a mile below the upper pitch,  the largest and most beautful spring  rises out of the bank of the Missouri on the south side that I ever beheld. We had a light shower of rain. During this excursion I saw more buffaloe than I had seen in any day previous: we killed 7 of them before we returned to camp. We also saw 25 wolves in one gang or pack.
