A Vision of Frost


Clark woke to a frost-bound landscape that evoked a somewhat lyrical description.

Many Visitors to Camp


The camp was visited by a group of French settlers from Portage des Sioux, and other local inhabitants. On the same day a letter was sent from a senior official of Louisiana, perhaps the Governor, instructing the regional commander to hand over his post to an American agent, and to allow the Expedition free passage on the Missouri.

Letter

If upon the receipt of this Your Excellency finds himself commanding that post, without someone having presented himself, who would take charge in behalf of the United States, which took possession of this capital and province the 20th of December last: you will not put any obstacle to impede Capt. Merry Weather Lewis’ entrance in the Missouri whenever he wishes; nevertheless Your Excellency did right in taking the dispositions of which your official letter no. 213 treats; since you had no orders from your government.

Your Excellency should try to conform at the capital to the terms which have been prescribed to you by our order, which you should have received in duplicate, as soon as you will deliver your posts to the official or agent of the United States, who will present himself to that purpose.

God keep Your Excellency many years.

Another Beautiful Frosty Morning


In two entries on separate sheets, Clark recorded another fine ice spectacle, and took a very cold early morning temperature reading before going up river with Lewis. He had now been ill since the 10th January, and would not recover until the 6th February.

From January 1804 onwards, the two leaders of the expedition kept a weather log independently of their other journals. In January 1804, Lewis began a weather diary in which Clark wrote most of the entries while Lewis was in St. Louis. Clark also kept a copy of these entries in another notebook. The weather diaries, which closely parallel information given in the regular journals, can be read in Moulton, where they follow the journal entries for each month.
