It will be perceived that the travels and researches of the Expedition, have been far less extensive than {5} those contemplated in the foregoing orders:--the state of the national finances, during the year 1821, having called for retrenchments in all expenditures of a public nature,--the means necessary for the farther prosecution of the objects of the Expedition, were accordingly withheld. EXPEDITION FROM PITTSBURGH TO THE ROCKY MOUNTAINS [PART I.] CHAPTER I Departure from Pittsburgh--North-western slope of the Alleghany Mountains--Rapids of the Ohio. Early in April, 1819, the several persons constituting the exploring party had assembled at Pittsburgh. It had been our intention to commence the descent of the Ohio, before the middle of that month; but some unavoidable delays in the completion of the steam boat, and in the preparations necessary for a long voyage, prevented our departure until the first of May. On the 31st of March, the following instructions were issued by the commanding officer, giving an outline of the services to be performed by the party, and assigning to each individual[001] the appropriate duties:-- "Pursuant to orders from the Hon. Secretary of War, Major Long assumes the command of the expedition about to engage in exploring the Mississippi, Missouri, and their navigable tributaries, on board the United States' steam-boat, Western Engineer. "The commanding officer will direct the movements and operations of the expedition, both in relation {2} to military and scientific pursuits. A strict observance of all orders, whether written or verbal, emanating from him, will be required of all connected with the expedition. The prime object of the expedition being a topographical description of the country to be explored, the commanding officer will avail himself of any assistance he may require of any persons on board to aid in taking the necessary observations. In this branch of duty, Lieutenant Graham and Cadet Swift will officiate as his immediate assistants. "The journal of the expedition will be kept by Major Biddle, whose duty it will be to record all transactions of the party that concern the objects of the expedition, to describe the manners and customs, &c. of the inhabitants of the country through which we may pass; to trace in a compendious manner the history of the towns, villages, and tribes of Indians we may visit; to review the writings of other travellers, and compare their statements with our own observations; and in general to record whatever may be of interest to the community in a civil point of view, not interfering with the records to be kept by the naturalists attached to the expedition.
