Under the head of animal history, that of the mammoth is particularly recommended to your inquiries, as it is also to learn whether the Lama or Paca of Peru, is found in those parts of this continent, or how far north they come.

The method of preserving your observations is left to yourself, according to the means which shall be in your power. It is only suggested that the noting them on the skin might be best for such as may be the most important, and that further details may be committed to the bark of the paper-birch, a substance which may not excite suspicions among the Indians, and little liable to injury from wet or other common accidents. By the means of the same substance you may perhaps find opportunities, from time to time, of communicating to the society information of your progress, and of the particulars you shall have noted.

When you shall have reached the Pacific ocean, if you find yourself within convenient distance of any settlement of Europeans, go to them, commit to writing a narrative of your journey and observations, and take the best measure you can for conveying it thence to the society by sea.

Return by the same, or some other route, as you shall think likely to fulfil with most satisfaction and certainty the objects of your mission, furnishing yourself with the best proofs the nature of the case will admit of the reality and extent of your progress. Whether this shall be by certificates from Europeans settled on the western coast of America, or by what other means, must depend on circumstances. Ignorance of the country through which you are to pass, and confidence in your judgment, zeal, and discretion, prevent the society from attempting more minute instructions, and even from exacting rigorous observance of those already given, except, indeed, what is the first of all objects, that you seek for and pursue that route which shall form the shortest and most convenient communication between the higher parts of the Missouri and the Pacific ocean.

It is strongly recommended to you to expose yourself in no case to unnecessary dangers, whether such as might affect your health or your personal safety, and to consider this not merely as your personal concern, but as the injunction of science in general, which expects its enlargement from your inquiries, and of the inhabitants of the United States in particular, to whom your report will open new fields and subjects of commerce, intercourse, and observation.

If you reach the Pacific ocean and return, the society assign to you all the benefits of the subscription before mentioned. If you reach the waters only which run into that ocean, the society reserve to themselves the apportionment of the reward according to the conditions expressed in the subscription. If you do not reach even those waters they refuse all reward, and reclaim the money you may have received here under the subscription.

They will expect you to return to the city of Philadelphia to give in to them a full narrative of your journey and observations, and to answer the inquiries they shall make of you, still reserving to yourself the benefit arising from the publication of such parts of them as are in the said subscription reserved to you.

Memorandum relative to commissioners for laying off the federal city. March 11th, 1793.

Question 1st.—What sacrifice may be made to retain Mr. Johnson in the office of commissioner for the federal territory?

Answer.—For such an object, it is worth while to give up the plan of an allowance per diem; to give, instead of that, a sum in gross, and to extend that sum to five hundred dollars per annum, and expenses; the latter to be rendered in account.
