In the following pages we hope to have contributed something towards a more thorough acquaintance with the Aborigines of our country. In other parts of our narrative where this interesting topic could not be introduced, we have turned our attention towards the phenomena of nature, to the varied and beautiful productions of animal and vegetable life, and to the more magnificent if less attractive features of the inorganic creation.
{ 2} If in this attempt we have failed to produce any thing to amuse or instruct, the deficiency is in ourselves. The few minute descriptions of animals and plants that were thought admissible, have been placed as marginal notes, and we hope they will not be the less acceptable to the scientific reader, for being given in the order in which they occurred to our notice.
Descriptions of the greater number of the animals and plants collected on the Expedition, remain to be given. These may be expected to appear from time to time, either in periodical journals or in some other form.
Not aspiring to be considered historians of the regions we traversed, we only aimed at giving a sketch true at the moment of our visit, and which, as far as it embraces the permanent features of nature, will we trust, be corroborated by those who shall follow our steps. Much remains to be done not only on the ground we have occupied, but in those vast regions in the interior of our continent, to which the foot of civilized man has never penetrated. We cannot but hope, that the enlightened spirit which has already evinced itself in directing a part of the energies of the nation, towards the development of the physical resources of our country, will be allowed still farther to operate; that the time will arrive, when we shall no longer be indebted to the men of foreign countries, for a knowledge of any of the products of our own soil, or for our opinions in science.
We feel it a duty incumbent upon us, to acknowledge our obligations to many distinguished individuals, both { 3} military and scientific, and particularly to several members of the Philosophical Society at Philadelphia, for their prompt offers of any aid in their power to contribute towards advancing the objects of the expedition at its commencement. We are indebted more especially to Professors James, Walsh, and Patterson, to Dr. Dewees and Mr. Duponceau; each of whom furnished a number of queries, and a list of objects, by which to direct our observations. These we found eminently useful, and we regret to state that, with many of our manuscripts they were inadvertently mislaid, otherwise, they should have been published in this place, for the information of future travellers.
