Could we have thrown into vivid forms a few only of the numberless incidents of rare beauty which thronged our path--could we have imparted to pages that freshness and glow, which invested the institutions of freedom, just bursting into bloom over the late wastes of slavery--could we, in fine, have carried our readers amid the scenes which we witnessed, and the sounds which we heard, and the things which we handled, we should not doubt the power and permanence of the impression produced.

It is due to the cause, and to the society under whose commission we acted, frankly to state, that we were not selected on account of any peculiar qualifications for the work.

As both of us were invalids, and compelled to fly from the rigors of an American winter, it was believed that we might combine the improvement of health, with the prosecution of important investigations, while abler men could thus be retained in the field at home; but we found that the unexpected abundance of materials requires the strongest health and powers of endurance.

We regret to add, that the continued ill health of both of us, since our return, so serious in the case of one, as to deprive him almost wholly of participation in the preparation of the work, has necessarily, delayed its appearance, and rendered its execution more imperfect.
We lay no claim to literary merit.

To present as simple narrative of facts, has been our sole aim.
