On the 17th of May, the Delos put out to sea. I was immediately affected with sea-sickness, which, however, lasted but a short time. I remained on deck constantly, forcing myself to exercise.

The fact is I am growing old too fast, alas! I feel it, and yet work I will, and may God grant me life to see the last plate of my mammoth work finished.

If only the bird with the loveliest song sang, the forest would be a lonely place.

In my deepest troubles, I frequently would wrench myself from the persons around me and retire to some secluded part of our noble forests.

I wish I had eight pairs of hands, and another body to shoot the specimens.

If I can procure three hundred good substantial names of persons, or bodies, or institutions, I cannot fail to do well for my family, although I must abandon my life to its success, and undergo many sad perplexities and perhaps never see again my own beloved America.

I discover that my friends think only of my apparel, and those upon whom I have conferred acts of kindness prefer to remind me of my errors.
