Mrs. Audubon says: '"Nothing is heard but the steady movement of the pen; your father is up and at work before dawn, and writes without ceasing all day."
When the first volume was finished, Audubon offered it to two publishers, both of whom refused it, so he published it himself in March, 1831.
In April on his way to London he travelled "on that Extraordinary road called the railway, at the rate of twenty-four miles an hour."
The first volume of his bird pictures was completed this summer, and, in bringing it out, forty thousand dollars had passed through his hands. It had taken four years to bring that volume before the world, during which time no less than fifty of his subscribers, representing the sum of fifty-six thousand dollars, had abandoned him, so that at the end of that time, he had only one hundred and thirty names standing on his list.
