Great as was Audubon's wish to proceed without delay to Louisiana, he felt it due to his subscribers to get to work at once, and wrote to his wife under date of New York, May 10, 1829: "I have landed here from on board the packet ship Columbia after an agreeable passage of thirty-five days from Portsmouth. I have come to America to remain as long as consistent with the safety of the continuation of my publication in London without my personal presence. According to future circumstances I shall return to England on the 1st of October next, or, if possible, not until April, 1830. I wish to employ and devote every moment of my sojourn in America to drawing such birds and plants as I think necessary to enable me to give my publication throughout the degree of perfection that I am told exists in that portion already published. I have left my business going on quite well; my engraver[40] has in his hands all the drawings wanted to complete this present year, and those necessary to form the first number of next year. I have finished the two first years of publication, the two most difficult years to be encountered." To Victor he writes from Camden, N.J., July 10, 1829: "I shall this year have issued ten numbers, each containing five plates, making in all fifty.[41] I cannot publish more than five numbers annually, because it would make too heavy an expense to my subscribers, and indeed require more workmen than I could find in London. The work when finished will contain eighty numbers,[42] therefore I have seventy to issue, which will take fourteen years more. It is a long time to look forward to, but it cannot be helped. I think I am doing well; I have now one hundred and forty-four subscribers." All this summer and early fall, until October 10th, Audubon spent in the neighborhood of New Jersey and Pennsylvania, working as few can work, four hours continuing to be his allowance for sleep. Six weeks in September and October were spent in the Great Pine Swamp, or Forest,[43] as he called it, his permanent lodgings being at Camden, N.J. Here he writes, October 11, 1829: "I am at work and have done much, but I wish I had eight pairs of hands, and another body to shoot the specimens; still I am delighted at what I have accumulated in drawings this season. Forty-two drawings in four months, eleven large, eleven middle size, and twenty-two small, comprising ninety-five birds, from Eagles downwards, with plants, nests, flowers, and sixty different kinds of eggs. I live alone, see scarcely any one, besides those belonging to the house where I lodge. I rise long before day and work till nightfall, when I take a walk, and to bed. "I returned yesterday from Mauch Chunk; after all, there is nothing perfect but _primitiveness_, and my efforts at copying nature, like all other things attempted by us poor mortals, fall far short of the originals. Few better than myself can appreciate this with more despondency than I do."
