In the spring of 1828 Audubon began to think of returning to the United States, to renew or revise his drawings and extend his researches. "I am sure," he said, "that now I could make better compositions, and select better plants than when I drew mainly for amusement." In order to raise the necessary funds, he resorted again to picture painting, his never failing resource, and worked in oil colors daily from morning light until dusk, unless called to Havell's to decide some question of necessary detail. The following letters to Swainson shed further light on this work and on the progress of The Birds of America, the eighth number of which was published early in July:

Audubon to William Swainson

London, July 1st 1828.

My dear Sir.—

I have been expecting to have the pleasure of seeing you for upwards of a week, having mentioned in your last note that you intended spending a couple of days in London before the end of June.—When are you coming?—the beautifull lamb came quite safe and is now on the canvas (in efigy) for ages to come—I bought a superb Golden Eagle from Mr. Cross that also has helped to fill it —— [Here apparently some words have been deleted, and it is impossible to read them.] I long to shew them to you.—I have finished the picture of the Turkeys, and painted a white headed eagle—in fact I have worked from 4 every morning untill dark—but the best news I have to tell is; that I have received 4 letters from my wife, one dated 2nd of May, all well—but not quite settled about coming before the end of summer. I have changed quarters and am now at 79 Newman Street Oxford Street, in Mr. Havell's house where I have taken 3 rooms and feel more comfortable although I have not the little piece of ground to walk on.—I imagine the country to be now quite beautifull and had I time to spare would walk out to see you Mrs S & the dear little folks at Tittenhanger Green.—I received a visit on Saturday last of the whole of Lord Milton's family who after complimenting the author of the "Birds of America" very kindly subscribed for two copies of the work.—I have mended my pen—I should have sent the Blackwood magazine to you, but I so much expected to see you here that it is yet on my table, and will keep it untill you come.—All my exertions to procure live grouses have been abortive here—I have written to Scotland to a friend and perhaps will have some soon.—The 8th number is now printing and colouring and will be out this month—the 9th is began.—If you are hungry or thirsty when you come to town please make for my [here a word is omitted], and I will try to manage matters in this way.—May I ask what you are doing?—I saw Dr Fraill's [Traill's] son a few days ago—he inquired after your son and family.—I expect a copy of Loudon's magazine this evening. I feel anxious to see what sort of a cut the Doves make, as well as the birds of Washington.—

With sincerest regards & esteem to yourself and Lady—

I am yours most truly
John J. Audubon.

79 Newman Street,
Oxford Street.
