In the summer of 1832, Audubon, accompanied by his wife and two sons, made a trip to Maine and New Brunswick, going very leisurely by private conveyance through these countries, studying the birds, the people, the scenery, and gathering new material for his work. His diaries give minute accounts of these journeyings. He was impressed by the sobriety of the people of Maine; they seem to have had a "Maine law" at that early date; "for on asking for brandy, rum, or whiskey, not a drop could I obtain." He saw much of the lumbermen and was a deeply interested spectator of their ways and doings. Some of his best descriptive passages are contained in these diaries. In October he is back in Boston planning a trip to Labrador, and intent on adding more material to his "Birds" by another year in his home country. That his interests abroad in the meantime might not suffer by being entirely in outside hands, he sent his son Victor, now a young man of considerable business experience, to England to represent him there. The winter of 1832 and 1833 Audubon seems to have spent mainly in Boston, drawing and re-drawing and there he had his first serious illness. In the spring of 1833, a schooner was chartered and, accompanied by five young men, his youngest son, John Woodhouse, among them, Audubon started on his Labrador trip, which lasted till the end of summer. It was an expensive and arduous trip, but was greatly enjoyed by all hands, and was fruitful in new material for his work. Seventy-three bird skins were prepared, many drawings made, and many new plants collected. The weather in Labrador was for the most part rainy, foggy, cold, and windy, and his drawings were made in the cabin of his vessel, often under great difficulties. He makes this interesting observation upon the Eider duck: "In one nest of the Eider ten eggs were found; this is the most we have seen as yet in any one nest. The female draws the down from her abdomen as far toward her breast as her bill will allow her to do, but the feathers are not pulled, and on examination of several specimens, I found these well and regularly planted, and cleaned from their original down, as a forest of trees is cleared of its undergrowth. In this state the female is still well clothed, and little or no difference can be seen in the plumage, unless examined."
