The remaining three months before Audubon sailed for America, April 1, 1829, were passed in preparations for his absence from his book, and many pages of his fine, close writing are filled with memoranda for Mr. Havell, Mr. J. G. Children, and Mr. Pitois. Audubon writes: "I have made up my mind to go to America, and with much labor and some trouble have made ready. My business is as well arranged for as possible; I have given the agency of my work to my excellent friend Children, of the British Museum, who kindly offered to see to it during my absence. I have collected some money, paid all my debts, and taken my passage in the packet-ship 'Columbia,' Captain Delano. I chose the ship on account of her name, and paid thirty pounds for my passage. I am about to leave this smoky city for Portsmouth, and shall sail on April 1." The voyage was uneventful, and America was reached on May 1. Almost immediately began the search for new birds, and those not delineated already, for the continuation and completion of the "Birds of America." [Illustration: EAGLE AND LAMB.

Rathbone, of the firm of Rathbone Bros. & Co., to whom Audubon had a letter from Mr. Vincent Nolte. To Messrs. Wm. and Richard Rathbone, and their father Wm. Rathbone, Sr., Audubon was more deeply indebted than to any other of his many kind friends in England. Their hospitality was only equalled by their constant and valuable assistance in preparing for the publication of the "Birds," and when this was an assured fact, they were unresting in their efforts to aid Audubon in procuring subscribers. It is with pleasure that Audubon's descendants to-day acknowledge this indebtedness to the "family Rathbone," which is ever held in grateful remembrance.
