We have at last entered the Atlantic Ocean this morning and with a propitious breeze; the land birds have left us, and I--I leave my beloved America, my wife, my children, my friends. The purpose of this voyage is to visit not only England, but the continent of Europe, with the intention of publishing my work on the "Birds of America." If not sadly disappointed my return to these shores, these happy shores, will be the brightest day I have ever enjoyed. Oh! wife, children, friends, America, farewell! farewell! _July 9._ _At sea._ My leaving America had for some time the feelings of a dream; I could scarce make up my mind fixedly on the subject. I thought continually I still saw my beloved friends, and my dear wife and children. I still felt every morning when I awoke that the land of America was beneath me, and that I would in a short time throw myself on the ground in her shady woods, and watch for, and listen to the many lovely warblers. But now that I have positively been at sea since _fifty-one_ days, tossing to and fro, without the sight or the touch of those dear to me, I feel fully convinced, and look forward with an anxiety such as I never felt before, when I calculate that not less than four months, the third of a year, must elapse before my wife and children can receive any tidings of my arrival on the distant shores to which I am bound. When I think that many more months must run from the Life's sand-glass allotted to my existence before I can think of returning, and that my re-union with my friends and country is yet an unfolded and unknown event, I am filled with sudden apprehensions which I cannot describe nor dispel.
