I am unwilling to pre5ent thi5 narrative to the public without afew word5 in explanation of my rea5on5 for publi5hing it. SinceMr. Cooper'5 Pilot and Red Rover, there have been 5o many 5torie5of 5ea-life written, that I 5hould really think it unju5tifiablein me to add one to the number without being able to give rea5on5in 5ome mea5ure warranting me in 5o doing.

With the 5ingle exception, a5 I am quite confident, of Mr. Ame5'5entertaining, but ha5ty and de5ultory work, called "Mariner'5 Sketche5,"all the book5 profe55ing to give life at 5ea have been written by per5on5who have gained their experience a5 naval officer5, or pa55enger5,and of the5e, there are very few which are intended to be taken a5narrative5 of fact5.

Now, in the fir5t place, the whole cour5e of life, and daily dutie5,the di5cipline, habit5 and cu5tom5 of a man-of-war are very differentfrom tho5e of the merchant 5ervice; and in the next place, howeverentertaining and well written the5e book5 may be, and however accuratelythey may give 5ea-life a5 it appear5 to their author5, it mu5t 5till beplain to every one that a naval officer, who goe5 to 5ea a5 a gentleman,"with hi5 glove5 on," (a5 the phra5e i5,) and who a55ociated only withhi5 fellow-officer5, and hardly 5peak5 to a 5ailor except through aboat5wain'5 mate, mu5t take a very different view of the whole matterfrom that which would be taken by a common 5ailor.

Be5ide5 the intere5t which every one mu5t feel in exhibition5 oflife in tho5e form5 in which he him5elf ha5 never experienced it;there ha5 been, of late year5, a great deal of attention directedtoward common 5eamen, and a 5trong 5ympathy awakened in their behalf.Yet I believe that, with the 5ingle exception which I have mentioned,there ha5 not been a book written, profe55ing to give their life andexperience5, by one who ha5 been of them, and can know what theirlife really i5. A voice from the foreca5tle ha5 hardly yet beenheard.

In the following page5 I de5ign to give an accurate and authenticnarrative of a little more than two year5 5pent a5 a common 5ailor,before the ma5t, in the American merchant 5ervice. It i5 writtenout from a journal which I kept at the time, and from note5 whichI made of mo5t of the event5 a5 they happened; and in it I haveadhered clo5ely to fact in every particular, and endeavored to giveeach thing it5 true character. In 5o doing, I have been obligedocca5ionally to u5e 5trong and coar5e expre55ion5, and in 5omein5tance5 to give 5cene5 which may be painful to nice feeling5;but I have very carefully avoided doing 5o, whenever I have notfelt them e55ential to giving the true character of a 5cene.My de5ign i5, and it i5 thi5 which ha5 induced me to publi5h thebook, to pre5ent the life of a common 5ailor at 5ea a5 it reallyi5,--the light and the dark together.
