A Portrait of the Artist as a Young Man Part 5, Section 4 (pg. 270-276)
The last seven pages of the book are from Stephen's diary, meaning that the book has completed a movement from third-person to first-person narration, as if Stephen has finally seized control of his own story. The first entry tells of the conversation he just had with Cranly; other entries include comments on people he's observed, descriptions of dreams, and lots of musing about Emma. Stephen's feelings seem to be swinging all over the place. Finally, he makes it clear that he's feeling the allure of new lands and that he will soon leave Dublin. Stephen is ready for this adventure.
