Boswell's correspondence with Andrew Erskine opens with a tone of high-spirited literary play: the two young men trade verses, mock each other's pretensions, and adopt exaggerated personae. The letters are dense with allusions, puns, and self-conscious wit, showing Boswell rehearsing the conversational style he would later refine in his London journals. Yet when the volume turns to the Journal of a Tour to Corsica, the voice changes markedly. The prose becomes more deliberate, the sentences longer, and the observations more patient. Boswell is now a traveller reporting on a little-known island, and he writes with the earnestness of an explorer. The shift is not merely one of subject but of narrative stance: the correspondent who joked about his own vanity becomes a chronicler who weighs the reliability of his sources and notes the dangers of Barbary corsairs with a straight face.

From Epistolary Banter to Travel Narrative

The two halves of this volume differ not only in genre but in the fundamental relationship between writer and reader. In the letters to Erskine, Boswell writes to an intimate equal; he can assume shared references, indulge in inside jokes, and leave thoughts half-finished. The sentences are short, the paragraphs brisk, and the tone often flippant. By contrast, the Journal addresses a public audience. Boswell explains customs, translates phrases, and justifies his decisions—as when he chooses to land on Corsican territory rather than at French-held Bastia. The pace slows accordingly. Where the letters skip from topic to topic, the journal lingers on a single sea voyage for several pages, recording the calm, the shipboard music, and the anxiety about pirates. This shift in pace is not a flaw but a deliberate adaptation to purpose: the letters perform sociability, while the journal performs authority.

Voice as a Marker of Audience

Boswell's handling of his own persona offers a clear index of his intended audience. To Erskine, he presents himself as a young man of letters, eager to display his cleverness and secure his friend's approval. He quotes his own verses, boasts of his connections, and adopts a tone of mock-heroic self-importance. In the Journal, however, he curates a more modest and credible persona. He admits to being detained by 'the charms of sweet Siena,' but frames this as a weakness overcome by the need for 'the hardy air of Corsica.' He includes a letter of recommendation from Rousseau, but does not dwell on it. He reports the warnings of a naval officer and the skepticism of Leghorn's residents, then counters them with the assurance of Count Rivarola. The effect is to present himself as both adventurous and prudent—a narrator the reader can trust. The voice is less flamboyant, but more persuasive.

Pace and the Management of Suspense

Boswell controls narrative pace most carefully in the passages leading up to his meeting with Paoli. He builds suspense through a series of delays and obstacles: the calm at sea, the choice of landing point, the need for passports, the warnings of danger. Each paragraph adds a new layer of anticipation. When he finally writes, 'I was impatient to be with the illustrious Chief,' the reader shares the impatience. Yet Boswell does not rush. He inserts a digression on the state of Corsica, then a story about a surgeon's mate, then a discussion of Barbary corsairs. The effect is to make the eventual arrival feel earned. This technique—accumulating detail while deferring the climax—is absent from the letters, which move by association rather than design. In the Journal, Boswell has learned to use pace as a tool of narrative engagement.

Readers coming to this volume from Boswell's later Life of Johnson will recognise the same curiosity about character and the same willingness to let his subjects speak at length. But here the voice is still forming: the letters show the raw material of his sociable style, while the journal reveals him learning to shape experience into narrative. Pay attention to the moments when Boswell steps back to reflect on his own methods—they are the first signs of the biographer he would become.
