+Le 24 février 1815, la vigie de Notre-Dame de la Garde signala le trois-mâts
+le Pharaon, venant de Smyrne, Trieste et Naples.
+
+Comme d'habitude, un pilote côtier partit aussitôt du port, rasa le château
+d'If, et alla aborder le navire entre le cap de Morgion et l'île de Rion.
+
+Aussitôt, comme d'habitude encore, la plate-forme du fort Saint-Jean s'était
+couverte de curieux; car c'est toujours une grande affaire à Marseille que
+l'arrivée d'un bâtiment, surtout quand ce bâtiment, comme le Pharaon, a été
+construit, gréé, arrimé sur les chantiers de la vieille Phocée, et appartient
+à un armateur de la ville.
+
+Cependant ce bâtiment s'avançait; il avait heureusement franchi le détroit que
+quelque secousse volcanique a creusé entre l'île de Calasareigne et l'île de
+Jaros; il avait doublé Pomègue, et il s'avançait sous ses trois huniers, son
+grand foc et sa brigantine, mais si lentement et d'une allure si triste, que
+les curieux, avec cet instinct qui pressent un malheur, se demandaient quel
+accident pouvait être arrivé à bord. Néanmoins les experts en navigation
+reconnaissaient que si un accident était arrivé, ce ne pouvait être au
+bâtiment lui-même; car il s'avançait dans toutes les conditions d'un navire
+parfaitement gouverné: son ancre était en mouillage, ses haubans de beaupré
+décrochés; et près du pilote, qui s'apprêtait à diriger le Pharaon par
+l'étroite entrée du port de Marseille, était un jeune homme au geste rapide et
+à l'œil actif, qui surveillait chaque mouvement du navire et répétait chaque
+ordre du pilote.
