Ardgillan Castle (I think by courtesy, for it was eminently, peaceful in character, in spite of the turret inhabited by my dear "moping owl," H----) was finely situated on an eminence from which the sea, with the picturesque fishing village of Skerries stretching into it on one side, and the Morne Mountains fading in purple distance beyond its blue waters on the other, formed a beautiful prospect. A pine wood on one side of the grounds led down to the foot of the grassy hill upon which the house stood, and to a charming wilderness called the Dell: a sylvan recess behind the rocky margin of the sea, from which it was completely sheltered, whose hollow depth, carpeted with grass and curtained with various growth of trees, was the especial domain of my dear H----. A crystal spring of water rose in this "bosky dell," and answered with its tiny tinkle the muffled voice of the ocean breaking on the shore beyond. The place was perfectly lovely, and here we sat together and devised, as the old word was, of things in heaven, and things in earth, and things above heaven, and things below earth, and things quite beyond ourselves, till we were well-nigh beside ourselves; and it was not the fault of my metaphysical friend, but of my utter inability to keep pace with her mental processes, if our argument did not include every point of that which Milton has assigned to the forlorn disputants of his infernal regions. My departure from Dublin ended these happy hours of companionship, and I exchanged that academe and my beloved Plato in petticoats for my play-house work at Liverpool. The following letter was in answer to one Mrs. Jameson wrote me upon the subject of a lady whom she had recommended to my mother as a governess for my sister, who was now in her sixteenth year. LIVERPOOL, August 16, 1830. MY DEAR MRS. JAMESON,
