Isabel could not but suppose that Delaford, if it were he, might have exaggerated poor Charlotte's little flirtation; but there was small comfort here, since contradiction was impossible. The U. S., over which the poor child had puzzled in vain, was no field in which to follow him up--he had not even dated his letter; and it was a very, very faint hope that Lord Fitzjocelyn might trace him out, especially as he had evidently fled in disgrace; and poor Charlotte sobbed bitterly over his troubles, as well as her own. She was better after she had told her mistress, though still she shrank from any other sympathy. Even Jane's pity would have been too much for her, and her tender nature was afraid of the tongues that would have discussed her grief. Perhaps the high-toned nature of Isabel was the very best to be brought into contact with the poor girl's spirit, which was of the same order, and many an evening did Isabel sit in the twilight, beside the children's beds, talking to her, or sometimes reading a few lines to show her how others had suffered in the same way. 'It is my own fault,' said poor Charlotte; 'it all came of my liking to be treated like one above the common, and it serves me right. Yes, ma'am, that was a beautiful text you showed me last night, I thought of it all day, and I'll try to believe that good will come out of it. I am sure you are very good to let me love the children! I'm certain sure Miss Salome knows that I'm in trouble, for she never fails to run and kiss me the minute she comes in sight; and she'll sit so quiet in my lap, the little dear, and look at me as much as to say, 'Charlotte, I wish I could comfort you.' But it was all my own fault, ma'am, and I think I could feel as if I was punished right, so I knew poor Tom was happy.' 'Alas!' thought Isabel, after hearing Charlotte's reminiscences; 'how close I have lived to a world of which I was in utter ignorance! How little did we guess that, by the careless ease and inattention of our household, we were carrying about a firebrand, endangering not only poor Walter, but doing fearful harm wherever we went!' CHAPTER XXI. STEPPING WESTWARD. On Darien's sands and deadly dew. Rokeby. Enterprise and speed both alike directed Fitzjocelyn's course across the Isthmus of Panama, which in 1853 had newly become practicable for adventurous travellers. A canal conducted him as far as Cruces, after which he had to push on through wild forest and swamp, under the escort of the muleteers who took charge of the various travellers who had arrived by the same packet.
