The correspondence between them and Thomas was a remarkable one.  It embraced the following subjects:  Peace, Temperance, the Classics, the Priesthood, the Jewish Dispensation, Was the Eagle the Babylonian and Persian Standard?  Catholicism, and the universality of human sacrifice, with short discussions on minor controversial topics.  Into all of these Angelina especially entered with great and evident relish, and her long letters, covering page after page of foolscap, would certainly have wearied the patience of any one less interested than Thomas was in the subjects of which they treated.  That which claimed Sarah’s particular interest was Peace, and she held to her brother’s views to the end of her life.  She especially indorsed the sentiment expressed in his written reply to the question, what he would do if he were mayor of Charleston and a pirate ship should attack the city?

“I would,” he answered, “call together the Sunday-school children and lead them in procession to meet the pirates, who would be at once subdued by the sight.”

In answer to a letter written by Sarah soon after her arrival in Charleston, Angelina says:—­

“I am not at all surprised at the account thou hast given of Carolina, and yet am not alarmed, as I believe the time of retribution has not yet fully come, and I cannot but hope that those most dear to us will have fled from her borders before the day of judgment arrives.”

This refers to nullification, which was threatening to end in bloodshed; but there is in the sentence also an evident allusion to slavery.

In her next letter she describes the interest she feels in the infant school, of which she had become a teacher, and does not know which is the most absorbing,—­that, or the Arch Street prison.  Before closing, she says:—­

“No doubt thou art suffering a double portion now, for in a land of slavery there is very much daily—­yea, almost hourly,—­to try the better feelings, besides that suffering which thou art so constantly enduring.”

Catherine Morris must have acted the part of a good mother to both Sarah and Angelina, for they frequently refer to their peaceful home with her.  In one of her letters Angelina says,—­

“I never valued the advantages I enjoy so much as I do now; no, nor my home, either, dear sister.  Many a time of late has my heart been filled with gratitude in looking at the peaceful shelter provided for me in a strange land.  It is just such a home as I would desire were I to have a choice, and I often ask why my restless heart is not quite happy in the land of ease which has been assigned me, for I do believe I shall, in after life, look back upon this winter as one of peculiar favor, a time granted for the improvement of my mind and my heart.”

Again:  “Very often do I contrast the sweet, unbroken quiet of the home I now enjoy with the uncongenial one I was taken from.”

In one of her letters she asks:  “Dearest, does our precious mother seem to have any idea of leaving Carolina?  Such seems to be the distressing excitement there from various causes, that I think it cannot be quite safe to remain there.  What does brother Thomas think will be the issue of the political contest?  I find the fate of the poor Indians is now inevitable.”
