sumption, with a gratuity to our faithful female servant* 

 Every Saturday night we cancelled the bill, and Mrs. Her- 

 riott's gain was in the rent of her apartments. My asso- 

 ciates were, except myself, the only men from New England 

 in the University, and as we were congenial, we formed a 

 happy domestic society. There were attending the lectures 

 more than thirty Americans, chiefly from the South. My 

 companions became distinguished in afterlife, Dr. Gor-

 entirely possessed of your subject, and never to venture on 

 an experiment of whose success you are doubtful." I bowed 

 respectfully my assent, adding at the same time that I was 

 happy to find that I had begun right, for I had hitherto

 tending the gratuity both as a reward for her fidelity and as a comfortable 

 addition to her small wages; but we were sorry and displeased to learn late 

 in the season that she was compelled to pay this money over to her mistress, 

 whilo the poor girl was going barefoot m the winter.
