It is said that serious apprehensions are to some extent entertained (in which I do not share) that the peace of this District may be disturbed before the 4th of March next. In any event, it will be my duty to preserve it, and this duty shall be performed.
In conclusion it may be permitted to me to remark that I have often warned my countrymen of the dangers which now surround us. This may be the last time I shall refer to the subject officially. I feel that my duty has been faithfully, though it may be imperfectly, performed, and, whatever the result may be, I shall carry to my grave the consciousness that I at least meant well for my country.
