The blockade off Georgetown, S. C.
--The Charleston, S. C., Courier, of the 2d instant has received a letter from a gentleman living near Georgetown, South Carolina, which says:‘ "Our little harbor has been watched for some time by a large bark, doubtless one of Lincoln's apes. It has more the appearance of a full grown mastiff searching for mice than a man of war vessel.
"The rice crop in this section is very good and the harvest nearly over. If abraham I. wishes to procure some for his subjects, he has only to send and we are prepared to give his ambassador a warm reception."
