May 2, 1861.
I have just received Custis’s letter of the 30th, enclosing the acceptance of my resignation. It is stated it will take effect on the 25th of April. I resigned on the 20th, and wished it to take effect on that day. I cannot consent to its running on farther, and he must receive no pay if they tender it beyond that day, but return the whole if need be.
