HELPER, ESQ., (New York,) _Dear Sir_:-- Yours of the 9th has just been received, I sent you, through the Clerk of Council, some time ago, the Annual Fiscal Statement of the Committee on Accounts made to the City Council, which would give some of the information which you desire. I will have another copy sent you. No census has been taken since 1848. The population at present must be between fifty and sixty thousand. Any information which it may be in my power to furnish you with, will always give me pleasure to supply. Very respectfully, WM. PORCHER MILES, _Mayor_. From a report of the "Annual accounts of the city of Charleston, for the fiscal year ending the 31st of August, 1856," it appears that the total value of real and personal property, including slaves--nearly half the population--was $36,127,751.

MAYOR'S OFFICE, } Louisville, Ky., January 1st, 1857.} H. R. HELPER, ESQ., New-York City, _Dear Sir_:-- Your favor 24th ult. is received--contents noted. I will remark in reply, that the taxes of this city are levied only on real estate, slaves, and merchandise, (exclusive of home manufactures,) which are taken at what is supposed to be their cash value, but is much less than the real value. Our last assessment was made the 10th January, 1856, and amounted to $31,500,000. There has been no census of this city taken since 1850, our charter requiring that it shall be taken this year. I am now preparing to have it done. It is supposed Louisville at this time has a population of 65 or 70 thousand.
