Gentlemen:

Pursuant to Rule 14a-6 under the Securities Exchange Act of 1934, as amended, 
transmitted herewith for filing is a copy of a supplement to proxy materials 
previously filed with the Commission on behalf of the Dreyfus Family of Funds.
The filing fee of $125 was forwarded prior to filing the preliminary proxy 
materials.

It is estimated that the supplement will be mailed to stockholders of record 
on or about July 1, 1994.     



 
 
                          THE DREYFUS FAMILY OF FUNDS
 
Dear Dreyfus Fund Stockholder:
 
  You were previously sent proxy materials in connection with an upcoming
Meeting of Stockholders. According to our latest reports, your signed Proxy
Card has not been returned. As a separate card must be voted for each Dreyfus
Fund you own, you may have received requests to return more than one Proxy
Card.
 
  Since the Meeting is only a short time away, please take a moment to
complete, sign, date and mail the enclosed duplicate Proxy Card at your
earliest convenience. Regardless of the number of shares you own, it is
important that your shares are represented at the Meeting.
 
  On behalf of Dreyfus, thank you for your prompt response and your continued
interest in the Dreyfus Family of Funds. Since a separate Proxy Card is needed
for EACH Fund in which you own shares, if you are sure that you have recently
mailed a Proxy Card for this specific Fund, please accept our thanks and
disregard this letter. If you have any remaining questions, please call
D.F. King & Co., Inc., which has been engaged to solicit proxies on behalf of
your Fund's Board, at 1-800-859-8515.
 
                               Very truly yours,
