                Re: Vanguard Specialized Funds; File No. 2-88116

Dear Mr. Sandoe:

         Thank you for your comments of July 19, 2005 on the post-effective
amendment of the registration statement of Vanguard Fixed Income Securities
Funds. You commented to Frances Han on post-effective amendment number 52 that
was filed on June 6, 2005 pursuant to Rule 485(a). The following are our
responses to each of your comments. I am responding in Frances's absence. Please
contact me at the number below with any further comments or questions.

Comment 1:  Energy Fund prospectus (p. 1)
Comment:          The Primary Investment Strategies section states that "the
                  Fund invests at least 80% of its assets in the common stocks
                  of companies principally engaged in energy-related
                  activities." Define "energy-related" activities.

Response:         "Energy-related" activities are described in the second half
                  of the sentence quoted above to include "production and
                  transmission of energy or energy fuels; the making of
                  component products for such activities; energy research; and
                  energy conservation or pollution control."

Comment 2:  Energy Fund prospectus (p. 1)
Comment:          Disclose the Fund's market-capitalization strategy in the
                  Primary Investment Strategies section.  To the extent
                  applicable, add mid- and small-cap risk.

Response:         As provided in our response letter to your comments on
                  Vanguard Specialized Funds dated May 20, 2005, we explained
                  that the Fund does not have a specific market-capitalization
                  strategy and will invest across all market capitalization
                  segments. The Fund will not focus on any particular market
                  segment at any particular time for any reason other than to
                  focus on its stated primary investment strategies and
                  objectives. As such, we believe that it would be misleading to
                  characterize a specific market cap as a part of the primary
                  investment strategies, or a particular market cap risk as a
                  primary risk of investing in the Fund.

Comment 3:  Energy Fund prospectus (p. 2)
Comment:          In the Annual Total Returns - Investor Shares bar chart in the
                  Performance/Risk Information section of the prospectus, update
                  the year-to-date return as of the most recent calendar quarter
                  from the figure as of March 31, 2005 to June 30, 2005.

Response:         We will update the sentence immediately below the bar chart to
                  read as follows: "The year-to-date return as of the most
                  recent calendar quarter, which ended on June 30, 2005, was
                  22.70%."

Comment 4:  Energy Fund prospectus (p. 12)
Comment:          In the Plain Talk About The Fund's Portfolio Managers section,
                  clarify that Karl E. Bandtel has been Fund Manager for this
                  Fund since 2002.  Also, identify how long James A. Bevilacqua
                  has managed the Fund, and clarify each portfolio manager's
                  role in the management of the Fund.

Response:         We will revise the disclosure regarding the Fund's portfolio
                  managers as follows:

                  the Fund since 2002; and has co-managed a portion of the
                  Fund since 2005.  Education: B.S. and M.S., University of

                  management with Wellington Management since 1994; has been

                  University in St. Louis; Ph.D., Stanford University.

Comment 5:  SAI (p. B-31)
Comment:          The disclosure concerning Vanguard's portfolio management
                  compensation program discusses bonus payments for portfolio
                  managers. Disclose whether the bonus paid to Joel Dickson as a
                  portfolio manager of the Energy Fund is based on a benchmark
                  over a specified period of time.

Response:         We have added the following statement to the SAI disclosure
                  concerning the portfolio manager's compensation: "For the
                  Energy Fund, the bonus is based in part on the performance of
                  the Vanguard-managed portion of the fund relative to a
                  benchmark over a trailing three-year period. The benchmark is
                  derived from certain energy stocks in the MSCI All Country
                  Index."

Comment 6:  SAI (p. B-33)
Comment:          The disclosure concerning M&G Investment Management Limited's
                  portfolio management compensation program discusses a bonus
                  payment based in part on investment performance. The
                  disclosure states that "the performance factor of the fund
                  manager's bonus is dependent on the Fund's performance over
                  one- and three-year periods compared with a representative
                  group of competitor funds." If applicable, identify with more
                  specificity the benchmark used, such as the Fund's Morningstar
                  or Lipper peer group.

Response:         We will respond to this comment in a separate letter and, if
                  applicable, address any disclosure changes in future filings.
