      RE:        VANGUARD WELLESLEY INCOME FUND

Dear Mr. Sandoe:

     The  following  responds  to  your  comments  of  January  5,  2006  on the
post-effective  amendment of the registration  statement of the above-referenced
registrant.  You commented on Post-Effective  Amendment No. 59 that was filed on
November 21, 2005.

COMMENT 1:  PROSPECTUS - MARKET EXPOSURE
- ----------------------------------------

Comment:   Include an example describing the meaning of the term "duration."

Response:  The glossary  already  includes a definition  of  "duration"  and
           includes an example.

COMMENT 2: SAI - INDUSTRY CONCENTRATION INVESTMENT LIMITATION
- -------------------------------------------------------------

Comment:   How do we reconcile treating "gas," "electric," and "electric and
           gas" as separate industries?

Response:  This likely goes back to our historical reliance on SIC codes for
           industry testing. There are separate SIC codes for gas, electric,
           and "combination" (i.e., electric and gas) utility companies.  We
           have since  moved to testing  based on NAICS  codes  which do not
           have  the  same  level of  aggregation.  Accordingly,  we plan to
           delete the sentence that describes how utility  companies will be
           divided. The 25% investment limitation remains unchanged.

COMMENT 3: SAI - INVESTING WITH VANGUARD THROUGH OTHER FIRMS
- -------------------------------------------------------------------


Comment:   The  disclosure  states  that  "The  Fund  will be deemed to have
           received a purchase or redemption  order when an Authorized Agent
           accepts the order in  accordance  with the Fund's  instructions."
           Does this allow for time to pass between  receiving and accepting
           the order?  If so, there is a potential  for  violations  of Rule
           22c-1.

Response:  We think any confusion  caused by the prior sentence is addressed
           in the  sentence  that  follows  it in  the  SAI.  That  sentence
           explains that "In most instances, a customer order

           that is  properly  transmitted  to an  Authorized  Agent  will be
           priced  at the  Fund's  NAV next  determined  after  the order is
           received by the  Authorized  Agent."  Authorized  Agents will not
           transmit  customer  orders to the Fund until they receive them in
           good order,  and so the Fund would be unable to be deemed to have
           received an order until the Agent has accepted such order.

COMMENT 4: SAI - PORTFOLIO MANAGER COMPENSATION
- ------------------------------------------------------

Comment:   Does the disclosure  regarding other accounts managed include all
           of the investment vehicles contemplated by Form N-1A?

Response:  Yes, although it is not disclosed in a tabular format, the stated
           number of other  accounts  managed  includes  all of the types of
           investment vehicles contemplated by Form N-1A.

COMMENT 5: SAI - INVESTMENT ADVISORY SERVICES
- ----------------------------------------------------


Comment:   The detail  regarding the advisory fee (base fee and  performance
           fee structure) should be included in the SAI.

Response:  We plan to put back some of the disclosure that was pulled in our
           485(a) filing, but not all of it.

           Vanguard  operates a  multi-manager  structure  for certain funds
           pursuant to an exemptive  order granted by the Commission in 2003
           (the "2003  Order").(1)  The funds are  permitted  under the 2003
           Order to enter into and amend investment advisory agreements with
           unaffiliated  third-party advisors without shareholder  approval,
           provided  certain  conditions  are met.  The 2003  Order  exempts
           multi-managed Vanguard funds from certain disclosure requirements
           so that they are only required to disclose advisory fees (as both
           a dollar  amount and as a  percentage  of a fund's net assets) as
           follows:  (1)  aggregate  fees paid by a fund to Vanguard and any
           affiliated  advisors;  (2)  aggregate  fees  paid by the  fund to
           unaffiliated third-party advisors; and (3) aggregate fees paid by
           the fund to all investment advisors (collectively, the "Aggregate
           Fee Disclosure").  A fund using Aggregate Fee Disclosure does not
           have to include  additional  details,  including  asset-based and
           performance  fee  schedules,  about  its  advisory  fees  and fee
           arrangements.

           An Aggregate Fee  Disclosure  regime is in the best  interests of
           fund shareholders.  In a recent proposal to codify  multi-manager
           exemptive   orders,   the  Commission  said  that  fund  sponsors
           (including  Vanguard)  have  represented  that  they "are able to
           negotiate  lower  fees  with  subadvisers  if they do not have to
           disclose  those  fees  separately,  and in  our  orders  we  have
           provided  them relief from our  disclosure  requirements.  We are
           proposing  to codify  this  relief,  which  permits a manager  of
           managers fund to disclose  only the aggregate  amount of advisory
           fees that it pays to subadvisers as a group."(2)

     812-12380,  Inv.  Co. Act Release Nos.  26062 (May 29,  2003)  (Notice) and
     26089 (June 25, 2003) (order).

(2)  Exemption  from  Shareholder  Approval for Certain  Subadvisory  Contracts,
     Securities Act Release No. 8312 (Oct. 23, 2003).
