	File No. 2-47371
Commissioners:
Enclosed is the 114th Post-Effective Amendment to the Trust’s Registration Statement on Form
N-1A, which we are filing pursuant to Rule 485(a)(2) under the Securities Act of 1933. The
purposes of this Amendment are (1) to add Vanguard REIT II Index Fund, a new series of the
Trust and (2) to effect a number of non-material editorial changes.
Pursuant to the requirements of Rule 485(a)(2), we request that the Amendment become
effective on September 26, 2017. Prior to the effective date of the Amendment, Vanguard will
submit a Rule 485(b) filing that will include text addressing any SEC staff comments.
If you have any questions or comments concerning the enclosed Amendment, please contact
me at (610) 669-2616.
Sincerely,
Lance R. Barrett
Associate Counsel
The Vanguard Group, Inc.
