Dear Shareholder:

Enclosed please find a proxy statement soliciting your vote as a
shareholder in the Putnam Money Market Fund on a number of
important proposals.  Please take a few moments to review this
material to determine how you wish to vote.  Below is a brief
explanation of the proposals that are being recommended:

Proposal one -- recommends that shareholders of the fund adopt
the slate of Trustees for the fund.

Proposal two -- recommends the selection of Price Waterhouse as
the independent auditor of the fund for the current fiscal year.

Proposal three -- seeks to allow your fund to invest in certain
so-called "restricted securities."  Putnam Management believes
restricted securities can provide attractive investment
opportunities for your fund.  Restricted securities have
restrictions on how they can be sold.  They often trade in
smaller markets and may be considered less "liquid" when it comes
time to sell them.  Restricted securities are often not sold to
the general public and are frequently purchased by large
institutional investors who have experience trading them.

Recently, the SEC has changed its policy regarding the purchase
of restricted securities by mutual funds.  Up to 10% of a money
market fund's assets may now be invested in such securities and
certain restricted securities that are traded by institutional
investors in relatively liquid markets may be purchased without
limit by a fund. This proposal would bring your funds's
restriction in line with the new SEC guidelines as well as give
the fund's managers greater flexibility in achieving the fund's
investment objectives.

Proposal four -- seeks to allow your fund to invest in a greater
percentage of a single class of a company's securities.  This
would allow the fund to invest in any amount of securities issued
by a company, including certain classes of high-quality
commercial paper, as long as the fund does not own more than 10%
of the company's outstanding voting securities.  This proposal
would bring your fund's restrictions in line with SEC guidelines. 
The proposed changes would give fund manager's greater
flexibility to help the fund achieve its objective and they would
bring the fund's investment policies in line with most other
Putnam funds.

Even if you are not currently a shareholder in the Putnam Money
Market Fund, you are still eligible to vote.  Please do not
hesitate to do so.  Votes are solicited from shareholders of
record as of April 21, 1995.


In addition to providing you with this information on the
proposals, we want to let shareholders know that the fund may
also arrange to have votes recorded by telephone.  A description
of the vote-by-phone process is outlined in the enclosed proxy
statement.

As you may know, voting your proxy, and doing so promptly,
prevents the fund from having to send out additional mailings. 
If you have any questions about the proposals under
consideration, please do not hesitate to call 1-800-225-1581.

Sincerely,

George Putnam
