INDEPENDENT AUDITORS' REPORT

To the Trustees and Shareholders of Massachusetts Investors Trust:

In  planning  and   performing   our  audit  of  the  financial   statements  of
Massachusetts Investors Trust (the "Trust") for the year ended December 31, 1999
(on which we have issued our report dated  February 3, 2000),  we considered its
internal control,  including control activities for safeguarding securities,  in
order to determine our auditing  procedures  for the purpose of  expressing  our
opinion on the financial  statements and to comply with the requirements of Form
N-SAR, and not to provide assurance on the Trust's internal control.

The  management of the Trust is responsible  for  establishing  and  maintaining
internal control. In fulfilling this responsibility,  estimates and judgments by
management  are  required to assess the expected  benefits and related  costs of
controls.  Generally,  controls  that are  relevant  to an audit  pertain to the
entity's objective of preparing financial  statements for external purposes that
are  fairly   presented  in  conformity  with  generally   accepted   accounting
principles.   Those  controls   include  the   safeguarding  of  assets  against
unauthorized acquisition, use or disposition.

Because of inherent  limitations in any internal  control,  misstatements due to
error or fraud may occur and not be detected. Also, projection of any evaluation
of internal  control to future  periods is subject to the risk that the internal
control  may become  inadequate  because of  changes in  conditions  or that the
degree of compliance with policies or procedures deteriorates.

Our consideration of the Trust's internal control would not necessarily disclose
all  matters  in  internal  control  that  might be  material  weaknesses  under
standards established by the American Institute of Certified Public Accountants.
A material  weakness is a condition  in which the design or  operation of one or
more of the internal  control  components  does not reduce to a  relatively  low
level the risk that misstatements caused by error or fraud in amounts that would
be material in relation to the financial  statements being audited may occur and
not be detected  within a timely  period by  employees  in the normal  course of
performing their assigned functions.  However, we noted no matters involving the
Trust's internal control and its operation,  including controls for safeguarding
securities  that we consider to be material  weaknesses  as defined  above as of
December 31, 1999.

This report is intended solely for the  information  and use of management,  the
Board  of  Trustees,  and the  Securities  and  Exchange  Commission  and is not
intended  to be and  should not be used by anyone  other  than  these  specified
parties.

                          MASSACHUSETTS INVESTORS TRUST


                           CERTIFICATION OF AMENDMENT
                           TO THE DECLARATION OF TRUST

                          ESTABLISHMENT AND DESIGNATION
                                    OF CLASS


         The  undersigned,  being a majority of the  Trustees  of  Massachusetts
Investors  Trust  (the  "Trust"),  a  trust  organized  under  the  laws  of The
Commonwealth of Massachusetts pursuant to a Declaration of Trust dated March 21,
1924, as amended (the  "Declaration"),  acting pursuant to Article VIII, Section
1A of the  Declaration,  do hereby  divide  the shares of the Trust to create an
additional class of shares,  within the meaning of Article VIII,  Section 1A, as
follows:

         1.       The additional class of shares is designated "Class J Shares";

         2.       Class  J  Shares  shall  be  entitled  to all the  rights  and
                  preferences accorded to shares under the Declaration;

         3.       The purchase price of Class J Shares, the method of
                  determination of the net asset value of Class J Shares, the
                  price, terms and manner of redemption of Class JShares, and
                  the relative dividend rights of holders of Class J Shares
                  shall be established by the Trustees of the Trust in
                  accordance with the Declaration and shall be set forth in the
                  current prospectus and statement of additional information of
                  the Trust or any series thereof, as amended from time to
                  time, contained in the Trust's registration statement under
                  the Securities Act of 1933, as amended;

         4.       Class J Shares  shall vote  together as a single  class except
                  that  Shares  of  a  class  may  vote  separately  on  matters
                  affecting  only that class and Shares of a class not  affected
                  by a matter will not vote on that matter; and

         5.       A class of Shares of any series of the Trust may be terminated
                  by the Trustees by written notice to the  Shareholders  of the
                  class.
