An extract from his Presentation Address is as follows:
"Upon Mr. Mather's death last year friends associated themselves in the Stephen T. Mather Appreciation for the purpose of creating a suitable memorial to him. The one finally chosen is in the form of a plaque bearing as its inscription the words of the Honorable Louis C. Cramton regarding Mr. Mather. One of these plaques is today being presented and dedicated in each of the national parks - themselves a memorial to our departed friend, a great citizen and a devoted public servant.
"As a member of the national committee, the Stephen T. Mather Appreciation and on its behalf it is my honor and privilege to present this plaque to Crater Lake National Park to be set up here as a perpetual memorial to Stephen T. Mather. In the words of in inscription, 'He laid the foundation of the National Park Service, defining and establishing the policy which its areas shall be developed and conserved unimpaired for future generations. There will never come an end to the good that he has done.'"
