Proclamation 665—Thanksgiving Day, 1906
By the President of the United States of America
The time of year has come when, in accordance with the wise custom of our forefathers, it becomes my duty to set aside a special day of thanksgiving and praise to the Almighty because of the blessings we have received, and of prayer that these blessings may be continued. Yet another year of widespread well-being has passed. Never before in our history or in the history of any other nation has a people enjoyed more abounding material prosperity than is ours; a prosperity so general that it should rouse in us no spirit of reckless pride, and least of all a spirit of heedless disregard of our responsibilities; but rather a sober sense of our many blessings, and a resolute purpose under Providence, not to forfeit them by any action of our own.
Material well-being, indispensable though it is, can never be anything but the foundation of true national greatness and happiness. If we build nothing upon this foundation, then our national life will be meaningless and empty as a house where only the foundation has been laid. Upon our material well-being must be built a superstructure of individual and national life in accordance with the laws of the highest morality, or else our prosperity itself will in the long run turn out a curse instead of a blessing. We should be both reverently thankful for what we have received, and earnestly bent upon turning it into a means of grace and not of destruction.
Accordingly, I hereby set apart Thursday, the 29th day of November next, as a day of thanksgiving and supplication, on which the people shall meet in their homes or their churches, devoutly to acknowledge all that has been given them, and to pray that they may in addition receive the power to use these gifts aright.
In Witness Whereof, I have hereunto set my hand and caused the seal of the United States to be affixed.
Done at the city of Washington, this the 22nd day of October in the year of our Lord 1906, and of the independence of the United States 131st.
