It has seemed to me that our search for this mysterious factor of difference must lead to the conclusion that it was not a single factor but the unit… - Calvin Coolidge

In such a view of the history of the Negro race in America, we may find the evidences that the black man's probation on this continent was a necessary part in a great plan by which the race was to be saved to the world for a service which we are now able to vision and, even if yet somewhat dimly, to appreciate. The destiny of the great African continent, to be added at length — and in a future not now far beyond us — to the realms of the highest civilization, has become apparent within a very few decades. But for the strange and long inscrutable purpose which in the ordering of human affairs subjected a part of the black race to the ordeal of slavery, that race might have been assigned to the tragic fate which has befallen many aboriginal peoples when brought into conflict with more advanced communities. Instead, we are able now to be confident that this race is to be preserved for a great and useful work. If some of its members have suffered, if some have been denied, if some have been sacrificed, we are able at last to realize that their sacrifices were borne in a great cause. They gave vicariously, that a vastly greater number might be preserved and benefited through them. The salvation of a race, the destiny of a continent, were bought at the price of these sacrifices.

I appreciate how impossible it is to convey an adequate realization of the office of President. A few short paragraphs in the Constitution of the United States describe all his fundamental duties. Various laws passed over a period of nearly a century and a half have supplemented his authority. All of his actions can be analyzed. All of his goings and comings can be recited. The details of his daily life can be made known. The effect of his policies on his own country and on the world at large can be estimated. His methods of work, his associates, his place of abode, can all be described. But the relationship created by all these and more, which constitutes the magnitude of the office, does not yield to definition. Like the glory of a morning sunrise, it can only be experienced it cannot be told.

Army and navy. Little has developed in relation to our national defense which needs special attention. Progress is constantly being made in air navigation and requires encouragement and development. Army aviators have made a successful trip around the world, for which I recommend suitable recognition through provisions for promotion, compensation, and retirement. Under the direction of the Navy a new Zeppelin has been successfully brought from Europe across the Atlantic to our own country.
