Measured by the standards of men of their time, [the Pilgrims] were the humble of the earth. Measured by later accomplishments, they were the mighty. In appearance weak and persecuted they came -- rejected, despised -- an insignificant band; in reality strong and independent, a mighty host of whom the world was not worthy destined to free mankind.
Calvin CoolidgeWhenever Nature's bounty is in danger of exhaustion, the chemist has sought for a substitute. The conquest of disease has made great progress as a result of your efforts. Wherever we look, the work of the chemist has raised the level of our civilization and has increased the productive capacity of the nation. Waste materials, formerly cast aside, are now being utilized.
Calvin Coolidge
