Excerpt from Three Kingdoms: A Handbook of the Agassiz Association Darwin's service to science would have been much slighter in its immediate effect had it not been for the multitude of teachers who echoed his voice in every institution of learning, and the lecturers who repeated his theme with infinite variations from every rostrum and newspaper throughout the civilized world. Fortunately for the future of science in this country, there is now a daily increasing popular constituency. This has been largely gained by the unselfish and unrewarded efforts of investigators, and also by a growing disposition on their part to help forward all organizations having the education of the public in view.
