5. The habitual scientific use of events which happen around us.

6. The study of the old to find the new. The principle of the telephone,

for instance, is as old as spoken language. The mere[1] pulses in the

air--carrying all the characteristics of what you say--may set in

vibration either the drum of my ear, or a disk of metal. How simple--and

how simple all true science is--when we understand it.

[Transcribers note 1: corrected from 'more']

8. The cultivation of the scientific judgment, and the inventive powers

of the mind. One great original investigator, made such by the direction

given his mind in one of our common schools, would be cheaply bought at

the price of all that the study of science in our schools will cost for

the next quarter of a century.

8. Honesty. If there is a study whose every tendency is more in the

direction of honesty and truthfulness--both with ourselves and with

others--than is the study of experimental science, I do not know what it

is.

Physical science, then, will help in making men and women out of our

boys and girls. It is worthy of a fair, earnest trial everywhere.

A few minutes each day in which a class or a school study science in

some of the ways I have indicated will give a knowledge at the end of a

term or a year of no mean value. The time thus spent will have rested

the pupils from their books, to which they will return refreshed, and

instead of being time lost from other study the work will have been made

enough more earnest and intense to make it again.

Apparatus for illustrating many of the ordinary facts of physics can be

devised from materials always at hand. Many more can be made by any

one skilled in the use of tools. In chemistry, the simplicity of the

apparatus, and comparative cheapness of ordinary chemicals, make the use

of a large number of beautiful and instructive experiments both easy and

cheap.

A nation is what its trades and manufactures--its inventions and

discoveries--make it; and these depend on its trained scientific men.

Boys become men. Their growing minds are waiting for what I urge you

to offer. Science has never advanced without carrying practical

civilization with it--but it has never truly advanced save by the use of

the experimental method. _And it never will_.

Let us then look forward to the time when our boys and young men--our

girls and young women--shall extend the boundaries of human knowledge by

its use, fitted so to do by what we may have done for them.
