man who showed us how to hurl our messages thousands of miles through
space without the aid of wire? And how much did the man earn who taught
us how to wrap the human voice around a little cylinder so that it can
be laid away and echo throughout the ages?

Take a very recent invention, the gasolene engine. It has already given
us the automobile and the flying machine, and heaven only knows what yet
may come with that gasolene engine. My first ride in an automobile was
taken in the campaign of 1896; since then something like seventeen
million automobiles have been brought into use.

Have you thought of the value of the ice machine? In Apalachicola,
Florida, they have erected a little monument to a former citizen, Dr.
John Gorry. A statue of him will be found in the capitol at Tallahassee,
and the state of Florida has put another in the Hall of Fame at
Washington. Out of his brain came the idea that made it possible for the
world to have ice to-day without regard to the temperature outside. What
did Gorry earn when he gave the world the ice machine?

When I first visited the Patent Office at Washington I saw a model of
the first sewing machine. On it was a card on which was written:

"Mine are sinews superhuman,
Ribs of brass and nerves of steel;
I'm the iron needle woman,
Born to toil but not to feel."

What did the man earn who gave the world a sewing machine?

These are only a few of the great inventions. Let us take up another
group. To show how wide is the field of measureless endeavour, I call
attention to the work of scientists. Who will measure the value of
anesthetics in the treatment of disease and injury? What of vaccination
and the labours of Pasteur? Who will estimate the value of the service
rendered by the man who gave us a remedy for typhoid? In 1898 hundreds
died of typhoid fever in the little army that was raised for the war
with Spain--twenty-seven of my regiment died of that disease. Now we
have a remedy so complete that of the nearly a million men who reached
the battle-line in France not one died of typhoid, and only one hundred
and twenty-five of the four millions called to the colours.

Have you tried to estimate the service rendered by Reed, who, in finding
a remedy for yellow fever, made the tropics habitable and made it
possible for the United States to add the Panama Canal to our great
achievements?

But the field is larger still. Raikes established a Sunday school and
