Success was now assured; honors and riches were his, and those who had been slow to believe in the utility of his invention were now proud of their countryman and delighted to do him homage. Upon going abroad again he was received more as a prince than as a plain American citizen, kings and their subjects giving him honor. It may be believed that even in his wildest flights of fancy Professor Morse did not dream of the rapid spread of the use of his invention, or look forward to the time within a few years, when the telegraph wires would weave together the ends of the world and form a network over the entire Continent.
A few years ago, the only telegraph wire in China was one about six miles in length, stretching from Shanghai to the sea, and used to inform the merchants of the arrival of vessels at
the mouth of the river. A line from Pekin to Tientsin was opened a short time since. The capital of Southern China is in communication with the metropolis of the North, and as Canton was connected by telegraph with the frontier of Tonquin at the outbreak of the late political troubles, the telegraph wires now stretch from Pekin to the most southern boundary of the Chinese Empire, and China, ever slow to adopt foreign ideas, is crossed and re-crossed by wires; we may say the thought which came to Prof. Morse upon that memorable voyage has reached out and taken in the whole world.
CHAPTER XVI.
NEWTON, SIR ISAAC.
"Every body in nature attracts every other body with a force directly as its mass and inversely as the square of its distance." This has been called "The magnificent theory of universal gravitation which was the crowning glory of Newton's life." I doubt not many of you have struggled manfully with this law as laid down in your school-books, and, having conquered it, and fixed the principle in your minds to stay, you may like to know something about the philosopher himself. In 1642, a puny, sickly baby was supposed to be moaning away its young life in Lincolnshire, England.
SIR ISAAC NEWTON.
This child's name was Isaac Newton. He belonged to a country gentleman's family. His father having died, his mother's second marriage occasioned the giving of the child into the care of his grandmother. As he grew older
