When petroleum was discovered in the fields near Pittsburgh, some ten years ago, Mr. Westinghouse was greatly interested, and at once suggested that perhaps oil might be found near his own home in Washington County. He decided to test the matter, and planted a derrick on his own grounds. The drill was started in December, 1883, and at a depth of 1,560 feet a vein was struck, not of oil, as was anticipated, but--what had not been counted upon as among the contingencies--of gas. Gas was not what Westinghouse was after or wanted, but there it was, and not wishing to let it run to waste, he began to consider what use could be made of it. Other people who had been boring for oil also struck gas, which, taking fire, shot up twenty or thirty feet. If such gas could be made to serve foundry purposes, here was a gigantic power going to waste. Within three years the business grew to be an immense one. The company organized by Mr. Westinghouse owned or controlled fifty-six thousand acres, upon which were one hundred wells and a distributing plant of four hundred miles of pipes. Notwithstanding the failure of some of the wells since then, natural gas is an extraordinary boon for which Pittsburgh has to thank Mr. Westinghouse. Of late years this inventor's energies have been turned toward electric machinery for lighting and power, especially as applied to railroad purposes, and a number of useful devices have resulted. Mr. Westinghouse is still in the prime of life and is activity personified. He makes his home in Pittsburgh, and is naturally looked upon as one of its leading spirits. The field of electric invention is so vast and so actively worked that one cannot take up a newspaper without finding reference to some new achievement made possible by this wonderful agent, whose real powers were unsuspected fifty years ago. Aside from the direct value of these inventions in promoting the comfort and increasing the wealth of the country there is another factor to be considered having the most vital relation to the industries of the country and its powers of production. The large number of inventions made in these United States implies a high degree of intelligence and mental activity in the great body of the people. It indicates trained habits of observation and trained powers of applying knowledge which has been acquired. It shows an ability to turn to account the forces of Nature and, train them to the service of man, such as has been possessed by the laborers of no other country. It suggests as pertinent the inquiry whether any other country is so well equipped for competition in production as our own; whether in any other country the mechanic is so efficient and his labor, therefore, so cheap as in our own; whether he does not exhibit the seeming paradox of receiving more for his labor than in any other country, and at the same time doing more for what he receives. THE END.
