I cannot but look upon this discovery of oil in the earth as one of the most remarkable and instructive revelations of the age. It has shown to me that, whenever human necessity demands any thing of the world of matter, the demand will be honored. Whenever animal life, or the muscle of man or brute, has shown itself unequal to the wants of an age, Nature has always responded to the cry for help. Inventors are only men who act as pioneers, and who go forward to see what the human race will want next, and to make the necessary provisions. An inventor has profound faith in the exhaustless resources of nature. He knows that if he bores far enough, and bores in the right direction, he will find that which the world needs. He is often no more than the discoverer of a secret which nature has kept for the satisfaction of the wants of an age. A lake yoked to a coal-bed would generally be voted a slow team, but the inventor of the steam engine saw how it could be made a very fast and a very powerful one; and we who live now are able to see that the discovery was made at the right time, and that, for the emergencies of this latter day, it has really quadrupled the power of civilized man. Think how nature has risen grandly up to meet every occasion for new resources. The revolution wrought by steam in the business of the world created great wants, every one of which was filled as soon, as felt. Quicker modes of communicating thought were needed to give us all the advantages of the increased facility of carriage, and Mr. Morse was permitted to uncover the telegraph. More money was wanted for the increased business of the world, and the gold fields of California and Australia were unveiled. It has always been so. In the march of the human race along the track of history, nature has pulled aside the veil in which she hides her treasures, to display that which she has kept in store for every epoch. In all the future I have no doubt that whenever oil shall be wanted, oil will be had for the boring. The world is fitted up with supplies for all the probable and possible wants of the human race. We are treading every day upon the lids of great secrets that await the wants of the larger style and finer type of life that lie before us. Discovery has but just begun, and will, I doubt not, be as rife in future ages as in this. There is no end of it: yet the world is a thing to be weighed and measured. It is so many miles around it, and so many miles through it. Never mind; it has more in it than humanity can exhaust.
