"In working out this problem there has been much conflict. Indeed, according to human experience, such conflict could not entirely be avoided, but in the end each class must recognize that it cannot exist independently of others; it cannot strike down or defeat the rights or interests of others without injuring itself. Should capital demand more than its due, by that demand it limits its opportunities, and, correspondingly, the laborer who demands more than his due thereby takes away from himself the opportunity to labor. No one can escape this law of co-operation. Self-interest demands that we must observe its just limitations. We must be ready to do our part and accord to all others the fair opportunity of doing their part. We must co-operate with and help our colaborer. We should approach the solution of each question which may arise with a reasonable and, better still, a friendly spirit. He who obstructs the reasonable adjustment of these questions, who fosters strife by appealing to class prejudice, may justly be regarded by all as an enemy to the best public interests.... "In conclusion, permit me to advert to the Louisiana Purchase, which we are now celebrating, and call attention to the importance of that event in securing to our people the fullest benefit of the co-operative idea. Manifestly, if our Government were restricted to the original territory of the United States, as defined by the Treaty of 1783, we must have encountered in many ways the opposition of governments, some of them European, which would have occupied the territory beyond our original south and west boundaries. Our trade and commerce moving from or to our original territory would, necessarily, have been largely restricted by hostile foreign powers. The Louisiana Purchase not only more than doubled our territory by adding a country rich in material resources, but gave us control of the Mississippi river, and made possible the acquisition of the Oregon Territory, the Mexican cessions and the annexation of Texas. ... "Though much has been done towards the development of this imperial domain, yet we may truly say that we have only seen the beginning of that development. The possibilities for the future are boundless. With a land of unparalleled resources, occupied by a people combining the best elements of our modern civilization and governed by laws evolved from the highest and best progress of the human race, no eye can foresee the goal to which a co-operation of all these forces must lead." The Mexican Commissioner, A. R. Nuncio, spoke in behalf of the foreign exhibitors. The concluding address was made by Hon. William H. Taft, Secretary of War, who attended as the special representative of the President. At its conclusion the President of the United States, in the White House at Washington, pressed a key that started the machinery, unfurled the flags, set the cascades in motion, and thus opened the Exposition.
