I had supposed that there were limitations upon the freedom of this meeting this afternoon, both as to the Governor and myself, and that no political suggestion of any sort was to be introduced into this friendly concourse of American citizens; and I think both of us have good cause for grievances against the prohibitionists for interrupting us with this argument for cold water. [Great laughter and applause.] It is quite difficult, called upon as I am every day, and sometimes three or four times a day, to make short addresses with the limitations that are upon me as to the subjects upon which I may speak, to know what to say when I meet my fellow-citizens. I was glad to hear the Governor say that Iowa is prosperous. We have here a witness that it is so. It offers also, I think, a solution of the origin of that prosperity, and suggests how it may be increased and developed. We have in this structure a display of all the products of the farm, and side by side with it a display of the mechanic arts. I think in this combination, in this diversity of interest and pursuit, in this mutual and helpful relation between the toilers of the soil and the workers in our shops, each contributing to the commonwealth and each giving to the other that which he needs, we have that which has brought about the prosperity you now enjoy, and which is to increase under the labors of your children to a degree that we have not realized. The progress in the mechanical arts that men not older than I have witnessed, the application of new agencies to the use of men within the years of my own notice and recollection, read like a fairy tale. Let us not think that we have reached the limits of this development. There are yet uses of the agencies already known to be developed and applied. There are yet agencies perhaps in the great storehouse of nature that have not been harnessed for the use of man. The telegraph, the telephone, and the phonograph have all come within the memory of many who stand about me to-day. The application of steam to ocean travel is within the memory of many here. The development of our railroad system has all come within your memory and mine. The railroad was but a feeble agency in commerce when my early recollection begins; and now this great State is covered with railroads like a network. Every farm is within easy reach of a shipping station, and every man can speak to his neighbor any day of the week, though that neighbor live on the opposite side of the globe. Out of all this what is yet to come? Who can tell? You are favored here in having not only a surface soil that yields richly to the labor of the farmer, but in also having hidden beneath that surface rich mines of coal which are to be converted into power to propel the mills that will supply the wants of your people.
