Since that time astonishing changes have been wrought in the condition and prospects of the American people; and a degree of progress witnessed with which the world can furnish no parallel. As we review the course of that progress, wonder and amazement arrest our attention at every step. The present occasion, although allowing of no lengthened remarks, may yet, perhaps, admit of a short comparative statement of important subjects of national interest as they existed at that day, and as they now exist. I have adopted for this purpose the tabular form of statement, as being the most brief and significant.[47] COMPARATIVE TABLE Year 1793. Year 1851. Year 1900.
