All the works heretofore brought before the public proposing to meet this want have been fragmentary, or have treated at too great length but a portion of the subject. A complete summary, or Citizens’ Manual, is here furnished, that includes a sufficiently detailed Analysis of the entire structure of the government, developing in a clear and comprehensive manner the organization, powers, relations, and mode of working of each department, small or large, the principles on which they rest and the spirit that permeates them all. It lays our history so far under contribution as to show us the occasion that produced each institution, the gradual growth of the grand edifice and the causes that controlled and shaped the whole. In short, it gives us an adequate reason for the form of our institutions, even so far back as the earlier history of humanity, when the tendencies that have borne this fruit first began to appear in human history. THE PUBLISHER. INTRODUCTION. It is our happiness to live in an age whose master-pieces of accomplishment, in science, industry and commerce, put to shame the extravagant fictions of Oriental tales and the wonders ascribed to the gods and heroes of ancient mythology. The changes produced by recent investigations and discoveries are so vast and so rapid that it is difficult to follow them or comprehend the power and thoroughness of the transformations that are taking place in the world around us. The applications of steam and electricity astonish us by their wide spread influence on the condition and relations of men; the ease and speed of movement and intercourse, constantly increasing, are ever putting us in new and unfamiliar situations. We have hardly accustomed our thoughts and habits to one before we are hurried on into another. The constantly clearer and more abundant light shed by science and the press does not suffice to keep our minds fully up to the progress that goes on in all departments of life. It is plain that we have entered on a New Era, the most extraordinary and momentous the world has ever seen. The old and imperfect is being cleared away and everything thoroughly reconstructed. The explanation is that we are now setting up the grand Temple of Civilization, the separate stones and pillars of which each nation and age was commissioned to hew and carve, and, so to speak, left in the quarry to await the time when, all the material being ready, the Master Builder should collect all the scattered parts and raise the whole edifice at once, to the astonishment and joy of mankind.
