In a republican government entire simplicity in all that relates to public affairs, is not only convenient to the officers, but is a duty to the public, every man of whom is a party in the business. We are reminded of the value of simplicity and order by two quarto volumes now before us, which point out the order, and show how simplicity is to be attained in whatever relates to the fiscal department of the government of the United States. The title of these volumes is expressive of their valuable contents. “A Synopsis of the Commercial and Revenue System of the United States, as Developed by Instructions and Decisions of the Treasury Department, for the Administration of the Revenue Laws: Accompanied with a Supplement of Historical and Tabular Illustrations of the Origin, Organization and Practical Operations of the Treasury Department and its various Bureaus, in Fulfillment of that System: In Eight Chapters, with an Appendix. By Robert Mayo, M.D. 2 vols. 4to.” We have not space to enter into details of this truly great work. All that is set forth in the promises of the title page is amply sustained by the body of the work, and an amount of information is given, truly astonishing to those who have not had experience in the numerous ramifications of the overgrown department. While there is scarcely a relation which any citizen could occupy with regard to the treasury department, in all its forms, and while the duty of every officer connected with that branch of government, whatever may be his grade, is amply set forth, it seems as a matter of course that at least one in every hundred of the citizens of this country should have a copy of this instructive work, for the benefit of himself and of the others to whom he is the _centurion_. And while these various kinds of information are given, the work incidentally contains a history of the department. Loan holders, applicants for remuneration, and all who have any connection or business with the treasury department, are instructed by these volumes how to proceed—how they ought to proceed—and how others have proceeded. Dr. Mayo has done a public service by preparing these volumes. We hope the public will remember him and his work. * * * * * _The Women of the Bible; Delineated in a series of Sketches of Prominent Females mentioned in Scripture.
