The fourth section of these parliamentary papers for 1851 amounts to thirty volumes, and consists of _Accounts and Papers_. It is in these that the statist finds inexhaustible wealth of material, long columns of figures with large totals, tables of the most complicated yet the clearest construction, containing a multiplicity of details bearing on the riches and resources of the empire in its most general and most minute particulars. Thus the first volume relates to 'Finance,' and includes the accounts of the Public Income and Expenditure, Public and National Debt, Income Tax, Public Works, and a vast variety of other subjects. The second volume is made up of the 'Estimates' for the Army, Navy, Ordnance, and 'Civil Services,' which includes Public Works, Public Salaries, Law and Justice, Education, Colonial and Consular Services, &c. The third volume is filled with Army and Navy Accounts and Returns. The next six volumes refer to the colonies, and consist of Accounts, Dispatches, Correspondence. The tenth is occupied with the subject of Emigration; and the eleventh with the Government of our Eastern Empire in all its vast machinery and complicated relations. The remaining volumes--for space would fail us to enumerate them in detail--treat of such subjects as the Census, Education, Convict Discipline, Poor, Post-office, Railways, Shipping, Quarantine, Trade and Navigation Returns, Revenue, Population and Commerce, Piracy, the Slave Trade, and Treaties and Conventions with Foreign States. Last of all, as volume sixty of the set, we have the _Numerical List and General Index_, itself a goodly tome of nearly 200 pages, compiled with immense care, and arranged so perspicuously as to afford the utmost facilities for reference. These papers, as we have said, differ greatly in size. Some consist of but a single page, others swell up to volumes two or three inches thick, and of perhaps 2000 pages. As to the contents, the majority display a mixture of letterpress with tabular matter; and while some are wholly letterpress, others present an alarming and endless array of figures--filing along, page after page, in irresistible battalions. In many, valuable maps and plans are incorporated, with occasional designs for public works, &c.
