Glance now at the _Navy_. The Royal Navy of Great Britain consists at present of 557 ships; but deducting such as are used for convict ships, floating chapels, and coal depots, the efficient Navy comprises 88 ships of the line, 109 frigates, 190 small frigates, corvettes, brigs, and cutters, including packets, 65 steamers of various sizes, 3 troop-ships and yachts: in all, 455 ships. Of these, in 1839, 190 were in commission, carrying in all 4,202 guns, with crews numbering 34,465 men. The Navy of France, though not comparable with that of England, is of vast force. By royal ordinance of 1st January, 1837, it was fixed in time of peace at 40 ships of the line, 50 frigates, 40 steamers, and 19 smaller vessels, with crews numbering, in 1839, 20,317 men. The Russian Navy is composed of two large fleets,--one in the Gulf of Finland, and the other in the Black Sea; but the exact amount of their force is a subject of dispute among naval men and publicists. Some idea of the Navy may be derived from the number of hands. The crews of the Baltic amounted, in 1837, to not less than 30,800 men, and those of the Black Sea to 19,800, or altogether 50,600,--being nearly equal to those of England and France combined. The Austrian Navy comprised, in 1837, 8 ships of the line, 8 frigates, 4 sloops, 6 brigs, 7 schooners or galleys, and smaller vessels: the number of men in its service, in 1839, was 4,547. The Navy of Denmark comprised, at the close of 1837, 7 ships of the line, 7 frigates, 5 sloops, 6 brigs, 3 schooners, 5 cutters, 58 gunboats, 6 gun-rafts, and 3 bomb-vessels, requiring about 6,500 men. The Navy of Sweden and Norway consisted recently of 238 gunboats, 11 ships of the line, 8 frigates, 4 corvettes, and 6 brigs, with several smaller vessels. The Navy of Greece has 32 ships of war, carrying 190 guns, with 2,400 men. The Navy of Holland, in 1839, had 8 ships of the line, 21 frigates, 15 corvettes, 21 brigs, and 95 gunboats. Of the untold cost absorbed in these mighty Preparations it is impossible to form an accurate idea. But we may lament that means so gigantic are applied by Christian Europe, in time of Peace, to the construction and maintenance of such superfluous wooden walls. In the _Fortifications and Arsenals_ of Europe, crowning every height, commanding every valley, frowning over every plain and every sea, wealth beyond calculation has been sunk. Who can tell the immense sums expended in hollowing out the living rock of Gibraltar? Who can calculate the cost of all the Preparations at Woolwich, its 27,000 cannon, and its small arms counted by hundreds of thousands? France alone contains more than one hundred and twenty fortified places; and it is supposed that the yet unfinished fortifications of Paris have cost upward of _fifty millions of dollars_.
