Glance now at the _Navy_ of European Christendom. The Royal Navy of Great Britain consists at present of 557 ships of all classes; but deducting such as are used for convict ships, floating chapels, coal depots, the efficient navy consists of 88 sail 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 there were in commission in 1839, 190 ships, carrying in all 4,202 guns. The number of hands employed was 34,465. The Navy of France, though not comparable in size 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 190 smaller vessels; and the amount of crews in 1839, was 20,317. The Russian Navy consists of two large fleets in the Gulf of Finland and the Black Sea; but the exact amount of their force and their available resources has been a subject of dispute among naval men and politicians. Some idea of the size of the navy may be derived from the number of hands employed. The crews of the Baltic fleet amounted in 1837, to not less than 30,800 men; and those of the fleet in the Black Sea to 19,800, or altogether 50,600. The Austrian Navy consisted in 1837, of 8 ships of the line, 8 frigates, 4 sloops, 6 brigs, 7 schooners or galleys, and a number of smaller vessels; the number of men in its service in 1839, was 4,547. The Navy of Denmark consisted at the close of 1837, of 7 ships of the line, 7 frigates, 5 sloops, 6 brigs, 3 schooners, 5 cutters, 58 gun-boats, 6 gun-rafts, and 3 bomb-vessels, requiring about 6,500 men to man them. The Navy of Sweden and Norway consisted recently of 238 gun-boats, 11 ships of the line, 8 frigates, 4 corvettes, 6 brigs, with several smaller vessels. The Navy of Greece consists of 32 ships of war, carrying 190 guns, and 2,400 men. The Navy of Holland in 1839 consisted of 8 ships of the line, 21 frigates, 15 corvettes, 21 brigs, and 95 gun-boats. Of the immense cost of all these mighty Preparations for War, it is impossible to give any accurate idea. But we may lament that means, so gigantic, should be applied by European Christendom to the erection in time of Peace, of such superfluous wooden walls! In the _Fortifications and Arsenals_ of Europe, crowning every height, commanding every valley, and frowning over every plain and every sea, wealth beyond calculation has been sunk. Who can tell the immense sums that have been expended in hollowing out, for the purposes of War, the living rock of Gibraltar? Who can calculate the cost of all the Preparations at Woolwich, its 27,000 cannons, and its hundreds of thousands of small arms? France alone contains upward of 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_!
