The great extent of railway communication in America in proportion to its population must necessarily excite much admiration. If we take the present population of the United States at 24,000,000, and the railways in operation at 10,000 miles, it will follow that in round numbers there is one mile of railway for every 2,400 inhabitants. Now, in the United Kingdom there are at present in operation 6,500 miles of railway, and if we take the population at 30,000,000, it will appear that there is a mile of railway for every 4,615 inhabitants. It appears, therefore, that in proportion to the population the length of railways in the United States is greater than in the United Kingdom in the ratio of 46 to 24. On the American railways passengers are not differently classed or received at different rates of fare as on those of Europe. There is but one class and one fare. The only distinction observable arises from color. The colored population, whether emancipated or not, are generally excluded from the vehicles provided for the whites. Such travellers are but few, and are usually accommodated either in the luggage van or in the carriage with the guard or conductor. But little merchandise is transported, the cost of transport being greater than goods in general are capable of paying; nevertheless, a tariff regulated by weight alone, without distinction of classes, is fixed for merchandise. Although Cuba is not yet _annexed_ to the United States, its local proximity here suggests some notice of a line of railway which traverses that island, forming a communication between the city of Havana and the centre of the island. This is an excellently constructed road, and capitally worked by British engines, British engineers, and British coals. The impressions produced in passing along this line of railway, though different from those already noticed in the forests of the far west, is not less remarkable. We are here transported at 30 miles an hour by an engine from Newcastle, driven by an engineer from Manchester, and propelled by fuel from Liverpool, through fields yellow with pineapples, through groves of plantain and cocoa-nut, and along roads inclosed by hedge-rows of ripe oranges. To what extent this extraordinary rapidity of advancement made by the United States in its inland communications is observable in other departments will be seen by the following table, exhibiting a comparative statement of those _data_, derived from official sources, which indicate the social and commercial condition of a people through a period which forms but a small stage in the life of a nation:
