Rail Road Travelling. — It appears from a paragraph in the Gazette, that the amount received by the Baltimore and Ohio Rail Road Company from persons travelling between Baltimore and Frederick during the month of July last, exceeded Eight Thousand Dollars. A gentleman who took an excursion on the Rail Road a few days ago, informs us that there were between three and four hundred persons in the two trains that ran to Ellicott’s Mills in the afternoon. They were drawn by new locomotive engines, of American construction, using Anthracite coal for fuel, and working with a degree of ease, power, and swiftness, fully, equal to the best English engines. The passage by each other, in opposite directions, of the trains of carriages, he described as being but the work of an instant, leaving on the minds of the passengers a strong and lively impression of the wonderful facilities afforded by this mode of conveyance.
