The principal routes between the north and the south are here given, as also the intermediate places, together with those inland most frequented by the traveller and the man of business, and the distances carefully noted as they diverge, in their various directions. Beside the four annexed routes to New York, there are several that lead to favorite watering places, and other points attractive to travellers of leisure, which it would be quite impracticable to lay down in a work of this kind. They can always obtain information of these resorts, from intelligent companions on the road, that will prevent their deviating much from the point they wish to attain. The distances on the river have been corrected agreeably to the latest survey. The other routes conform to the most approved authorities; and, frequently, have been corrected by personal observation, with the utmost care and attention.
