2. Railways are to be constructed and used as directed by the legislative acts creating them.
4. For most purposes a railroad is a public highway, but it may be the subject of private property, and it has been held that it may be sold as such, unless the sale be forbidden by the legislature; not the franchise, but the land constituting the road. 5 Iredell, 297. In. general, however, the public can only have a right of way for it is not essential that the public should enjoy the land itself, namely, its treasures, minerals, and the like, as these would add nothing to the convenience of the public.
5. Rail-road companies, like all other principals, are liable for the acts of their agents, while in their employ, but they can not be made responsible for accidents which could not be avoided. 2 Iredell, 234; 2 McMullan, 403.
