Recent exploration shows that this wall is about eighteen hundred miles in length, stretching from a point on the seashore somewhat east of Peking, to the northern frontier of Tibet.

Roughly speaking, it is twenty-two feet in height by twenty feet in breadth; at intervals of a hundred yards are towers forty feet high, the whole being built originally of brick, of which in some parts but mere traces now remain.

Nor is this the only great wall; ruins of other walls on a considerable scale have lately been brought to light, the object of all being one and the same--to keep back the marauding Tartars.
Over the length and breadth of their boundless empire, with all its varying climates and inhabitants, the Chinese people are free to travel, for business or pleasure, at their own sweet will, and to take up their abode at any spot without let or hindrance.

No passports are required; neither is any ordinary citizen obliged to possess other papers of identification.

Chinese inns are not exposed to the annoyance of domicilary visits with reference to their clients for the time being; and so long as the latter pay their way, and refrain from molesting others, they will usually be free from molestation themselves.
