in high walls, and cut in two by the rapid Ta Ho. A huddle of palaces, temples, banks lies concealed behind the mud walls that hem in the narrow lanes, for Kalgan has been for many years an important trading centre, and through here passes the traffic across the Gobi Desert. In the dirty, open square crowded with carts are two or three incongruous Western buildings, for the foreigner and his ways have found the town out. Of the small European community, missionaries of different nationalities and Russians of various callings form the largest groups. The energetic British American Tobacco Company also has its representatives here, who were my most courteous hosts during my two days' stay.
Kalgan stands hard-by the Great Wall; here China and Mongolia meet, and the two races mingle in its streets. Nothing now keeps them in or out, but the barrier of a great gulf is there. Behind you lie the depressing heat and the crowded places of the lowlands. Before you is the untainted air, the emptiness of Mongolia. You have turned your back on the walled-in Chinese world, walled houses, walled towns, walled empire; you look out on the great spaces, the freedom of the desert.
