Passing the confluence of the Nam Hou, they came upon the cavern of Pak Hou, which the Buddhist priests have covered with religious decoration, and adorned with the gifts of munificent pilgrims. Thence they proceeded to Ban Tanoun; and from Ban Tanoun to Xieng Khong, the second in importance of the towns of the great province of Muong Nan. There they experienced some difficulty in obtaining permission to enter the Burmese territory; and, moreover, they found that they had nearly reached the limit of the navigable portion of the river. Few are the obstacles, however, which cannot be conquered by resolution and energy; and on the 14th of June the expedition left Xieng Khong in six light boats, drawing but little water, and continued the ascent of the river, which here bends to the westward, and flows across an apparently boundless plain. It is crossed near the town or village by a graceful but slender bridge of bamboo, from which may be obtained a charming view of its graceful sweep through a luxuriance of tropical vegetation. * * * * * ~AT MUONG LIM.~ ~A CAUCASIAN PEOPLE.~ At Muong Lim the expedition were compelled to abandon their boats. Its members found themselves there in the midst of a population differing in race from any they had previously met with. They seem, these Mou-tsen, to be of Caucasian origin. Their costume is very complicated, and even tasteful; and the tinsel and embroidery with which they cover their persons gives them a certain resemblance to the inhabitants of some parts of Brittany. The head-gear of the women has, at all events, the merit of originality. It consists of a series of rings of bamboo, covered with plaited straw, and fastened on the top of the head. The brim of this kind of hat is enriched over the forehead with silver balls; above are two rows of pearl-white glass beads; on the left side depends a tuft of white and red cotton thread, from which issues a loop formed of strings of many-coloured pearls. This coiffure, which is capable of infinite modifications, is completed with an abundance of leaves and flowers. The women also wear a tight-fitting bodice, the sleeves and edges of which are trimmed with pearls, and a short petticoat reaching to the knee. The legs are wrapped round with leggings, which begin at the ankle, and cover the whole of the calf. These leggings, too, are ornamented with a row of pearls about half-way up. The toilette is completed by ear-rings of coloured beads or balls of blown silver, bracelets, belts, collars, and shoulder-belts crossed over the bosom. As for the men, they wear the usual turban, loose short pantaloons, and a waistcoat with silver buttons. With both sexes a necessary addition to the attire is a kind of cloak or mantle of leaves, in shape like a book half-open, which is fastened to the neck, and in rainy weather is brought up over the head like a loose cover. The women, when carrying burdens, add to their already complex
