From this place our course continued almost entirely over low hills not exceeding 800 feet above us, until we halted on the margin of a plain bounded to the W. by the Boom, which runs N. and S., the direction being W.N.W. Distance seventeen miles. On our march we met several parties of Shans, Burmese, and Singphos. The path from the village to this is much better, and much more frequented than any of the other parts. Most of the parties were loaded with Serpentine. Noticed en route, both on the plains and on the hills, Teak; in the latter situations many of the specimens were very fine. Another noble Dipterocarpea arborea was observed. I observed Drymaria, Vallaris solanacea, and a Spathodia, which is common on the plains. Teak is remarkable for the smoothness and peculiar appearance of its bark, so that it seems to have had it stripped off.
Gathered on the hills Ulmus and Hyalostemma, the petals of which are united into a tri-partite corolla, a Cyrtandracea in fruit, and an Olacinea, floribus tri-sepalis, appendicibus 6 apice fimbriatis, stam. 3, sepalis oppositis, racemis erectis.
April 5th.—Reached the mines after a march of about four hours; our course was winding, continuing through jungle and small patches of plain, until we reached the base of that part of the Kuwa Boom which we were to cross, and which bore N.W. from the place at which we slept. The ascent was steep in some places, it bore in a N.N.W. direction, principally through a bamboo jungle. From a clear space half way up, we had a fine and pretty view of the hills and plains, especially to the S. and S.E. In the former direction, and distant about fifteen miles, we saw on our return, the Endaw Gyee, but we could not estimate its size or figure; it is evidently however a large sheet of water; the natives say, several miles across. From the summit, we likewise had a fine view of the country to the E.; very few plains were visible in this direction. Nearly due east, and about thirty miles off, was visible Shewe Down Gyee, and this will make Camein nearly due east also, or E. by S. The descent passed through similar jungle, that at the foot being damp. The course continued in a direction varying from S. to W., or rather between these points, through damp jungle. We then ascended another steep hill, but not exceeding 5 or 600 feet in height; descending from this, and passing through low tree and then bamboo jungle, we reached the mines.
The road was, up to the base of Kuwa Boom on the W. side, very good, thence it was in general bad; wet, slippery, much impeded by blocks of serpentine, and foliated limestone (Bayfield) crossing several streams, mountain torrents, the principal one being Sapya Khioung. This takes its name from a spring of water of alkaline properties, which bubbles up sparingly from under its rocky bed, and which must be covered during the rains. The water is clear, of a pure alkaline taste, and is used by the natives as soap.
The mines occupy a valley of a somewhat semi-circular form, bounded on all sides by hills clothed with trees, none being of very great height. The valley passes off to the N. into a ravine, down which the small stream that percolates the valley escapes, and in this at about a coss distant other pits occur. The surface of the valley apparently at one time consisted of low rounded hillocks; it is now much broken, and choked up with the earth and stones that have been thrown up by excavating. The stone is found in the form of more or less rounded boulders imbedded with others, such as quartz, etc. in brickish-yellow or nearly orange clay. The boulders vary much in size. There is no regularity in the pits, which are dug indiscriminately; some have the form of ditches, none exceed 20 feet in depth. They are dug all over the valley, as well as on the base of the hill bounding it to the W. and N.W. We could not obtain any good specimens, nor is there any thing in the spot that repays the visit. No machinery is used, the larger blocks are broken by fire. But that they are of importance in the light of increasing the revenue, is evident, from the fact that B. counted, since we left Camein, 1,100 people on their return, of whom about 700 were Shan Chinese. The loads carried away are in some cases very heavy; the larger pieces are carried on bamboo frames by from two to five men, the lesser on a stout piece of bamboo lashed to and supported on two cross or forked bamboos, the stouter joint resting on the bearer’s neck, the handles of the forks being carried in his hands. The most obvious advantage of this is the ease with which the load may be taken off, when the bearer is fatigued. The revenue yielded last year, B. tells me, was 320 viss of silver, or about 40,000 rupees. The length of the valley from E. to W. is about three quarters of a mile; its breadth varies from 460 to 800 yards.
On our return we boiled water at the Soap spring, which is about 50 feet above the mines, Temp. of the air 80½. 2½ P.M. of boiling water 209. Elevation 1600 feet. And on the top of Kuwa Boom, which is crossed at a comparatively low place, at 4½ P.M. Temp. of the air 76, of boiling water 207. Elevation 2678 feet.
I can say nothing as to the peculiar features of the vegetation, in the woods towards Kuwa Boom. I gathered three Aurantiaceæ; the Olacinea of yesterday is common, a large arborescent Artocarpus fructibus oblongis sub-informibus, sub-acidulis, ¾ uncialibus; Teak rarely; Tonabea, noble specimens occur; on the Kuwa Boom, a large Gordonia arborea, two arborescent Myrtacea, large Mangoes, Bamboo, a Morinda; Magnoliæcea occurs on its western face, as well as the Conifera toxoidea before gathered. Dicksonia and Pladera justicioidea both occur. Dianella nemorosa, etc. The Serpentine is carried from Keoukseik in boats down the Endaw Kioung, thence to Camein, and from whence it goes to Mogam, which is probably the principal mart. Calamus spioris petiolorum uncialibus verticillatis occurs in abundance in all the damp jungle.
We returned in the afternoon to our halting place of yesterday, from which the mines are distant ten miles, four of which occur from the side of Kuwa Boom to the West. The Endaw Gyee is situated on a plain, but it is enclosed by hills on every side except the S.E. Those to the south are very high.
April 6th.—Returned, diverging from the path to the village Keoukseik. Noticed Liriodendron, Æsculus, Achyranthis aspera, Vallaris solanacea, etc.
The village is situated to the S. of the road to the mines; it is close to the Nam Teen, and on a small elevation; it is stockaded. The number of houses is about sixteen; of inhabitants, including children, 120: all the houses, except two, being small. The merchants, etc. employed about the mines, halt on the Nam Theen, which is up to this point navigable for small boats.
