14th. Arrived at Ayer Grau or Abu, a small river, within a yard or two of which we saw columns of smoke issuing from the earth, where there were hot springs of water bubbling up in a number of places. The stream was quite warm for several yards, and the ground and stones were so hot that there was no standing on them for any length of time. The large pieces of quartz, pumice, and other stones apparently burnt, induce us to suppose there must have formerly been a volcano at this spot, which is a deep vale, surrounded by high hills. Arrived much fatigued at Tanjong Agung, where the head dupati received us in his best style. COCONUTS. He seemed to know more of European customs and manners than those whom we have hitherto met with, and here, for the first time since quitting the Ipu district, we got coconuts, which he presented to us. CASSIA. We saw numbers of cassia-trees in our march today. The bark, which the natives brought us in quantities, is sweet, but thick and coarse, and much inferior to cinnamon. This is the last and best fortified village in the Serampei country, bordering on the forests between that and Anak-Sungei. PECULIAR REGULATION. They have a custom here of never allowing any animal to be killed in any part of the village but the balei or town hall, unless the person wishing to do otherwise consents to pay a fine of one fathom of cotton cloth to the priest for his permission. The old dupati told us there had been formerly a great deal of sickness and bloodshed in the village, and it had been predicted that, unless this custom were complied with, the like would happen again. We paid the fine, had the prayers of the priest, and killed our goats where and as we pleased. 16th. Marched in a south-westerly direction, and, after passing many steep hills, reached the lesser Ayer Dikit River, which we crossed, and built our huts on its western bank. 17th. Marched in a west, and afterwards a south, direction; the roads, in consequence of the rain ceasing today, tolerably dry and good, but over high hills. Arrived at Ayer Prikan, and encamped on its western bank; its course north and south over a rough, stony bed; very rapid, and about thirty yards across, at the foot of Bukit Lintang. Saw today abundance of cassia-trees. 18th. Proceeded to ascend Bukit Lintang, which in the first part was excessively steep and fatiguing; our route north and north-west when descending, south-south-west. Arrived at one of the sources of the Sungei-ipu. Descending still farther we reached a small spring where we built our huts. 19th. On our march this day we were gratified by the receipt of letters from our friends at Bencoolen, by the way of Moco-moco, from whence the Resident, Mr. Russell, sent us a supply of wine and other refreshments, which we had not tasted for fourteen days. Our course lay along the banks of the Sungei-ipu, and we arrived at huts prepared for us by Mr. Russell. 20th. At one time our guide lost the
