The communication with Panompen, the Cambodian capital, is by boat down the river and crossing to the lower end of the lake, then by the river which connects the lake with the Mekong. From Siamrap to Panompen requires six days by boat. Half a dozen miles north of Siamrap, in the midst of a lonely forest, we come upon the celebrated ruins of Nagkon Thom, or Angkor the Great, and Nagkon Wat, the City of Monasteries, is a few miles off. The city ruins to-day are little more than piles of stone among the jungles. The outer wall, built of immense volcanic rocks, is best preserved. The natives say an entire day is necessary to circumambulate the walls. A mutilated statue of the traditional leper king is seated on a stone platform near the gate of the inner wall, protected by a grass thatch. The pedestal has an ancient inscription on stone. The ruins are in the charge of a provincial officer, who lives in a lodge near the palace. There are some old towers still standing. Some thirty miles distant are the Richi Mountains, said to contain the quarries from which the supply of stone was obtained. A broad causeway, still in serviceable repair, leads to the foot of these hills. Mr. Thomson tried to go there, but the thick jungle made it impossible to penetrate to the quarries even on elephants, although the officer who accompanied him made a series of offerings at several ruined shrines in order to propitiate the malignant spirits supposed to infest these wilds. Concerning Angkor the Great ancient tradition speaks in most extravagant terms, as being of “great extent, with miles of royal treasure-houses, thousands of war-elephants, millions of foot-soldiers and innumerable tributary princes.” A road through the forest connects this once royal city with Nagkon Wat. Along this road a side-path leads to an observatory, overgrown with shrubs and vines, standing on a terraced hill and commanding a wide view of the surrounding region.
