616 Notes on the Kasia Hills, and People. [No. 152. 



these remarkable gauges, leave me no room to doubt. In the month of 

 August 1841, during five successive days, thirty inches of rain in the 

 24 hours fell at Cherra ; and the total fall in the month of August 

 was 264 inches ; or, that there may be no mistake, twenty-two feet of 

 rain. The gauge was simply a large glass jar, having a funnel fitted 

 with projecting eaves ; and the water was measured morning and even- 

 ing with a cylinder three inches in depth, of equal diameter with the 

 funnel. 



During the heavy rains above-mentioned, the proportion of the fall by 

 night to that by day, was generally about 18 to 12. 



The formation of the limestone rocks near Cherra gives rise to a 

 curious phenomenon in the disappearance of streams in their hollows. 

 Sometimes a river vanishes in a cleft beneath a high cliff, sometimes 

 falls headlong into a deep circular hollow and is lost to view, reminding 

 one of the gardens of Cambalu, 



Where Alp the sacred river ran 

 By caverns measureless to man 

 Down to a sunless sea." 



There are at least four such instances in the immediate neighbour- 

 hood of Cherra. 



Caves are common, as might be expected. In that a little to the 

 east of Pundua, at a trifling height above the plains, in company with 

 two friends from Cherra, I penetrated 1300 paces, without fatigue or 

 difficulty, and others have I believe gone much further. We were 

 compelled to retreat only by a deficiency of oil. Here, says the tradi- 

 tion, a great army entered, bound for the invasion of China, and were 

 heard of no more. 



Standing on one of the highest points in the station at Cherra, about 

 sunset, I have seen my shadow cast on a distant bank of white fog, that 

 filled the valley to the eastward, an appearance resembling that of the 

 celebrated giants of the Hartz, and the Stockhorn. The figure was 

 surrounded by a circular iris. The heavy fogs that fill the large valley 

 to the east of Cherra, render this a common phenomenon at sunset. It 

 has since been pointed out to me that any one may witness this 

 on a small scale, in going through the grass at sunrise on a dewy
