and party, who had just arrived, at the other end of the village. The route was for 

 several miles in the bed of the Kadeng choung. Here I passed the laterite stratum (from 

 wheiic^ the big rocks at Kway-wa-Klieiug came from) broken through by the chouuf. The 

 following is a section of this remarkable occurrence of laterite. ""

This is the first instance that I met with true diluvial laterite within the Yomah 

 sandstone hills. It is probably an ancient pebbly river-bed. The upper layers consist of so 

 decomposed a mass, that it is not easy to say whether it is really decomposed sandstone or sand 

 consolidating into sandstone. Any how it is stratified and the ferruginous matter has 

 penetrated into the lower stratum. 



All the ridges were covered with upper mixed forests, while the alluvial deposits of the 

 choung bore a sort of savannah forest of hilly-character, with coarse wild sugarcane and such 

 riparian trees as didu {Bombrix Malab iric:im) Ye-Kathit (Eri/thrina lit/iosperma), Bischojfia 

 Javanica, ma-u [Sarcocephalus cordatus), ye tapan {Ficus glomerc.ta and F. Chittagonga) and 

 others. 



27//* Janu'iry, 1871. Camp halted at Yaitho. I made two excursions, one to the ridges 

 to the right side of the Yaitho choung with upper-mixed forest ; the other over high ridges 

 on the opposite banks presenting the same kind of forest, in wliich, however, the bamboo trees 

 had flowered a few years ago where now, on this account, the dead bamboos render an 

 advance almost impossible. It took me fully 3 hours to cut a way of only 2 miles and of 

 this distance half the way lay through deserted tounggyas. 



The following is the list of trees, etc., I met with in the upper mixed forests on the 

 ridges to the right, summed up just as they came into sight : Lepisiinthes montana, a single 

 treelet in a damp gorge, Kaboung (Stnjchnos nux vomica), pyenkadu {Xi/Ha dolabri/ormis), 

 Kyattoun wa {Bambxm Brandmana), Barleria polytricha, Kyun na lin {Premna tomentosa)

 Leucas up., SlrobUanthcs scabra, Aciocephahis capitatus, Blumea lacem ? a large Flemingia, 

 Desmodium triquetruin with smooth pods, Glcrodendron serratum, Kimba-lin {Antidesma 

 Buniaa) Desmodium rccurvatum ?, Lygodium scandeiifi, Limonia alternifolia, baup noe {Bufea 

 superba and Spatliolobus Roxburghii), damagne {Millcttia exfenun), Crotalaria sp., with simple 

 leaves, Melidcrcn plebeja, tamaklia noe (Congea tomentosa), Ccntotheca lappacea, Lepidagathis
