LIME TREES A TEST OF HUMAN HABITATION.

March \%th. — Left and proceeded down the Kamyoom, or pro- 

 perly Kam-mai-roan, according to Bayfield, in an E. S. E. direction 

 for about seven miles, when we reached the previous halting place 

 of Dr. Bayfield. We passed before arriving at this a small Putar on 

 which were some remains of old habitations ; on it limes abound, 

 and these are a sure test of inhabitation at some previous period. 



The vegetation continues precisely the same as that of the 

 Namtucheek, even to Podostemon Grifnthianum, which I to-day 

 observed for the first time. 



March 14th. — Proceeded on, still keeping for the chief part of our 

 march along the Kammiroan. We left this very soon, and crossed 

 some low hills on which the jungles presented the same features. 

 We left the village Kammiroan to our right. We did not see it, but 

 I believe it consists of only two houses. Passed through one khet, 

 the first cultivated ground we saw after leaving that on the Kam- 

 chick ; then we came on to a few more Putars, in which limes con- 

 tinue abundant. On these I find no less than three species of 

 Rubus ; in those parts on which rice has been cultivated a pretty 

 fringed Hypericum likewise occurs, and these are the most interesting 

 plants that have presented themselves. Our course improved much 

 yesterday ; it extended E. by S., and was rather less than seven 

 miles. Halted at Kha-thung-kyoun, where the Meewoon had halted, 

 and where the Dupha Gam had remained some time previous. The 

 same vegetation occurs, Engelhardtia, Gleichenia major longe scan- 

 dens, Equisetum both species, Euphorbiacea nereifolia, Dicksonia 

 rare, Scleria vaginis alatis, Plantago media, Zizania ciliaris, Melas- 

 toma malabathrica, Lycium arenarum, Duchesnia indica, Mazus rugo- 

 sus, the Suddiya Viburnum, Millingtonia pinnata, Pentaptera, Ery- 

 thrina ; an arboreous Eugenia fol. magnis, abovatis, is however new, 

 and Polypodium Wallichianum which occurred to-day growing on 

 clay-slate. But considering the elevation at which we still remain 

 to be tolerably high, the products both of the vegetable and animal 

 kingdom are comparatively uninteresting. There are more epiphy- 

 tical Orchidese on the south sides of these hills, than the north. Musci 

 and Hepaticse are common, but do not embrace a great amount of 

 species. Machantia asamica is common. Another new tree I found 

 is probably a Careya or Barringtonia ; the young inflorescence is 

 nearly globular, and clothed with imbricated scales. Sedgewickia 

 has disappeared. No tea was seen. There is but little doubt that 

 on hills, the ranges of which rise gradually, the acclimatization
