the great fall at Moosmai becomes really beautiful, the water shooting over the precipice and falling into a bason about 150 feet below.  By a succession of these falls, although of more limited height, it at length reaches the bottom of the valley.  It is only on the precipices about the fall that the Chamaerops appears to grow; at the foot of a precipice a little to the right (going from Churra,) a tree fern grows, which I have Wallich’s authority for stating to be Polypod giganteum, a fern which occurred at Mahadeb, and which I have seen in somewhat similar situations at Mergui.  All my excursions have been confined to this valley and to the water-courses immediately around Churra; once only have I quitted the table-land and proceeded to Maamloo, and yet in this very limited space the profusion of objects has been such as to enable me only to embrace a very limited proportion.  The above excursion proved very rich.  About half way to Maamloo I discovered a solitary tree fern (Alsophila Brunoniana,) and to the left, and up the broken sides of the calcareous cliffs that occur here and between Maamloo and Moosmai, a group of several magnificent specimens, of which on the succeeding day we brought home three.  We saw none above 30 feet, although the specimen in the British Museum from these hills measures 45.  Their axis is of small diameter, and is nearly cylindrical, the vascular fascicles being disposed in covered bundles, often assuming the form of a UU near the circumference of the very dense cellular tissue of which the axis is chiefly composed.  Towards the base it is enveloped in an oblique dense mass of intermottled rigid fibres (roots) which, as they are developed in the greatest extent, the nearer they approach the base, give the trunk a conical form.  Their growth is essentially endogenous, and will probably be found when examined aborigine to approximate to that of Cycadeae, although these last are of a more exogenous than endogenous nature.  Nothing however is known of the growth of Palms, Cycadeae, or tree ferns.  I have above alluded to the calcareous rocks or cliffs; these are of the same formation with those that occur so abundantly on the Tenasserim coast, although they are much more rich in vegetation.  These I first saw at Terrya Ghat; like those of Burmah they abound in caves, and assume the most varied and picturesque forms; they appear to be the head quarters of Cyrthandraceae, of which we found a noble species with the flower of a Martynia growing among the tree-ferns.  They are very rich in ferns and mosses, of which last near the tree-ferns I gathered four species of four genera without moving a foot.  The cliffs in which, or at the foot of which the coal is found, bound the Churra cantonments to the Westward.  These are chiefly calcareous.  The entrance to Churra lies between this and the precipice at Moosmai.  Very few animals of any description are to be seen about Churra.  I have seen one small species of deer,
