On the following day we turned out our Vanda to dress the specimens for travelling, and preserve the flowers for botanical purposes. Of the latter we had 360 panicles, each composed of from six to twenty-one broad pale-blue tesselated flowers, three and a half to four inches across and they formed three piles on the floor of the verandah, each a yard high: what would we not have given to have been able to transport a single panicle to a Chiswick fete! On the 10th of October we sent twenty-four strong mountaineers to Churra, laden with the collections of the previous month; whilst we returned to Nonkreem, and crossing the shoulder of Chillong, passed through the village of Moleem in a north-west direction to the Syong bungalow. From this we again crossed the range to Nunklow and the Bor-panee, and returned by Moflong and the Kala-panee to Churra during the latter part of the month. In November the vegetation above 4000 feet turns wintry and brown, the weather becomes chilly, and though the cold is never great, hoar-frost forms at Churra, and water freezes at Moflong. We prepared to leave as these signs of winter advanced: we had collected upwards of 2,500 species, and for the last few weeks all our diligence, and that of our collectors, had failed to be rewarded by a single novelty. We however procured many species in fruit, and made a collection of upwards of 300 kinds of woods, many of very curious structure. As, however, we projected a trip to Cachar before quitting the neighbourhood, we retained our collectors, giving orders for them to meet us at Chattuc, on our way down the Soormah in December, with their collections, which amounted to 200 men's loads, and for the conveyance of which to Calcutta, Mr. Inglis procured us boats. Before dismissing the subject of the Khasia mountains, it will be well to give a slight sketch of their prominent geographical features, in connection with their geology. The general geological characters of the chain may be summed up in a few words. The nucleus or axis is of highly inclined stratified metamorphic rocks, through which the granite has been protruded, and the basalt and syenite afterwards injected. After extensive denudations of these, the sandstone, coal, and limestone were successively deposited. These are altered and displaced along the southern edge of the range, by black amygdaloidal trap, and have in their turn been extensively denuded; and it is this last operation that has sculptured the range, and given the mountains their present aspect; for the same gneisses, slates, and basalts in other countries, present rugged peaks, domes, or cones, and there is nothing in their composition or arrangement here that explains the tabular or rounded outline they assume, or the uniform level of the spurs into which they rise, or the curious steep sides and flat floors of the valleys which drain them.
