Dr. Hooker, in his travels in the Khasia mountains, mentions Eria, CoeIo-gyne (Wallichi, maculata, and elata), Cymbidium, Dendrobinm, Snnipia, and other beautiful air plants, as growing at the top of the Kolleng rock, flowering profusely; and though freely ex-posed to the sun and wind, dews and frosts, rains and droughts, they were all fresh, bright green, and strong, under very different treatment from that which they are exposed to in the damp, unhealthy, steamy Orchid houses of our English gardens. Vol. ii, 294. "Vanda caerulea grows in profusion, waving its panicles of azure flowers in the wind. As this beautiful Orchid is at present attracting great attention, from its high price, beauty, and difficulty of culture, I shall point out how totally at variance with its native habits is the cultivation thought necessary for it in England.* The dry grassy hills which it inhabits are elevated 3,000 to 4,000 feet; the trees are small, gnarled, and very sparingly leafy, so that the Vanda which grows on their limbs is fully exposed to sun, rain, and wind. There is no moss or lichen on the branches with the Vanda, whose roots sprawl over the rough bark.

The atmosphere is, on the whole, humid, and extremely so during the rains; but there is no damp heat or stagnation of the air, and at the flowering season the temperature ranges between 60° and 80°; there is much sunshine, and both air and bark are dry during the day; in July and August, during the rains, the temperature is a little higher than above, but in winter it falls much lower, and hoar-frost forms on the ground. Now this winter's cold, summer's heat, and autumn's drought, and above all, the constant free exposure to fresh air and the winds of heaven, are what, of all things, we avoid exposing our Orchids to in England. It is under these conditions, however, that all the finer Indian Orchideae grow, of which we found Dendrobium Farmeri, Dalhousianum, Devonianum, Ac, with Vanda caerulea; whilst the most beautiful species of Coelogyne, Cymbidium, Bolbo-phyllum and Cypripedium inhabit cool climates, at elevations above 4,000 feet in Khasia, and as high as 6,000 to 7,000 in Sikkim." - Dodman, in the Gardener's Chronicle.

* We collected seven men's loads of this superb plant for the Royal Gardens, at Kew, but owing to unavoidable accidents and difficulties, few spectmens reached England alive. A gentleman who sent his gardener with us to be shown the locality, was more successful; he sent one man's load to England on commission, and though it arrived in a very poor state, it sold for 800l, the individual plants fetching prices varying from 82. to 102. Had all arrived alive they would have cleared 1000l. An active collector, with the facilities I possessed, might easily clear from 2,000/. to 8,000l, in one season, by the sale of Khasia Orchids.
