In the Himalayas, moreover, the warmer aspects are, as a rule, the most fertile; _vice versâ_ in warm localities. Many a garden, which would have done very well on the moderate slopes chosen had _only_ the proper aspects been planted, has been ruined by planting all sides of teelahs or hills indiscriminately. The southern and western slopes of plantations in warm sites are generally very bare of plants. Not strange they should be so, when the power of the reflected rays of the afternoon sun is considered. Again, in cold climates plants cannot thrive on northern aspects, for their great want in such climes is heat and sunshine. Let the above fault, then, be avoided in both cases, for though doubtless a garden is more handy, and looks better in one piece planted all over without any intervening jungle, even patches of jungle look better, and are decidedly cheaper, than bare cultivated hills. Of flat land, after what I have written, I need not add much. It is of two kinds, table and valley land; the former is very rare in Tea districts, at least of any extent, which makes it worth while to plant it. There are two gardens in Chittagong on such flat table land, and they are both doing very well. Table land cannot be too flat, for the natural drainage is so great no stagnant water can lie.[14] Valley land is not good if it is _perfectly_ flat. It will then be subject to inundation and stagnant water. There is nothing that kills the plant so surely and quickly as the latter. Even quite flat valleys can be made sweet by artificial drainage, but to do this a lower level, not too far distant, must exist, and the danger is not quite removed then. Valleys in which no water-course exists, and which slope towards the mouth _alone_, are to be avoided, for the plants near the mouth always get choked with sand. The best valleys are those with a gentle slope both ways, one towards the lowest line of the valley, be it a running water-course, or a dry nullah which carries off rain, the other towards the mouth of the valley. Such valleys drain themselves, or at least very little artificial drainage is necessary. A valley of this kind, with a running stream through it, is _most_ valuable for Tea, and if the other advantages of soil and climate are present it is simply a perfect site. Such however are not frequent. If in such valleys, as is generally the case, the slope from the head to the mouth is enough, the running stream can be “bunded” (shut up) at a high level, and brought along one side at a sufficient elevation to irrigate the whole. I have never seen but one garden in a valley that fulfils all these conditions exactly. It is in Chittagong; the soil is good, labour plentiful, and manure abundant. It ought to do great things, for the possibility of irrigating plants in the dry season (which, as observed, is very trying in Chittagong) will give several extra flushes in the year.
