It is not, however, in a pecuniary point of view alone that the Terai is considered by the Nepaulese as contributing to the prosperity of their dominions; it is looked upon as one of their chief safeguards against invasion. For nine or ten months a disease, denominated by the natives the "Ayul," renders the Terai impassable to man, so deadly are its effects even to the natives of the country. It would appear that might be obviated--if we are to believe the native theory somewhat gravely recorded by Mr. Hamilton (who made a journey through this province with a mission sent by Government in 1803)--by going in search of and killing certain serpents, which are said to poison the atmosphere with their breath. I should be inclined to recommend the cutting down of the jungle in preference to the cutting up of the serpents; and I have little doubt that, were parts of the great forest cleared, and wide roads cut through it, it would cease to be so pestilential a locality as it is at present. In case of a war, there would be no difficulty, even now, in our troops possessing themselves of the whole territory to the foot of the Cheriagotty hills in the cold season; but as we should have to maintain some position throughout the year, the top of those hills themselves would be the only one available, and here, in the heart of an enemy's country, and cut off from all communication with India, the position of the garrison would be anything but enviable. I observed several of the natives of this district afflicted with goitre, and I was informed that cretinism was also prevalent,--a fact which proves clearly the fallacy of the old doctrine that these complaints are attributable to snow-water, for all the water drunk by the inhabitants of the Terai rises in the Cheriagotty hills, on which snow rarely if ever falls. This would be strongly corroborative of the correctness of the idea that malaria is the origin of goitre and cretinism, even if the experiment which has been tried at Interlacken, of building a hospital on the hills, above the influence of the infectious atmosphere in the valley, had not proved completely successful. The camp which was destined to be our headquarters during a few days' shooting was pitched in the plain near the village of Bisoleah, distant about two miles from the borders of the grand jungle. Its appearance was totally different from those already described; two more regiments were here in attendance upon the Minister; the men were all comfortably lodged in grass huts got up for the occasion, and the innumerable host of camp followers, who on the march had been contented with wrapping themselves up in their thick cloths, and sleeping in groups round the various fires, were now engaged in erecting like temporary habitations, forming by these means a grass village of considerable extent.
