In the maritime portions of the country the year has two seasons,—the dry and the wet. The latter always begins about the tenth of May, with showers gradually growing more frequent, for several weeks. It afterwards rains almost daily until about the middle of September, when it as gradually goes off, and in the course of a month entirely ceases. During this time from one hundred and fifty to two hundred inches of water fall. This is the only time when the country is unhealthy for foreigners, and even then, there are many places where persons may reside with impunity. In other parts of the country there are three seasons. In the highest and wildest provinces there are severe winters. Amidst these mountain-passes rises the great and sacred river Irawadi, named from the elephant of Indra, which, like the stream of history, flows down from amidst obscurity and uncertainty. The sources of the Irawadi are yet undiscovered; but Lieutenant Wilcox, who explored a considerable portion of Burmah, was informed, that they were not far distant from that of the Burampooter, or Brahmapootra. It has a course of more than twelve hundred miles to the sea; and passing through the whole of the empire, it falls into the Gulf of Martaban, by a great number of mouths, in the kingdom of Pegu. Its breadth varies from one to three, and even five miles in various parts of its course. How different from its narrowest width of eighty yards, at about forty miles from its supposed source. The river issues from the mountains, and enters an extensive valley, occupied by the tribes of the Khunoongs. At this early point of its course, the country is perfectly level, and is partly cultivated, while the remainder is studded with small woods of bamboo. The Irawadi is little more than eighty yards broad at the town of Manchee, and is quite fordable. The plain of Manchee is 1,855 feet above the level of the sea. After passing through this plain, it runs through countries very little blown to Europeans, for about 120 miles. Rugged mountain-chains here form the banks of the river, sometimes diversified by a plain of some extent. Bamoo is the first place of consequence on the river after Manchee, and is about 350 miles distant from the latter town. The level of the river falls 1,300 feet between the two places. At some distance from Bamoo, near a village called Kauntoun, the river suddenly turns westwards but soon runs south-west again. A little above Hentha it takes a direction due south, so continuing to Amarapura. From Bamoo to Amarapura the country is only navigable for small boats.
