"If any one part of the broad expanse of the continent of Asia could be heated so as to draw air from the Arabian Sea and the Indian Ocean during the summer, it would be that part which lies between Hindoostan and the Lake of Aral, including the region between the Valley of the Oxus and Persia, and the land of this part, unlike Hindoostan, is not screened from the sun by thick vapors. But what says Burnes respecting the winds of this part? Why, that about the latter end of June, though the thermometer was at 103 deg. in the day, 'In this country a steady wind generally blows from the north.' And on the 23d of August, after having passed the Oxus--'The heat of the sand rose to 150 deg., and that of the atmosphere exceeded 100 deg., but the wind blew steadily, nor do I believe that it would be possible to traverse this tract in summer if it ceased to blow. The steady manner in which it comes from one direction is remarkable in this inland country.' Again--'The air itself was not disturbed but by the usual north wind that blows steadily in this desert.' And he has many other similar passages." Here there is a vast tract of country south of 35 deg. which has a temperature often of 103 deg., and does not reverse the trade and create a monsoon. How utterly unphilosophical, then, to attribute the monsoons to Cobi because they "obey the stronger force!" or to attribute them to it at all. 4th. The monsoons can not be _traced from_ the Malabar coast _to Cobi_. They do not exist on the south-west of Cobi and near it, where they should in greatest force, and there is no connection, in fact, shown between them. They do not often extend more than twenty-five miles inland, or to the east of the Ghauts. There are no corresponding intervening monsoons crossing India to the mountains--none over the mountains and table lands--none under the northern lee of the mountains--nor, in short, on the whole track, nor any S. W. winds except such as naturally belong to the action of the curving counter-trade.
