There are two species of locusts, which come in clouds, darkening the air, from the desert: the _pharka_ and the _tiri_ are their names;[4.25.18] the first is the great enemy of our incipient prosperity. I observed a colony some time ago proceeding eastward with a rustling, rushing sound, like a distant torrent, or the wind in a forest at the fall of the leaf. We have thus to struggle against natural and artificial obstacles to the rising energies of the country; and dread of the _pharkas_ deters speculators [667] from renting this fertile tract, which almost entirely belongs to the fisc. Its natural fertility cannot be better demonstrated than in recording the success of an experiment, which produced five crops, from the same piece of ground, within thirteen months. It must, however, be understood that two of these are species of millet, which are cut in six weeks from the time of sowing. A patch of ground, for which the cultivator pays six rupees rent, will produce sugar-cane six hundred rupees in value: but the labour and expense of cultivation are heavy, and cupidity too often deprives the husbandman of the greater share of the fruits, ninety rupees having been taken in arbitrary taxes, besides his original rent. The air of this elevated region gave vigour to the limbs, and appetite to the disordered stomach. There was an exhilarating _fraîcheur_, which made us quite frantic; the transition being from 96° of Fahrenheit to English summer heat. We breakfasted in a verdant spot under the shade of a noble fig-tree fanned by the cool breezes from the mountains.
