The succession of crops, next to the facility of irrigation, depends upon the quality of the soil, which in the native provinces is divided by the cultivators into three principal kinds, _tána ládu_, _tána línchad_, and _tána pásir_. The first is the best, consisting of rich vegetable mould, and a certain proportion of sand, and exists chiefly near the banks of large rivers; the second is almost pure clay, and is found in the central plains; and the third is alluvial, and covers the maritime districts. The term _pádas péréng_ is applied to the oblique tracts enriched with a fertile mould, which form the acclivities of hills, and from which the water readily disappears. _Tána ládu_ will bear a constant succession of crops. _Tána línchad_ yields only a single annual crop of rice: during the rainy season the soil constitutes a stiff mud, in which the plants find the requisite moisture and display all their luxuriance; when it is afterwards exposed to the rays of the sun, it bursts into extensive fissures, which admitting the scorching heat by which they were produced, become detrimental to every species of vegetation. Besides the annual crop of rice which is raised on the _sáwah_ lands, a variety of plants are raised upon them as a second or light crop within the same year. Among these are several species of _káchang_ or bean, the cotton plant, the indigo, and a variety of cucumbers, &c. But the more generally useful and profitable vegetables require nearly the same period as the rice, and only yield their increase once in a season: they mostly grow in situations, on which the supply of water can be regulated, and a continued inundation prevented. Among the most important are the _gúdé_, _káchang pénden_, or _káchang chína_, _káchang íju_, _kédéle_, _jágung_ or Indian corn, _jágung chántel_, _jáwa-wút_, _jáli_, _wíjen_, _járak_ or palma christi, _térong_, and _kéntang jáwa_. In _tégal_ lands of high situations a particular method of planting is sometimes practiced, which produces a result similar to a succession of crops. Together with the rice are deposited the seeds of other vegetables, which arrive at maturity at different periods, chiefly after the rice harvest. The most common and useful among these is cotton; and, in some tracts, great quantities of this valuable product is thus obtained, without any exclusive allotment of the soil. Next to this are various leguminous and other plants, which do not interfere with the rice. No less than six or eight kinds of vegetables are sometimes in this manner seen to shoot up promiscuously in a single field.
