For the cultivation of upland padi the site of woods is universally preferred, and the more ancient the woods the better, on account of the superior richness of the soil; the continual fall and rotting of the leaves forming there a bed of vegetable mould, which the open plains do not afford, being exhausted by the powerful operation of the sun's rays and the constant production of a rank grass called lalang. When this grass, common to all the eastern islands, is kept under by frequent mowing or the grazing of cattle (as is the case near the European settlements) its room is supplied by grass of a finer texture. Many suppose that the same identical species of vegetable undergoes this alteration, as no fresh seeds are sown and the substitution uniformly takes place. But this is an evident mistake as the generic characters of the two are essentially different; the one being the Gramen caricosum and the other the Gramen aciculatum described by Rumphius. The former, which grows to the height of five feet, is remarkable for the whiteness and softness of the down or blossom, and the other for the sharpness of its bearded seeds, which prove extremely troublesome to the legs of those who walk among it.* (*Footnote. Gramen hoc (caricosum) totos occupat campos, nudosque colles tam dense et laete germinans, ut e longinquo haberetur campus oryza consitus, tam luxuriose ac fortiter crescit, ut neque hortos neque sylvas evitet, atque tam vehementer prorepit, ut areae vix depurari ac servari possint, licet quotidie deambulentur...Potissimum amat solum flavum arguillosum. (Gramen aciculatum) Usus ejus fere nullus est, sed hic detegendum est taediosum ludibrium, quod quis habet, si quis per campos vel in sylvis procedat, ubi hoc gramen ad vias publicas crescit, quum praetereuntium vestibus, hoc semen quam maxime inhaeret. Rumphius volume 6 book 10 chapters 8 and 13. M. Poivre describes the plains of Madagascar and Java as covered with a long grass which he calls fatak, and which, from the analogy of the countries in other respects, I should suppose to be the lalang; but he praises it as affording excellent pasturage; whereas in Sumatra it is reckoned the worst, and except when very young it is not edible by the largest cattle; for which reason the carters and drovers are in the practice of setting fire to that which grows on the plains by the roadside, that the young shoots which thereupon shoot up, may afterwards supply food to their buffaloes.)
