It gives me very great pleasure to observe, in the Gentleman’s Magazine, for February, 1809, that a grass has been discovered in Ireland, called the _fiorin_, which perfectly corresponds with the _doob_ of Hindustan. This invaluable plant stands the severest cold of Iceland, as well as it does the scorching heats of tropical summers. In the latter instance, the verdure certainly disappears; but the root remains unimpaired, and abounds with succulence. I feel no hesitation in asserting, that if the _fiorin_ be what it is described, namely, the _doob_ of Hindostan, it will prove an invaluable acquisition to the British agriculturist. A rich grass that will stand either heat or cold, or immersion for many successive months, cannot fail to abridge our catalogue of Georgic desiderata. The _doob_ is rarely sown in India; but, after being cut below the surface by the tool in common use among grass-cutters, called a _koorpah_, is chopped with a hatchet into pieces about two or three inches in length, when, being mixed with mud, it is plastered on the surface of the plot where it is intended to remain; the plot being previously saturated with water. In a very few days, the _doob_ will be seen to vegetate, especially if care be taken to keep the mud moist for a short time. This grass is likewise well suited for transplanting, by which operation very large plots are sometimes turfed. The stems all throw out roots at every joint that is suffered to touch the ground; but when very thick, and abundant, it is disposed to tower and spindle, not unlike our pink and carnation plants. If set in small tufts, at a foot asunder, they will soon cover the surface.
