This small tree (Catoglionia lobata), known in Peru under the name of Pinon-cello and cultivated about Sureo, Huacho, and Sambageque, also growing wild in great abundance in those regions, it has been ascertained yields a valuable oil well adapted to the purposes of illumination. Its bean-like fruit, or seeds, when roasted, have an agreeable flavor, preferable to that of the Olive. When eaten raw, the etherial oil generated between the kernel and the outer akin is a strong cathartic, the effects of which can only be counteracted by drinking cold water. It has been ascertained that the seeds will grow in Baltimore; and, doubtless plantations of this tree might be formed in many parts of the South, from which vast quantities of oil might be produced, and thus add another link to the great chain of our national wealth. We understand that the Patent Office has taken measures to procure some of the seeds of this tree for trial in the South and Southwest - Washington Union, May 10th.

A New Oil Plant #1

The small plant (Castiglionia lobata,) known in Peru under the name of "Pionncello," and cultivated about Surco, Huacho, and Sambageque, also growing wild in considerable abundance in those regions, it has been ascertained, yields a valuable oil, well adapted to the purposes of illumination. Its bean like fruit, or seeds, when roasted, have an agreeable flavor, preferable to that of the olive. When eaten raw, the etherial oil generated between the kernel and the outer skin is a strong cathartic, the effects of which can only be counteracted by drinking cold water. It has been ascertained that the seeds will grow in Baltimore; and, doubtless, plantations of this tree might be formed in many parts of the South, from which vast quantities of oil might be produced, and thus add another link to the great chain of our national wealth. The Patent Office has taken measures to procure some of the seeds of this tree for trial in the South and South-west. - Bath Sun.

The newspaper press generally pays so little attention to scientific affairs, that it is quite refreshing to meet with a paragraph like the above, which can be understood. The plant alluded to, is better known to gardeners under the name of Jatropha, or Curcas, its original name. It is very closely allied to the Ricinus, or Castor oil plant so common in gardens, and like that plant, the oil produced by it is of the most violently purging character. The whole family of plants, to which the present subject belongs, Eupkorbiacles, is celebrated for their oily and gummy properties, and many of them might be made of more service in the economic arts, than they even are at present. Plants of it might be obtained from some of the English old Botanic gardens.

A correspondent in the Pacific communicates for the Horticulturist the following information: -

"In the province of Piura, Peru, grows wild a bush or plant, said to resemble the Palma Christi. It is known commonly by the name Pifion. A countryman of ours, Alfred Duvall, Esq., has produced from the seeds of this plant an oil, which for lubricating, as well as for illuminating purposes, is fully equal to, if not superior to the best spermaceti oil, at least, such is his opinion, after sufficient experiment. He is about erecting the necessary machinery, and making arrangements to collect the seeds, in ample quantity, for the purpose of producing the oil in sufficient amount to supply the market, at a price very much less than that of any other oil of equal quality".
