Mr. S. B. Buckley has communicated to Silliman's Journal a very interesting paper, from which we make the following extracts. Of the Pyrularia old/era noticed in this journal lately, he says: "Among several shrubs which we obtained for cultivation, the Pyrularia oleifera or oil-nut is peculiarly interesting. It grows to the height of from five to ten feet, and bears a pear-shaped fruit little more than an inch in diameter, which is so oily that it will burn like a candle if a wick be drawn through it. Squirrels are fond of it, and cattle have a great liking for the young branches and leaves of the Pyrularia. Last spring we saw an abundance of it in the edge of some woods fenced into a wheat field, and in October we again went there after the fruit; but the harvest was past, - the field had been pastured with cattle, which had destroyed nearly all of the Pyrularia. Hence it has already become rare, and the general occupancy of the mountains with herds of cattle and flocks of sheep would soon destroy it entirely. Mr. Durand, of Philadelphia, thinks that the oil expressed from it is superior to the best olive oil.

Our specimens of the Pyrularia have been planted at Philadelphia, New York, and at the botanic garden of Cambridge, near Boston, and also some of them have been sent to Paris to the Acclimating Society Of France, whose object is to acclimate useful trees, shrubs, and plants".
