THE ROSIN ỸÇICA. This Paraguayrian rosin is found at the roots of trees under ground, where it flows very copiously from them in the heat of the sun. The Guaranies use it not only for medicinal purposes, but also to tar ships with, when pitch is not to be had. THE TREE ABATI TIMBABỸ. The huge tree abati timbabỹ, in the heat of the sun, sheds a quantity of gum of a golden colour, and clear as the purest crystal, of which the lower orders of Spaniards and the wood Indians make crosses, ear-rings, and beads to hang round the neck, by the following method: they apply hollow moulds, made in the same form, of wood or reeds, to the trunk of the tree, and the gum flowing down into them is hardened by the air, and quickly assumes the shape of crosses, ear-rings, or beads, with admirable exactness; you would swear they were made of crystal. Although as fragile as glass, they can be melted by no moisture. Were European artisans in possession of this gum, they would make knots, buckles, and little images beautifully with it. Might it not possibly contain medicinal properties? No one has hitherto made trial of its virtues. THE CEDAR. The more northerly woods of Tucuman and Paraguay boast of innumerable lofty cedars, which, having exceedingly tall, straight, and large trunks, afford excellent materials for ships, and all sorts of building, as they never feel decay, and last for ever, even under water. No tree which Paraguay produces makes longer or wider beams, which, as they are laboriously hewn, not by a water-machine, but by human hands with a saw, and conveyed in waggons from Tucuman full three hundred leagues, sell very high in the city of Buenos-Ayres, where no woods are to be seen, and whither they are brought from the distant forests of Asumpcion, after a two months' navigation on the river. In Tucuman, indeed, a German lay-brother of our order constructed a machine, by which the saw was moved to the cedars by water underneath the wheel, with a great saving of time and labour; but it was soon after removed and destroyed by the natives, who hate all innovation. Sometimes out of one cedar a very large boat is made, to pull which thirty rowers are hardly sufficient. I do not deny that the tree timboỹ is made into shorter and slenderer planks and boats in Paraguay; but cedars hold the first place, as they excel in the width, height, and straightness of their trunk, in the docility of the materials, and their durability under water. There are two kinds of cedars in Paraguay; the wood of the one is beautifully red, that of the other rather palish; both, however, have a very sweet smell, and in the heat of the sun shed great quantities of gum, which is sometimes white, sometimes red, but always transparent. We used it in the same manner as gum Arabic, to glue things together, and also for polishing; might it not be fit for various medicinal purposes? Water
