shrubs, and plants! I shall hardly be able to find my way out of the wood; yet it is best to tarry there awhile till, after having described the medicinal trees, I have enumerated all the rest which are useful in building, or on other accounts worthy of note. THE TAYỸ, OR URUNDEỸ QUEBRACHO. The tayỹ, or tajibo, and the urundeỹ quebracho, either of a red, or pale colour, excel in hardness and size; both trees are called by the Spaniards _quebracho_, or _quebrahacho_, because, unless dexterously cut by a skilful woodman, or carpenter, they break the axe at the first blow, being as hard as iron; for _hacha_ means an axe, and _quebrar_ to break. The quebracho colorado, when covered with its bark, is red. As soon as it is cut down and worked upon, the rosin in which it abounds is melted by the hot air, and flowing to the exterior parts of the wood, gives it a red hue, and causes it to shine like porphyry. The Guaranies burn pieces of the tree tayỹ, receive the smoke or soot arising from them into a clean dish, and by pouring hot water upon it, convert it into ink, which, mixed with gum and sugar, is by no means to be despised. THE LAPACHO. The lapacho is remarkable for the hardness and heaviness of its wood, and is particularly useful in making the mills for squeezing the sugar cane, olives, and other things, and also for wheels of waggons. THE VIRARÒ. The virarò affords white, not very hard, but extremely durable materials. THE ESPINILLO. The espinillo has very strong wood, but its indocility renders it fitter for the fire than for carpenter's work. THE NETERGE. Of the pith of the neterge very strong spears or pikes are made. This tree is remarkable for the width and height of its trunk. Its leaves, which are like oblong thorns, point towards the ground. For fruit, it bears pods or bags, which are about a span long, and have a balsamic odour. The pith of this tree equals iron in hardness, and is of a violet colour, which however changes to black, after the spears made of this wood have been rubbed some time by the hand. THE ỸBARÔ. The large tree ỹbarô bears black, shining berries, about the size of filberts, which are pierced in the middle, and made into rosaries. THE ÇEVIL. The çevil produces bark for dressing hides, together with certain pods, which the savage Indians used formerly to burn, inhaling the smoke into their mouth, nose, and whole body, which rendered them drunk, mad, and for some time furious. THE SEIBO.
