never run away, though the plain be close by, and in sight. There is scarcely any Indian town in which you do not see tame emus of this kind. You must know, moreover, that emus differ in size and habits, in different tracts of land: for those that inhabit the plains of Buenos-Ayres and Tucuman, are larger, and have black, white, and grey feathers: those near to the straits of Magellan are smaller and more beautiful; for their white feathers are tipped with black at the extremity, and their black ones, in like manner, terminate in white, and make excellent ornaments for the hats and helmets of Europeans. The higher orders amongst the Spaniards, also, greatly prize skreens made of these feathers. Footnote 1: The American ostrich differs a little from the African. THE TUNCÀ. The tuncà is remarkable on account of its bill, which is as long as its whole body, is as light as paper, of a citron colour, marked at the extremity with a red line, and a black spot, and denticulated at the edges. It has a very long tongue, and rather large eyes, surrounded by a circle of green, and another larger one of yellow. Its feathers are, for the most part, black, except on the neck, which is white, and the tail, which is beautifully red at the extremity; but some are blue instead of black. It is about the size of a pigeon. The tuncà is called by some, the preacher bird, I believe on account of the loudness of its voice. You will scarce ever see this bird in company with any other. It feeds on the ripe seeds of the tree caà, but as those seeds are too glutinous to be digested, it voids them whole, and they produce new trees, and in time woods, to the great profit of the inhabitants. I knew a Yaaucaniga Abipon, who, when going to fight, always tied the huge beak of a tuncà to his nose, in order to render himself more terrible to the enemy. THE CARDINAL. Cardinals are remarkable for the extreme sweetness of their song, and, in my opinion, would far exceed the canary birds of our country, were they able to trill like them. From the shining purple of their feathers they have obtained the name of cardinals. The top of the head alone is adorned with a small black crest, like a little hat. They are about the size of a linnet. They fly in crowds to the most barren fields, where there are more thistles than grass, and are easily caught by boys, who will give you four or five cardinals in exchange for a single needle, in the city of Corrientes. I have seen cardinals resembling the rest in other respects, but much larger, being equal in size to a starling. THE CHOPÌ.
