Manoa."* (* Cayley's Life of Raleigh volume 1 pages 159, 236 and 283. Masham in the third voyage of Raleigh (1596) repeats these accounts of the Lake Rupunuwini.) Hondius has given a curious plate of this portage; and, as the mouth of the Carony was then supposed to be in latitude 4 degrees (instead of 8 degrees 8 minutes), the portage of Parima was placed close to the equator. At the same period the Viapoco (Oyapoc) and the Rio Cayenne (Maroni?) were made to issue from this lake Parima. The same name being given by the Caribs to the western branch of the Rio Branco has perhaps contributed as much to the imaginary enlargement of the lake Amucu, as the inundations of the various tributary streams of the Uraricuera, from the confluence of the Tacutu to the Valle de la Inundacion. We have shown above that the Spaniards took the Rio Paragua, or Parava, which falls into the Carony, for a lake, because the word parava signifies sea, lake, river. Parima seems also to denote vaguely great water; for the root par is found in the Carib words that designate rivers, pools, lakes, and the ocean.* (* In Persian the root water (ab) is found also in lake (abdan). For other etymologies of the words Parima and Manoa see Gili volume 1 pages 81 and 141; and Gumilla volume 1 page 403.) In Arabic and in Persian, bahr and deria are also applied at the same time to the sea, to lakes, and to rivers; and this practice, common to many nations in both worlds, has, on our ancient maps, converted lakes into rivers and rivers into lakes. In support of what I here advance, I shall appeal to very respectable testimony, that of Father Caulin. "When I inquired of the Indians," says this missionary, who sojourned longer than I on the banks of the Lower Orinoco, "what Parima was, they answered that it was nothing more than a river that issued from a chain of mountains, the opposite side of which furnished waters to the Essequibo." Caulin, knowing nothing of lake Amucu, attributes the erroneous opinion of the existence of an inland sea solely to the inundations of the plains (a las inundaciones dilatadas por los bajos del pais). According to him, the mistakes of geographers arise from the vexatious circumstance of all the rivers of Guiana having different names at their mouths and near their sources. "I have no doubt," he adds, "that one of the upper branches of the Rio Branco is that very Rio Parima which the Spaniards have taken for a lake (a quien suponian laguna)." Such are the opinions which the historiographer of the Expedition of the Boundaries had formed on the spot. He could not expect that La Cruz and Surville, mingling old hypotheses with accurate ideas, would reproduce on their maps the Mar Dorado or Mar Blanco. Thus, notwithstanding the numerous proofs which I have furnished since my return from America, of the non-existence of an inland sea the origin of the Orinoco, a map has been published in my name,* on which the Laguna Parima figures anew.
