Interesting Geographical Notice. Baron Humboldt, in his “ Eſſai politique ſur le Royaume de la Nouvelle Eſpagne,” has deſcribed nine points of communication between the Atlantic and Pacific Oceans. It has not been yet generally known that a communication by water has actually exiſted. Of theſe the 7th is peculiarly intereſting: “In the interior of the province of Choto, the ſmall Ravin de la Raſpadura unites the neighboring ſources of the Rio de Noanama, called, alſo, Rio San Juan, and the little river Quito. This river, united with the Rio Andageda and the Rio Zitara, forms the Rio d’ Ataro, which flows into the Sea of the Antilles, (Caribbean Sea) and the Rio San Juan falls into the South Sea. An enterprizing monk, (the curate of the village of Novita,) with the aid of his flock, (ſeſ paroieſſiens,) dug a ſmall canal in the Ravin de la Raſpadura. By this canal which is navigable during the periods of abundant rains, boats, laden with Cacao, have paſſed from one ſea to the other. Here then is a communication, which has exiſted ſince 1788, and of which the Europeans know nothing. This canal of Raſpadura unites, on the coaſts of the two oceans, two points which are ſeventy five leagues apart” Eſſai Politique, liv. 1 ch. 2. This canal, effected by the enterprizing monk, is nearly in the latitude of Cape Corientes, or about ſix degrees fortyfive minutes north and about three degrees eaſt of the Capitol—Z.—Nat Int.
