With another year a still completer expedition was fitted out, Bruno Heceta being commander and Francisco de la Bodega y Quadra, second in command. This voyage was the most important and interesting thus far in the history of the Columbia River exploration. For Heceta actually found the Great River, so long sought and so constantly eluding discovery. On June 10, 1775, Heceta passed Cape Mendocino, and entered a small bay just northward. There he entered into friendly relations with the natives and took solemn possession of the country in the name of His Catholic Majesty of Spain. Sailing thence northward, he again touched land just south of the Straits of Fuca, but there he met disaster at the ill-omened point subsequently named Destruction Island. For there his boat landing for exploration was set upon by the savage inhabitants, and the entire boat-load murdered. Moving southward again, on August 15th, in latitude 46 degrees 10 minutes, Heceta found himself abreast of some great river. Deciding that this must be indeed the mysterious Strait of Fuca, or the long concealed river of the other ancient navigators, he made two efforts to enter, but the powerful current and uncertain depths deterred him, and he at last gave up the effort and bore away for Monterey. Three additional names were bestowed upon the River at this time. Thinking the entrance a bay, Heceta named it, in honour of the day, Ensenada de Asuncion. Later it was more commonly known as Ensenada de Heceta, while the Spanish charts designated the river as Rio de San Roque. The name of Cabo de Frondoso (Leafy Cape) was bestowed upon the low promontory on the south, now known as Point Adams, while upon the picturesque headland on the north which we now designate as Cape Hancock, the devout Spaniards conferred the name of Cabo de San Roque, August 16th being the day sacred to that saint. The original account given by Heceta is so interesting that we insert it here: On the 17th day of August I sailed along the coast to the 46th degree, and observed that from the latitude 47 degrees 4 minutes to that of 46 degrees 10 minutes, it runs in the angle of 18 degrees of the second quadrant, and from that latitude to 46 degrees 4 minutes, in the angle of 12 degrees of the same quadrant; the soundings, the shore, the wooded character of the country, and the little islands, being the same as on the preceding days. On the evening of this day I discovered a large bay, to which I gave the name Assumption Bay, and a plan of which will be found in this journal. Its latitude and longitude are determined according to the most exact means afforded by theory and practice. The latitudes of the two most prominent capes of this bay are calculated from the observations of this day.
