Céloron and his detachment, with M. de Contrecoeur as captain, proceeded up the St. Lawrence and into the lakes. After coasting the southern shore of Lake Erie, he arrived at the Chautauqua portage--now known as Barcelona or Portland--on the sixteenth of July; and with the dawn of the following day began the ascent of Chautauqua Creek, called by the French Rivière aux Pommes. Much patience and labor was expended on this unnavigable stream, and it was not until the twenty-second of the following month that the band entered Chautauqua Lake, having spent six days of this time in toiling over the six-mile portage which connects Chautauqua Creek with the lake. Céloron now voyaged down the lake and on the morning of the twenty-fourth of July entered Conewango Creek. The water was low and, borrowing the words of Céloron: "On the 29th at noon I entered 'la Belle Rivière' I buried a plate of lead at the foot of a red oak on the south bank of the river Oyo and of the Chauougon, not far from the village of Kanaouagon, in latitude 42° 5['] 23['']."[3] Of this same occasion Father Bonnécamps wrote: "Finally, overcome with weariness, and almost despairing of seeing the Beautiful River, we entered it on the 29th at noon. Monsieur de Céloron buried a plate of lead on the south bank of the Ohio; and, farther down, he attached the royal coat of arms to a tree. After these operations, we encamped opposite a little Iroquois village, of 12 or 13 cabins; it is called Kananouangon.[4] It is an ancient custom of the French people to assert claim to lands in their possession by burying leaden plates at the mouths of all streams that drain that territory. When Céloron started upon his memorable journey he carried with him six leaden plates. These plates were about eleven inches long, seven and a half inches wide, and one-eighth of an inch thick. Each was engraved with an appropriate inscription, leaving a blank space for date and name of place of deposit at the mouths of the various streams.[5] A _Procès Verbal_, similar in nature to the inscription on the plate, was drawn up and signed by the officers present. To the nearest tree was tacked a plate of sheet-iron stamped with the royal arms. The officers and men of the expedition were drawn up in battle array and the chief in command shouted "Vive le Roi," declaring possession in the name of the King of France. La Salle established this custom on this continent in the latter part of the seventeenth century and now this chevalier of the order of St. Louis penetrates the half-known Central West to make good the precedent established fifty years and more ago.
