a part of the Sandy-bay of Graybeast River, the trap formation, which is the copper-bearing rock, is first seen.  This rock, which forms the great peninsula of Kewywenon, rises into cliffs on this bay, which at the elevation called Mammels by the French, deserve the name of mountains.  Portions of this rock, viewed in extenso, are overlaid by amygdaloid and rubblestone—­the latter of which forms a remarkable edging to the formation, in some places, on the north-west shore, that makes a canal, as at the Little Marrias.

KEWEENA PENINSULA.—­We were six days in coasting around this peninsula, which is highly metalliferous.  At some points we employed the blast, to ascertain the true character and contents of the soil.  At others we went inland, and devoted the time in exploring its range and extent.  We examined the outstanding isolated vein of carbonate of copper, called Roche Vert by the French.  In seeking for its connection on the main shore, I discovered the black oxide in the same vein.  In the range of the greenstone about two leagues south of this point, a vein of native copper, with ores and veinstones, was observed, and specimens taken.

The N.W. coast of the peninsula is greatly serrated and broken, abounding in little bays and inlets, and giving proofs of the terrible action of the storms on this rugged shore.

Notes of these examinations and of a trip inland were made, which cannot here be referred to more particularly.

UNFLEDGED DUCKS.—­The men had rare and very exciting sport, in coasting around the peninsula, in catching the young of the onzig—­which is the sawbill.  In the early part of the month of July, the wings of the young are not sufficiently developed to enable them to fly.  They will run on the water, flapping their unfledged wings, with great speed, but the gay Frenchmen, shouting at the top of their lungs, would propel their canoes so as to overtake them whenever the little fugitives could not find some nook in the rock to hide in.  They chased down one day thirteen in this way, which were found a most tender and delicate dish.  The excitement in these chases was extreme.  At the Grand Marrias (now near Fort Wilkins) we obtained from the shore of the inner bay, agates, stilbite, and smoky quartz, &c.

SINGULAR VIVACITY.—­In going from this bay through a rock-bound strait, the rain fell literally in sheets.  There was no escape, and our only philosophy was to sit still and bear it.  The shower was so great that it obscured objects at a short distance.  All at once the men struck up a cheerful boat song, which they continued, paddling with renewed energy, till the shower abated.  I believe no other people under the sun would have thought of such a resource.
