[TYRRELL] THE GOLD OF THE KLONDIKE 55 
confined entirely to the surface gravels and there was none in the 
deeper layers close to the underlying rocks. It had evidently been 
fed into the stream in very recent times and had nothing to do with 
an earlier supply which might have formed a bed-rock pay-streak; and 
it had not worked its way from the surface down to bed-rock. 
Character of the Gold.—The general character and value of the gold 
found in the Klondike has been given in Mr. McConnell’s “ Report on 
the Gold Values in the Klondike High Level Gravels” and need not be 
repeated here. It all contains a considerable percentage of silver, but 
the quality varies to such an extent in different places that while the 
value of the gold on parts of Dominion creek is as high as $17.75 an 
ounce some of that from Last Chance creek is not worth more than $12.- 
50 anounce. The average value of the gold exported from the Klondike 
in 1905 was $16.02 an ounce after it had been melted. 
That in the bottoms of the valleys is generally well rounded and 
water-worn, or perhaps it would be more correct to say beaten round 
while it had been carried along by the water. But much.of the gold in 
the White Channel gravels is more or less angular, and some of it is quite 
clearly crystaline. Many of the crystals are feathery and very delicate, 
and it is possible that some of these may have been deposited on the 
sides of other fragments, or around nuclei through the agency of water 
carrying gold in solution, which percolated downwards through the 
overlying gravel. But other crystals were undoubtedly formed in 
quartz veins and have been mechanically removed to the positions which 
they now occupy in the gravel. Those represented on Plate II are clear 
examples of this class. Figures 1 and 2 are two views of a twinned 
octahedron. Figures 3 and 4 show a cube with hollow faces and with 
the angles modified by the faces of the rhombic dodekahedron. Other 
crystals found by the writer have already been recorded by Professor 
Miers. They occur in a vein of quartz at the head of Victoria Gulch, 
and similar crystals have also been washed out of the gravel on some 
of the mining claims on the Gulch itself. They are octohedra twinned 
parallel to the octohedral face, and are usually in the shape of flattened 
triangular plates. | Those show on Plate I were obtained from Mr. 
Philip Holloway’s claim Number 7, on 7 Pup, Victoria Gulch where 
Mr. Holloway very kindly allowed me to sort over his gold and take 
away these crystals.
