GAY GULCH AND SKOOKUM METEORITES.

be determined with accuracy, but it is probably referable to 
lamprite. 
The general distribution of these pittings along directions 
parallel with the faces of the octahedron is strongly suggestive 
of an octahedral structure for this iron. If this iron should 
eventually prove to be an octahedrite it is remarkable for the 
high percentage of nickel which it contains as indicated by a partial 
analysis conducted in the laboratory of the Mines Branch of the 
Department of Mines by Mr. H. A. Leverin, who found for it 
the following figures: iron 83-85, nickel 15-03. The specific 
gravity as determined by the author was found to be 7 • 566. 
SKOOKUM. 
The second specimen was found January 21, 1905, by Mr. 
W. Kast, on claim No. 7, Skookum gulch — latitude 63° 56' N.> 
longitude 139° 20' W. By reference to the diagram it will be ob- 
served that this gulch enters Bonanza creek about half a mile 
below Eldorado Forks, and approximately 9| miles in a south- 
easterly direction from the town of Dawson. At the time of 
the discovery, claim No. 7 was being worked under the terms 
of a lease and a dispute arose over the ownership of the meteor- 
ite. An agreement was after a time effected, by which Mr. 
Kast retained possession and he afterward exhibited the speci- 
men at the Alaska-Y ukon-Pacific exposition at Seattle, Wash., 
U.S.A., in 1909, where it was secured for the Museum of the 
Geological Survey by the late Mr. R. L. Broadbent. 
This iron was encountered in white channel gravels 65 feet 
below the surface of the ground and between 2 and 3 feet above 
bed-rock. In form it was, roughly speaking, a block varying 
in thickness from 3 to 8 centimetres and exhibiting an irregular 
pentagonal outline; it measured 29 centimetres in length by 23 
in width and weighed 15 • 88 kilogrammes. It was characterized 
by a number of broad and shallow depressions, one of which 
had a breadth of 21 centimetres with a maximum depth of 
2 centimetres. These depressions were further marked by 
abundant small pittings. The exterior character of this iron is well 
illustrated in Plates IV, V, and VI. Portions of the surface had
