were mistaken for "tin crystals," were sent to various assayers, from 
whom widely divergent reports were obtained. 
Early in the summer of 1903 Charles Ranclt, Leslie Crim, and W. J. 
O'Brien discovered the interesting minerals above referred to in float 
bowlders in Tin Creek, a tributary of Lost River, and made a thorough 
search for tin ore in that vicinity. They made a large collection of 
minerals, which was referred to the writer when he arrived in Teller in 
July, 1903. Metallic tin was readily obtained from one small speci- 
men by aid of a blowpipe, while the larger part of the collection a was 
shown to contain minerals of no value. The collection was of sufficient 
interest to tempt the writer to examine the locality in detail. Mr. 
Hess and the writer proceeded to Lost River and were there able to 
trace the tin ore which had been seen in Teller to the granitic dike on 
Cassiterite Creek, and also to obtain specimens of stannite ore from 
Tin Creek. 
Since this examination the dike described has been called "Cas- 
siterite ledge" in location notices, and it has been definitely traced 
through a group of four claims. A crosscut trench has been made 
near the Cassiterite Creek end of the ledge, which, it is reported, 
shows that the ledge has a width of 100 feet and that cassiterite is 
disseminated throughout the rock. It is also reported that other dis- 
coveries of tin-bearing ledges in this neighborhood have been made 
since July, 1903. The claims located on Cassiterite ledge have been 
purchased by an experienced mine operator and will be developed 
next summer. 
CAPE MOUNTAIN. 
Cape Prince of Wales, the most western point of Seward Peninsula, 
is marked by a high peak known as Cape Mountain. At the south- 
east base of this mountain a settlement called Tin City has grown up 
within the last year. The Eskimo village of Kingegan, the Congrega- 
tional Mission, and Wales post-office are located on the north side, 
facing Bering Strait. From the summit of the mountain East Cape 
and other points on the Asiatic coast, only 60 miles distant, are plainly 
visible on clear days. On its west and south sides this mountain 
slopes down to bluffs that drop perpendicularly into the sea. On its 
southeast side, near Tin City, the coast recedes northward, making a 
bight, which affords some protection from west winds, but for the pre- 
vailing south winds of summer it is practically an open roadstead with 
landing facilities, little, if any, better than those at Nome or York. 
The nearest good anchorage is about 40 miles distant, on Port Clar- 
ence, from which there are several practicable railroad routes. A 
view of this mountain as seen from York, about 12 miles distant, is 
shown in PI. IV. 
a A chemical analysis of one of these samples made by Mr. E. C. Sullivan, of the United States Geo- 
logical Survey, shows no trace of tin. This sample consists mainly of tourmaline.
