It has been shown that the value of the annual gold production of Seward Peninsula is now (1906) about $7,500,000 and that the total. including 1906, is nearly $40,000,000. This has practically all been derived from the placers, though a small amount has been obtained from auriferous quartz veins. All of the placer gold carries some silver, the present annual production of which is valued at about $25,000. Of other mineral wealth tin is the only metal of immediate interest. Some placer tin has been exported, and the development of both lode and placer deposits is being actively pushed, but up to the present the tin deposits can not be said to have reached a productive stage. There are a few small areas9 of coal-bearing rocks on the peninsula, but in only one of these has a workable seam been found, and this appears to be of value only for the very local demand.T Besides the above minerals, graphite and bismuth deserve mention, though their commercial value in this field remains to be proved. A general account of the piacers will next be presented, followed by a detailed description of the gold deposits of the Nome, Solomon. Council. Port Clarence, and Goodhope districts. In later sections of the report an account of the Bluff and Kougarok regions will be presented by Mr. Brooks, and of Iron Creek by Mr. Smith. DISTRIBUTION OF GOLD. On the geologic maps (Pis. X and XI, in pocket) is indicated the distribution of the unconsolidated silts, sands, and gravels, under the general group name Quaternary. These deposits have already been discussed at some length in the section devoted to the geologyof the peninsula (pp. 83-99). As these Quaternary beds carry the "See...
