Show SULPHUR DEPOSITS OF ALASKA EXTENSIVE The known sulphur deposits of Alaska are of volcanic origin anil lie in the bell of active volcanoes that extends through the Aleutian islands and Alaska peninsula. penin-sula. The deposits on I'nalaska and Akun islands and near Stepovak hay, on Alaska peninsula, were examined in the summer of 1IU7 by A. G. Maddren of the United States ecological survey, d opart men t of the interior. The examinations showed that though there is some sulphur at eaeh place examined there is little hope that any of it can be profitably mined at present or in the near future, for the deposits de-posits are of small areal extent and are prohably shallow, supplies and labor are not at hand, the open season is short, the difficulties of transporting the material mate-rial from the mines to ships would be great, and the haul to the larger markets would lie long. A brief summary of the more important results of the investigation investiga-tion of these deposits lias been published pub-lished and will be sent on application to the director of the geological survey, Washington, D.
