Ask Adventure letter, and so I advise buying a few books and a study of them. Take the books with you on trips into the country (or on your prospecting trips) for reference, and thus have a chance to identify the rocks from descriptions. The method of prospecting is fairly simple and is followed in a general way for all mineral. Hunt first for an area where two different kinds of rock join—say, a granite and a slate, that is an eruptive and a sedimentary rock. Then hunt for a vein of quartz.along that juncture, and when finding such a vein, hunt along its course for mineral, like gold and silver, copper, lead, etc. Fragments broken from such a vein and scattered down-hill below it, sometimes for miles, is called “float.” If you find quartz float containing mineral, follow that kind up-hill till you arrive at the vein. Streams are al- ways good places to hunt for float, because they carry down fragments of quartz from any vein above which crosses the stream, or perhaps crops in the slope on either side. Placer gold is traced in much the same way. If you pan colors, keep panning up-stream watching for more in each pan. The supply should increase toward the source of supply; and in time you may arrive at a point where all colors cease. Your de- posit is then at bed-rock under where the last colors occurred, or up the bank*on either side. Re- member, however, that float gold may be carried for many miles down a stream, or may be in small amounts below some vein bearing gold, and there may be no regular placer deposit; all the float- colors coming from the vein. Watch the beaches of streams, lakes, or sea shore, for quartz float. Also rock- and snow-slides, bare cliffs, etc., for veins. One good book is Horace West’s “The Miner’s 201 Guide,”’ published at 340 Wilcox Bldg., Los Angeles, Calif. Also you need Wilson’s Mining Law of the States, at same address. For California, write to Bureau of Mines, Ferry Bldg., San Francisco. Alaska has been described by me in several letters published by Adventure from time to time. You can also get information by sending to The Director of the U. S. Geological Survey, Washing- ton, D. C., for free Bulletin No. 722, on Alaska Mines & Mining. Prospecting up here requires a boat for traveling—in the states, you mostly use pack animals. Fare up here from Seattle is $34.00 to Ketchikan, our center of fisheries and mining. You might send to the Ketchikan Chronicle, for copy of their recently~issued ‘‘Fisheries Edition,” which describes not only the fishing but also mining, and every other industry. WENTY new sections will be found in the list of experts which follows, in abbreviated form, on the next two pages, and we are arranging to add still more until we shall be prepared to answer questions on all outdoor activities the world around. A list of sections needing experts will be found at the end of the geographical division on page 103. If you think you can qualify as an Ask Adventure expert, we shall be glad to discuss the matter with you. We shall be glad also to receive any suggestions about the department and its work.
