Mcrtie, ir, whose report on hs work has just been published in the Surveys Bulletin 692-D. Mir. Mcr- tic gives a geologic sketch map of the region, describes its geography and geology, and presents an account of ilS mineral resources, which includes de- Scriptions of the placers on many creeks. Though gold is the only min eral thus far recovered in commercial quantities the paccrS have yielded small quantities of other valuable min erals, which include platinum and ores of tin and tungsten.
 Deposits of Chromitc in Alaska.
 Deposits of chromitc have been been known in Alaska for several ycarS, but they become of economic interest only in 1917, when the high price of the orc made it possible to mine it commercially at one property. The chromitc deposits Of present in tercSt in Alaska are at the southwest end of Kenai Peninsula. A description ot the dcDoSit now mined and map showing it's location are given in d short paper by J. B. Mertie jr., pub HShcd as part of Bulletin 692-D.
 Geologic Problems in the Matanuska
 Coal Field.
 The result of studies of the strata and of the structure in the Matanuska coal field, Alaska, made in 1917 by G. C. Martin, are reported in paper just published in Bulletin 692-D. The paper includes sections showing the char acter, relations, and thickness of the beds of rock and coal at many Iocali- ties. as well as a graphic section show ing tentative correlation of certain coal beds between places specified.
 Mining in the Fairbanks District.
 The Fairbanks district, in the Yukon basin, has produced over S70000,0O0 in gold and has been a source of con siderable silver lead, tungsten, and antimony. The conditions in the dis trict in 1917 are reported in a paper by Theodore Chapn that forms par. of Bulletin 692-F. Mr. Chapin give an account of the operations at tho gold and the silver-lead lodeS and at the tungsten deposits.
 \ MOlyhdenite Lode on Healy River
 A Molyhdenite bearing quartz vein on Healy River, Alaska, which has been traced by shallow openings for the length of three claims, is the sub icct Of a brief note by Theodore Chap in in Bulletin 692-F
 Mining in the Hot Springs District.
 The Hot Springs district, in Alaska, has produced more than $6,000,000 in placer gold. well as some silver and tin. Mr. Theodore Chapin, in papcr in Bulletin 692-F, describes the occur renee of tin ore in the district, and gives an account oc the mining opera tionS there in 1917,
 Tin in the Ruby District, Alaska
 Ores of tin are scarce in the United States, and their occurrence in AlaSko is therefore of interest. Stream tin has been found in gold placers in the Ruby district at several places, but nor in quantities large enough to pay for mining it except as an accessory to tn" gold. A short note on the tin in this district by Theodore Chapin is given in Bulletin 692-F
 Gold and Platinum placcrS in the
 TolStOi District.
 The ToStoi district includes an area about l2 miles wide by 20 miles long, which lies on the Hanks of Mount Hurst. Most Of the district is in the basin of Tolstoi River, on the branchcS of which DlaccrS that yield gold and platinum have been worked for sever al years. The topography, geology, eli mate vegetation, and animal life of the district, the producing place,s. and the economic factors that affect mining arc described by G. l.. Ha,r'- iagton in Bulletin 692-F.
 Tin Mining in Seward Peninsula
 Stream tin, form of cassiterite, the most valuable ore of tin, has been found in many streams in Alaska, and lodcs of c2SSiterite have been pro spected and mined at several places in the Territory. An account of the tin deposits given by G. l.. Harrington in Bulletin 692-G, which contains de-
