 studies, an explanation of it will perhaps be suggested by com- 

 paring the present climatic conditions of the two regions."

No. 259. Report on Progress of Investigations of Mineral 

 Resources of Alaska in 1904 ; by Alfred H. Brooks and others. 

 196 pp., 3 plates, 10 figures. — This bulletin gives an account, by 

 the different geologists at work, of the information gathered dur- 

 ing the last season in regard to the various mineral deposits of 

 Alaska. Nine parties were in the field, five of them engaged in 

 geologic work, two in topographic surveys, one was a combined 

 geologic and topographic party and one studied the methods and 

 costs of placer mining. The larger part of the bulletin is devoted 

 to the gold placers, but an account is also given of the Treadwell 

 ore deposits on Douglas Island, as, too, of the recent develop- 

 ment of tin deposits in Alaska. Further, the coal and petroleum 

 resources of Alaska are discussed in detail (see also Bulletin No. 

 250).

No. 264. Record of Deep Well Drilling for 1904 ; by M. L. 

 Fuller, E. F. Lines and A. C. Veatch. 106 pp. — The work of 

 the Survey, in regard to the accummulation of geological and 

 physical data of deep wells, although only recently inaugurated, 

 is now so well organized that a very large amount of useful 

 material is promptly brought together and given to the public. 

 The paper now issued is the first of the series planned and 

 presents the material received during the first six months of the 

 work. A tabular summary is given for 358 wells and detailed 

 records are added of a number of selected cases yielding infor- 

 mation of importance.
