Messrs. G. F. Becker, S. F. Emmons, and C. R. \'an Hise 
have been appointed delegates to the International Congress 
of Geologists at Vienna. 
Dr. Arthur C. Spencer is to spend the pres«it field season 
in Alaska, investigating the geology of Douglas island and 
making a special study of the ore deposits of the Treadwell 
mine. 
American Institute of Mining Engineers. The meet- 
ing of the Institute arranged for July in British Columbia, with 
an excursion to Alaska, will not be held. 
The library of the Institute, located at the secretary's office. 
No. 99 John "street, New York City, comprises about 10,000 
volumes, having been recently enriched by the deposit of the 
books of R. W. Raymond and of the libraries of the late Clar- 
ence King and R. P. Rothwell. These vohimes, combined with 
the large list of technical papers and government reports owned 
by the Institute, make a very valuable collection of literature 
on geology, mining, metallurgy and the allied arts. It is felt 
that the library, already possessing such a fine nucleus, should 
be made a complete reference library for the profession, and 
with that end in view it is proposed to raise a fund of $25,000 
for the acquisition of additional books and for proper cata- 
loguing. If a sufficient amount is raised, it will be possible to 
publish and forward to members of the Institute a complete 
classified index of the library and to engage a librarian compe- 
tent to hunt up and abstract reports for members. This will 
be of special service to* engineers remote from libraries. The 
important libraries of the late Clarence King and R. P. Roth- 
well, above mentioned, have been secured through the generos- 
ity of Mr. John Hays Hammond, and at his request will be 
known as the "Raymond memorial library." 
Wisconsin Geological and Natural History Survey. 
The geological work of the survey for the coming summer 
will be along the following lines : 
1. Dr. Samuel Weidman, assisted by Mr. W. D. Smith of 
the University of Wisconsin, is to spend the earlier part of the 
season in a study of the district about Baraboo where recent 
developments have shown the existence of deposits of hematite 
in a slate or iron-bearing formation which overlies the Baraboo 
quartzite. 
2. Later in the season Messrs. Weidman and Smith will 
return to the area of crystalline rocks in the north-central part 
of the state (vicinity of Wausau) with the expectation of com- 
pleting the work in this flistrict for a report on the general 
geology and also on the glacial features. 
3. Professor U. S. Grant of Northwestern University will 
continue work in the lead and zinc district of the southwestern 
corner of the state, a preliminary report on which has just been 
published (Bulletin Xo. IX). He will be assisted by Messrs.
