WHEREAS the diversity of tongues is a continuing 
hindrance to interchange of knowledge and litera- 
tures, seriously enhancing the cost and labor of 
studious pursuits, which might in large measure be 
avoided by the adoption by the civilized nations of 
an Alternate Language of Learning, Law and Com- 
merce, and as such required to be taught in higher 
schools (in combination with the mother tongue) and 
used in interlingual correspondence and printed 
records ; and 
WHEREAS it is believed this need is felt and ac- 
knowledged by societies and corporations of several 
nations and awaits the initiative of some one of them 
to propose concerted action thereon ; now, therefore, 
be it 
Resolved, That whenever the President or Permanent 
Secretary of the Association shall have received from 
similar bodies, or from universities of Europe, ex- 
pressions sufficient in number to represent a majority 
of the maritime peoples, signifying a desire to coope- 
rate inan International Conference of Languages, it 
shall be his duty to lay the same before the Council 
at the next regular, or, if neeed be, at a specially- 
called, meeting, with the view to the appointment of 
one or more delegates to represent American Pedagogy 
and Science thereat, at some convenient time and place 
in central Europe. 
In like manner the Permanent Secretary is hereby 
authorized to acknowledge, on behalf of this Associa- 
tion, receipt of such invitation for a like purpose 
emanating from any government, or department 
thereof, Institution of Learning, Technical Science, 
Chamber of Commerce or Finance, Telegraphic or 
Transportation Bureau, Postal Union or Academy of 
Arts and Letters, and to pledge the further attention 
of this Council to the same. 
GEOLOGY AND GEOGRAPHY AT 1HE AMERI- 
CAN ASSOCIATION FOR THE AD- 
; VANCEMENT OF SCIENCE. 
Proressor I. C. Wurte, Chairman of the 
Section, being in attendance upon the In- 
ternational Geological Congress in Russia, 
the Council filled the vacancy by the elec- 
tion of Professor E. W. Claypole, who read 
Professor White’s address and presided over 
the meetings of the Section. : 
After the presentation of the vice-presi- 
dential address, the following papers were 
read : 
1. ‘The Geological Age and Fauna of 
the Huerfano Basin, in Southern Colorado,’ 
by Professor H. F. Osborn, New York. 
SCIENCE. 
[N. S. Vou. VI. No. 149. 
The author reviewed the work of R. C. 
Hills, and concluded from recent field work 
that the Huerfano Lake deposits are from 
800-1000 thick, consisting of upper beds 
equivalent to Bridger, and lower beds 
equivalent to Wind River and Wasatch. 
Below them is an unconformable series, 
probably Cretaceous. The distribution of 
deposits indicates a different extension of 
the lake from that given by Hills. Brief 
reference was made to the fossils found. 
2. ‘Lake Chicago and the Chicago Out- 
let,’ by Frank Leverett, Denmark, Iowa. 
The paper discussed, in detail and with 
abundant data, the beaches and outlet of 
Lake Chicago, a glacial lake having south- 
ward discharge from the southern end of 
Lake Michigan basin, through the Des 
Plaines and Illinois rivers to the Missis- 
Ssippi. 
3. ‘Some Features of the Recent Geology 
Around Detroit,’ by Frank B. Taylor, Fort 
Wayne, Ind. Detroit is built on moraines 
deposited under 200 feet of water. While 
the ice front was here the western half of 
Hrie basin was filled by a glacial lake. 
This gives a very smooth surface contour. 
Shore lines and beaches are well developed. 
The lower courses of old tributaries of De- 
troit riverare drowned. Streams two miles 
long have deep estuaries, much deeper than 
they could erode under present conditions, 
é. g., Rouge River and Baby Creek. Rouge 
River, four miles above its mouth, has an 
average mid-stream depth of from 20 to 30 
feet, four times deeper than would be ex- 
pected from the stream’s own erosion. The 
same is true of the St. Clair tributaries. 
The succession of events has been as fol- 
lows: The rivers first flowed as now, but 
slightly higher. Then, while the upper lakes 
drained to the Ottawa, abandoning the St. 
Clair and Detroit Rivers, the streams were 
cutting to a base level from 25 to 30 feet lower 
than presentriver surface. Finally, a north- 
east uplift established existing conditions
