During the summer it is expected that detailed large scale 
topographic and geologic maps will be made of some of the 
more important mining- centers. 
4. Investigations oil the clays of the state will also be car- 
ried on. A report on highway construction in the state (Bul- 
letin No. X) written by Dr. E. R. Buckley, now state geolo- 
gist of Missouri, has been recenth^ published. 
The International Congress of Geologists will hold 
its ninth session, Aug. 20 to 27th, 1903, inclusive, in the city 
of Vienna. The executive committee has chosen Mr. Max 
v. Gutmann, professor of mines at Vienna, as treasurer in 
place of Mr. F. Karrer, resigned. 
The membership being limited the committee appeals to 
geologists and others, in every land, who are especially inter- 
ested in geological subjects to attend the sessions so far as 
possible. 
The membership fee for this session has been fixed at 
twenty-one francs. This sum should be sent to professor Max 
von Gutmann, Kantgasse, Vienna, Austria. Those desiring 
to take part in the Congress, who shall have sent the registra- 
tion fee will receive a certificate of membership and, later, the 
published transactions of the session. 
In making the program the committee has consulted lead- 
ing scientists in Europe and America and believe that the pa- 
pers and the discussions thereon will modify some current ideas 
upon the great problems of geological science. 
Excursions. — The committee ofifers some fourteen different 
excursions to take place either preceding or immediately fol- 
lowing the session. Each of these will be under the guidance 
of a noted specialist in the field chosen. 
Those who desire to participate in these excursions are 
urged to send their names as soon as possible so that the com- 
mittee can make necessary arrangements for their comfort. 
The Geological Society of Hungary sends out a special in- 
vitation circular to the members of the congress to visit Buda- 
pest and the Danube. The excursion given on the lower Dan- 
ube will be limited to 100 persons. Those desiring to take this 
excursion should make application before June 15 to the gen- 
eral secretary, C. Diener, Vienna, Austria.
