NATIONAL RESEARCH COUNCIL 
At a meeting of the Division held on June 5 and 6, the following temporary 
committees were appointed. 
Funds: Ralph Arnold, Chairman. 
Rocky Mountain and Geology Conference: Eliot Blackwelder, Chairman. 
Committee on Certain Seismological Investigations: H. F. Reid, Chairman. 
Conference Committee on Survey of the Sea: J. Russell Smith, Chairman. 
List of Scientific Travelers: Isaiah Bowman, Chairman. 
Development of Geographical Sciences: W. M. Davis, Chairman. 
The Division passed the following resolution on the coordination in field 
methods of map-making agencies of the Government which it has referred to 
the Division of Government Relations. 
Whereas the several mapping agencies of the United States are making actual surveys by- 
different methods on different scales and with wide variation in accuracy of field work. 
Whereas the results of actual field surveys are not mutually available to the different 
map-making organizations because of these differences and a lack of means by which the 
relative accuracy of the different parts of the field work can be readily ascertained. 
Whereas such lack of coordination in field methods and degree of accuracy leads to sur- 
veys and avoidable expense, the Division of Geology and Geography. 
Recommends to the Division of Government Relations that a Committee be appointed 
representing the several map-making agencies of the Government to arrange a plan of oper- 
ation by which organizations conducting surveys secure and record their field data in such 
manner that they may be fully usable by other map-making agencies of the Government 
interested in the same areas. 
To this end their Committee should define 
1. The degree of accuracy or "tolerance" in field work. 
2. Standard methods of expression which shall discriminate the relative accuracy of deter- 
mination of the several horizontal and vertical elements. 
3. One or more standard scales and projections for field mapping. 
It is further suggested that this work may be done by a new committee or 
entrusted to the recently organized Committee of Aeronautic Mapping if its 
scope may be broadened. 
The Division requests the appointment of a Conference Committee by the 
Division of Biology on Survey of the Sea, also the appointment of a member of 
the Division of Physical Sciences on its Committee on certain proposals for 
seismological investigations offered by Dr. Wood. 
The Division requests the National Research Council to prepare for publi- 
cation a record of the work of scientific men in connection with the war. 
In response to the inquiry from the Secretary of the National Research Coun- 
cil, the Division 
Voted that the Division of Geology and Geography approve the formation 
of international associations of geologists and of geographers under the aus- 
pices of the International Research Council and recommend that two dele- 
gates — a geologist and a geographer — be sent to the conference to be held 
in Brussels, in July 1919.
