timore there are a dozen or more men working on signalling and balloon 
problems under the general direction of Major Wood. At Pittsburgh, where 
the shops of the Carnegie Institute of Technology have been turned over to 
the work of the Physics and Engineering Divisions of the National Research 
Council, there are a dozen or more physicists, engineers, and mechanics work- 
ing upon the design and construction of apparatus. At Columbia University 
there are some five or six men working on a special and important problem. 
Since the final testing is done under the authority of the Division of Military 
Aeronautics there are always a number of men who are at the aviation fields 
assisting in the making of final acceptance tests. 
The work of the Science and Research Department outlined above covers 
the problems which come under the authority of the Bureau of Aircraft Pro- 
duction, the Division of Military Aeronautics, and the Signal Corps; but, 
through the activity of the Physics Committee of the National Research Coun- 
cil, investigations have been initiated which come within the authority of 
other Bureaus of the Army and the Navy. 
Thus, the whole sound ranging work, the investigation of the location of 
aircraft by sound, and certain other allied investigations were transferred to 
the authority of the Engineers Corps after they had been gotten well under 
way by representatives of the Research Council. These representatives still 
act as an integral part of the groups, and the results of the investigations are 
reported by the Engineers Corps to the central office of the Research Council; 
so that the Division of Physical Sciences of the Research Council is still acting 
in an advisory and stimulating capacity in all these fields, and the problems 
themselves are discussed in the executive committee meetings of the Division 
of Physical Sciences. 
The Anti-Submarine group, of New London, furnishes another illustration 
of the way in which these developments take place. The ten scientific men 
constituting this group were chosen in June, 1917, and their activities financed 
for a number of months by the Research Council, but the funds for their re- 
search work are now supplied entirely by the Navy. The reports of the results 
of this work are made, however, to the National Research Council, and the 
Executive Committee of the Division of Physical Sciences is represented in the 
New London meetings which are held each week. 
Precisely similar relations are held in regard to certain problems coming 
under the authority of the Bureau of Ordnance of the Navy, the Ordnance 
Department of the Army, and the Coast Artillery Board. 
The Executive Committee of the Division of Physical Sciences has met but 
twice during the past month. It has added a number of new problems to the 
list of approximately eighty which are receiving the attention of this Division. 
Mr. E. F. Nichols, who is Chairman of the Committee on Submarine 
Mines of the Physics Division, has been employed by the Bureau of Ordnance 
of the Navy for th e fuller development and production of devices relating to 
Naval Ordnance.
