The Institute for the Prehistory of Switzerland 
(Institut fur Ur & Frühgeschichte der Schweiz) of the 
University of Basle and the Swiss Prehistoric Society 
have for many years made a modest use of photographs 
in their studies of ancient cultures and in their search 
for remains of such, which are not detectable or visible 
on the ground. This has not been too successful due 
mainly to the very intense and changing cultivation over 
many centuries. Discoveries of hitherto unknown sites, 
mainly shadow-sites, have been accidental. Efforts now 
employ a systematic method using the cooperation of the 
Federal Topographic Survey's flying and photographic 
services along with Air Force equipment. It is now 
possible to obtain special photographs which give 
accurately the specific requirements of archaeological 
photo interpretation. It is the Society's special 
aim to conduct systematic studies for locating subaquatic 
remains of the numerous pile-dweller stations in our 
subalpine lakes. Though haphazard photographs, taken by 
the "Swissair" over the lake of Geneva seem to confirm 
the value of such endeavors, sofar results have not been 
very encouraging. Aerial photographs were used extensively 
and with good success in a study of the "Roman Limitation 
in western Switzerland" by Dr. G. Grosjean of the geographical 
department of the University of Berne. Crop-sites and soil- 
marks have contributed to the success. A publication will 
appear during the year on this. Accidental crop-site 
discoveries have greatly facilitated the excavation of 
several "insulae" of the otherwise well known roman city 
of Augusta Rauracorum, the present day village of Augst 
near Basle.
