described, were made during the course of these studies in 
Berlin. He also visited the museum at Copenhagen, Den- 
mark, which contains many old specimens from the Danish 
West Indies and some rare types of prehistoric objects from 
Porto Rico, all of which were either drawn or photographed. 
West Indian objects were found also in the museum collec- 
tions of Leipzig, Dresden, and Vienna. Some time was 
given to an examination of the dolmens and megaliths in 
the neighborhood of Berlin and elsewhere in northern 
Germany, and of the numerous mounds and _ prehistoric 
workshops on the island of Rugen in the Baltic Sea. 
Doctor Fewkes spent his vacation on the shore of the 
Mediterranean, which he crossed, visiting the most striking 
ruins in Egypt, penetrating as far south as Assouan, and 
making special studies of the remaining evidences of neo- 
lithie man at Abydos and El Kab on the banks of the Nile. 
He had always in mind a study of prehistoric irrigation in 
this region, with a view to comparing the works with similar 
remains in Arizona. In the museums at Cairo and Assouan 
Doctor Fewkes examined considerable material dating back 
to late neolithic times and found a remarkable similarity 
not only in architectural features but also in stone imple- 
ments, basketry, bone implements, and other artifacts from 
the valley of the Nile and those from our Southwest. One of 
the important features of the visit to Egypt was a study of 
methods of excavation and repair of ruins adopted by Egyp- 
tologists. On his return from Egypt Doctor Fewkes passed 
through Greece and southern Italy and was able to acquaint 
himself with the method of excavation and repair of ancient 
ruins in these countries, especially those on the Acropolis 
and at Pompeii. 
Doctor Fewkes arrived in Washington in April and imme- 
diately resumed work on his report on the aborigines of the 
West Indies, which was continued during April and the 
greater part of May. In the latter month he again took the 
field and spent the whole of June in archeological research in 
the Mimbres Valley, New Mexico. In this work he was able 
to enlarge our knowledge of the distribution of pottery 
symbols and to add important collections to the National
