and other work begun in preceding years, utilizing such por- 
tions of my time as were not absorbed in work, pertaining to the 
U. S. Geological Survey. A paper on the antiquities of Chiriqui 
and one on textile art in its relation to form and ornament, 
prepared for the Sixth Annual report, were completed and proofs 
were read* During the year work was begun upon a review of the 
ceramic art of Mexico* A special paper, with twenty illustra- 
tions, on a remarkable group of spurious antiquities belonging 
to that country, was prepared and turned over to the Smithsonian 
Institution for publication* In addition, a preliminary study

paper with numerous illustrations was written. As in former 
years, I superintended the preparation of drawings and engravings 
for the Bureau publications* The number of illustrations pre- 
pared during the year amounted to 660.
