where they are found, together with references to the works 
and periodicals in which they are mentioned, which Mrs. V. L. 
Thomas, in addition to her other duties, has been engaged 
upon for nearly three years, is now completed, and is being 
used in the preparation of maps. It will be issued as a bul- 
letin. 
Mr. Grrarp Fowxs, in addition to assisting in the prepara- 
tion of the final report on the field work of the mound explo- 
ration division, has made a study of the stone articles of the 
collection made by it. 
Mr. H. L. Reynoups has made a study of the copper articles
