NO. II SMITHSONIAN EXPEDITIONS, IQIO-IQII 27 
The Albatross left San Diego, California, February 28, 1911, visited Guada- 
loupe Island, and then proceeded down the coast of Lower California to the 
Gulf of California, which was traversed as far north as Angel de la Guarda 
Island. Dredgings were made off the outer coast of Lower California, both 
going and returning, and shore and shallow water collecting was carried on 
in the Gulf. Owing to the short duration of the cruise, somewhat less than 
two months, it was impossible to make more than a brief stop at any place, but 
nevertheless, the results of the trip were exceedingly satisfactory. Of marine 
invertebrates, especially moilusks, a large and fine series was obtained, and of 
plants, about 2,000 herbarium specimens and 1,000 living specimens, mostly cacti, 
were secured.’

FIELD WORK OF THE BUREAU OF AMERICAN ETHNOLOGY 
It would be impossible in this brief review of Smithsonian explora- 
tions to summarize the extensive field operations of the Bureau of 
American Ethnology. This is, indeed, made unnecessary from the 
fact that they are already mentioned in some detail by the Ethnologist- 
in-charge, in the reports of the Secretary of the Institution for 1910 
and IgIt. 
Researches were carried on during the year I9g10, among the 
Pueblos, Winnebago, Blackfeet, Northern Cheyenne, Northern 
Arapaho, Coos, Piegan, and Omaha Indians. Investigations were
