OF THE BOUNDARY COMMISSION. 551 
Paso, and thence through Chihuahua and the Mexican 
States to the south, Dr. Webb was enabled to make a 
collection of fossils and minerals, including some choice 
specimens of gold and silver ores, which were brought 
home in safety A collection of fossils and minerals in 
the valley of the Rio Grande was also made by Mr. 
Arthur Schott. ° 
In ethnology the collection was made almost ex- 
clusively by myself. This consists of vocabularies, 
each embracing two hundred words, in upwards of 
twenty Indian languages. Many of these had never 
been taken down before, and few as fully as by me. 
Further to illustrate the aboriginal tribes, I have 
obtained accurate and characteristic portraits of many 
individuals seen, both male and female, with sketches 
exhibiting their manners and customs, their arts, hus- 
bandry, ete. 
I had prepared an extended disquisition on the 
semi-civilized tribes occupying the vast basin between 
the Rocky Mountains, or rather the Rio Grande, and 
the Colorado of California; but the subject was found 
to be so extensive and so deeply interesting, that I 
determined to reserve it for a special report, which | 
intend to prepare on the ethnology of the Indian tribes 
of the extensive region explored by the Boundary 
Commission, in which also my Indian vocabularies 
will be embraced. 
By the preceding statement it will be seen that no 
exertions were spared, and no suitable opportunities 
omitted, to do all in my power to advance the cause of 
science. It now remains for the government to take 
such measures as it may deem proper to lay the results
