for the purpose of trade, but asa rule are 
immediately after consecration deposited 
in shrines or springs, they are rather diffi- 
cult to obtain, yet the collection numbers 
over 150 specimens of these interesting ob- 
jects, representing nearly every form of 
baho known to the Hopi. 
The figurines produced by the Hopi men 
and given by the mothers to the children 
during the Viman, or Farwell ceremony, and 
known as tihus, are objects found in all 
Hopi collections, but as a matter of fact 
these tihus, which represent certain mytho- 
logical personages called Katcinas, are only 
reproduced for a limited number of char- 
acters. Owing to the unusual zeal shown 
by Mr. Voth toward the collection of this 
class of objects, the collection, with the re- 
cent addition of specimens brought home 
by Mr. Owen, numbers not less than 275, 
comprising over two hundred distinct varie- 
ties, a great many of which were repro- 
duced for Mr. Voth only after earnest 
endeavor on his part. Inasmuch as these 
tihus represent Katcinas and as these Kat- 
cinas play a very important part in the re- 
ligious life of the Hopi the importance of a 
collection of this magnitude, carefully ar- 
ranged and labelled, can not be overesti- 
mated. Even more difficult than these 
tihus to obtain are the masks which are 
worn by the Hopi as they personate deities 
in the Kateina dances. The Hopi regard 
these masks with considerable reverence 
and do not willingly part with them, yet 
the collection numbers one hundred and 
thirty specimens, many of them being made 
of elk or buffalo hide. 
But more important than these collec- 
tions, however valuable and interesting, are 
the altars and sand mosaics, which are faith- 
ful, painstaking reproductions of altars 
which are erected year after,year in the 
underground kivas of the Hopi. There 
may come a time when the actual altars 
themselves may be obtained, but up to the 
SCIENCE.

present, so highly are they revered by the 
Hopi that no sum of money, however great, 
would induce them to part with a single 
slab from a single altar. The altars 
reproduced by Mr. Voth number nine, 
namely—the Antelope, Snake, Flute, Po- 
wamu, Powalawu, Katcina, Soyal, Marau 
and Ooquol. These altars are such as are 
erected by the Hopi during the great nine- 
day ceremonies, and while they do not 
exhaust the subject for even a single Hopi 
village, they are by far the most important 
altars and comprise within their number all 
those which contain images or fetishes. In 
most of the ceremonies represented by these 
altars, during the years when initiations are 
performed, sand mosaics are added to the 
altar, and comprised within the altars which 
have been reproduced are all those which 
contain this additional feature of interest. 
Mr. Voth also reproduced the great Ballu- 
lukon screen which is erected in the kiva 
during one of the ceremonies, and which is 
manipulated by means of concealed wires, 
to the intense delight of priests and the 
great mystification of the novitiates present. 
The work which has been accomplished 
by the McCormick expeditions up to the 
present time has, I believe, been thorough 
and in every sense worthy the generosity 
of the patron. It must be admitted, how- 
ever, that much yet remains to be done of 
equal value and importance among the 
Hopi of to-day and among the ruins of the 
past.
