Long cylindrical tubes resembling those here figured from Las Guacas were, as 
is well known, worn by the ancient Mayas and Mexicans as horizontal breast-orna- 
ments. Beside their use as amulets they probably also served other purposes. The 
use of cane tubes by the medicine men for sucking prevails still in certain parts of 
Mexico as amongst the Tarahumares in Chihuahua. About the use of stone tubes 
for this purpose amongst the aborigines of California it may be of interest to give the 
following quotation” from E. G. Squier after Vanegas, ‘‘One mode (for curing dis- 
ease) was very remarkable, and the good effect it sometimes produced heightened 
the reputation of the physician. They applied to the suffering part of the patient’s 
body the chacuaco, a tube formed out of a very hard black stone ; and through this 
they sometimes sucked and at other times blew, but both as hard as they were able, 
supposing that the disease was either exhaled or dispersed. Sometimes the tube was 
filled with cimarron or wild tobacco lighted and here they either sucked in or blew 
down the smoke, according to the physician’s directions; and this powerful caustic 
sometimes without any other remedy has been known to entirely remove the 
disorder.” 
Quite a number of stone tubes varying in size and shape were encountered at 
Las Guacas. ‘The largest are 12-20 cm. in length. They are all provided with a
