It proved to be so difficult to obtain specimens of feces from the 
brickyards that no microscopic examinations were made. Xo clew 
was obtained to anv disease amono- the workers which could be inter- 
preted as probable uncinariasis. 
Besides Dr. Carrington. I am indebted to Dr. Staton also for 
cooperation in my work at Richmond.

Yirgilina Coj)j)er 2Rne district, southern Yircjinia and nerrthern 
JYorth Carolina. — Proceeding to the Yirgilina copper mine district I 
found it very difficult at first to obtain specimens for examination. 
At one mine 1 white male and 3 negro males were examined; all were 
negative except 1 negro 22 years old, who showed infection with 
Asca/ris lurrdjricoides. At this mine defecation under ground is pro- 
hibited; it occurs in the surrounding woods, at any place within a 
radius of about 50 meters from the shaft. 
At a second mine three specimens of feces were taken at random 
from the woods: eggs of Uncinaria arnericana were found in one 
specimen, and ova of Ascaris lundrricoides in a second. The patients 
could not be traced. Specimens were then obtained from d white and 
18 negro miners, the feces being taken without reference to the | 
physical condition of the men. Of these 22 men, 1 negro 25 years | 
old showed a light infection with Uncinarki arnericana, and incpiiry | 
developed the fact that he "had not been well for some time." His 
chief complaint had been ‘Aliarrhea." In two other cases, a wffiite 
man dl years old and a negro 3d years old. eggs of the eelworm {Asca- 
ris hirnbricoides) were found. At this mine defecation under ground 
is prohibited, and a box privy is located within about 50 meters of 
the shaft. The men prefer, however, to defecate in the surrounding 
woods. 
I am indebted to Drs. P. D. Drewry and P. P. Causey, and to Mr. 
L. X. White, manager of the Person Consolidated Copper and Gold 
iNIines Company at Durgy, X. C., for their kind cooperation in con- 
nection with mv work in Yirgilina and vicinity. 
CurnnocTi Coal Fines. Chatham County. — The miners at this place 
were so suspicious regarding my work that it was almost impossible 
to obtain specimens for examination. In fact only two specimens • 
could be obtained from about dO men. One of these, a white miner, 
52 years of age, and in rather anemic condition, showed infection with 
Uncinaria arnericana. The other, a white engineer, 3d years old, 
gave negative results. ! 
Sanford,, Jloo're County. — Specimens from d whites (2 males, and 2 
females), obtained by 2 of the local physicians, were examined with > 
negative results.
