cases. B. obtained the milk sold by him from other parties and pro- 
duced none himself. He was supplied regularly by 3 producers, 
E. B. L., C. H., J. B. H., and after April 12 also by J. H. B. C. H. 
besides furnishing milk to B. also supplied some in town himself, and 
among his customers only one case occurred. J. B. H. produced 4 
cans of milk a day; one can went to B. ad 3 cans to dairyman H. H., 
on whose route occurred only 5 cases of typhoid. E. B. L. furnished 
B. from 140 to 150 quarts of milk daily; this constituted over one- 
half of B.’s supply. In fact, all that E. B. L. produced went to B., 
except a few quarts which he distributed to 5 families. It is signifi- 
cant that in these 5 households there were 8 cases of typhoid. 
B.’s dairy was situated in a low, poorly drained part of the city. 
The water used to wash cans was from an uncemented dug well with 
a loose board cover 6 inches above the ground level. The well was 
13J feet deep and the water stood within 1 foot 9 inches of the top. 
There was a shallow, foul privy 25 feet west of the well on slightly 
higher ground, and another 40 feet to the east. The water supply 
was therefore a shallow surface Avell, uncemented, in poorly drained 
soil and in close proximity to two privies. Chemical and bacterio- 
logical examination of the water showed gross pollution. The last 
act in the washing of milk cans b}^ B. was to rinse them in cold well 
water and invert them to drain and dry. The next morning these 
cans were taken to the producing farms for use. B.’s method of 
delivery was such that there was no part of his route which might 
not have received milk from the E. B. L. farm. B. washed all the 
cans coming to him and returned them clean to the producers. 
Farmer C. H. scalded the returned cans before refilling. E. B. L. 
refilled the cans just as they came from B., all of his milk going into 
them, including that which he delivered to his 5 personal customers. 
J. B. H. refilled cans returned from B. without any extra treatment. 
He had, however, in use 8 cans, one of which was returned daily from 
B., and 3 taken to H. H. No precautions were taken to keep separate 
the cans coming from the two dealers. J. H. B. did not begin to 
furnish milk to B. until after the outbreak was well started and H., 
who handled most of his milk, had only one case on his route. 
No case of typhoid was found at the dairy or producing farms, 
but the hypothesis that the well water at dairy B. was infected would 
explain all the features of the epidemic, and whatever the source of 
the infection the fact remains that the disease followed the milk of 
this one dairy, B., and of that distributed to the 5 houses personally 
supplied by E. B. L.
