I cases. B. obtained the milk sold by him from other parties and pro- 
^ i duced none himself. He was supplied regularly by 3 producers, 
I i E. B. L., C. H., J. B. H., and after April 12 also by J. H. B. C. H. 
ii besides furnishing milk to B. also supplied some in town himself, and 
; ' among his customers only one case occurred. J. B. H. produced 4 
ji 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- 
I 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- 
I 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 
I was therefore a shallow surface well, uncemented, in poorly drained 
soil and in close proximity to two privies. Chemical and bacterio- 
logical examination of the Avater shoAved gross pollution. The last 
[act in the washing of milk cans by B. was to rinse them in cold well 
Avater and invert them to drain and dry. The next morning these 
leans were taken to the producing farms for use. B.’s method of 
I delivery was such that there was no part of his route which might 
iriot have received milk from the E. B. L. farm. B. Avashed 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 tAvo dealers. J. H. B. did not begin to 
furnish milk to B. until after the outbreak was well started and H., 
*H\"ho 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 
Ijthe infection the fact remains that the disease followed the milk of 
^jthis one dairy, B., and of that distributed to the 5 houses personally 
Supplied by E. B. L.
