Question

This quote is from an article by the reformer Jacob Riis that appeared in a New York City newspaper in 1891:
"I took my camera and went up in the watershed photographing my evidence wherever I found it. Populous towns sewered directly into our drinking water. I went to the doctors and asked how many days a vigorous cholera bacillus may live and multiply in running water. About seven, said they. My case was made."
