An officer from Japan, visiting America, one day, while looking about a big city, saw a man stop a milk-wagon.

"Is he going to arrest a man?" he asked.
"No," was the answer; "he must see that the milk sold by this man is pure, with no water or chalk mixed with it."
"Would the chalk or water poison the milk?"
"No; but people want pure milk if they pay for it."
Passing a whisky saloon, a man staggered out, struck his head against a lamp-post, and fell to the sidewalk.
"What is the matter with that man?"
"He is full of bad whisky."
"Is it poison?"

"Yes; a deadly poison," was the answer.
"Do you watch the selling of whisky as you do the milk?" asked the Japanese.
"No."
At the markets they found a man looking at the meat to see if it was healthy.
"I can't understand your country," said the Japanese. "You watch the meat and the milk, and let the men sell whisky as much as they please."
