"Can I run this train from Springfield to Boston at the rate of fifty miles an hour ?" says an engineer.Yes.

"Then I will run it reckless of consequences." Can I be a merchant, and the president of a bank, and a director in a life insurance company, and a school commissioner, and help edit a paper, and supervise the politics of our ward, and run for Congress?
"I can!" the man says to himself.

The store drives him; the school drives him; politics drive him.
He takes all the scoldings and frets and exasperations of each position.
Some day at the height of the business season he does not come to the store; from the most important meetings of the bank directors he is absent.
In the excitements of the political canvass he fails to be at the place appointed.

What is the matter?
His health has broken down.

The train halts long before it gets to the station.
