It is ammunition which tells.

One single blast of it, fired in the direction of a laundry in Portland, Oregon, two years ago, performed the wonderful feat of blowing a large hole through the Fourteenth Amendment to the Constitution of the United States.
There was a law in Oregon which decreed that the working day of women in factories and laundries should be ten hours long.

The law was constantly violated, especially in the steam laundries of Portland.

One night a factory inspector walked into the laundry of one Curt Muller, and found working there, long after closing time, one Mrs.Gotcher.The inspector promptly sent Mrs.Gotcher home and arrested Mr.Muller.
The next day in court Mr.Muller was fined ten dollars.

Instead of paying the fine he appealed, backed up in his action by the other laundrymen of Portland, on the ground that the ten-hour law for women workers was unconstitutional.
