If the subject of the verb in the first deck is not written, it should be the first word of the second deck, as,
INVESTIGATE
WET VICTORY
Texas Senators All Agreed
to Inquire Into Late
Election.
Omit all forms of the verb to be whenever possible. This head,
ASKED HOW HE GOT
STOLEN AUTOMOBILE
is more effective than this,
IS ASKED HOW HE GOT
THE STOLEN AUTOMOBILE
Avoid expressions that are awkward because of omission of some form of the verb to be such as this:
U. S. WEATHER MAN
SAYS SUMMER HERE
Negatives should be avoided. The head should as a rule tell what happened, not what did not happen.
Avoid the word may. The head should as a rule tell what happened, not what is going to take place, perhaps.
