NEW FOOTBALL RULES AFFECT
SEASON IN ROCKY MOUNTAINS
Many Important Changes Noted in 1910
Official Guide--Study Them Hard Now

Spaldlng's official football guide
for 1910 is about ready for the book
stores. and within the next few days
the lovers of the gridiron sport will
have an opportunity to look over the
records of last years campaign.
Among the interesting reviews is that
relative to the season in the Rocky
mountains. All football fans are in
terested in the new rules. and the
guide has some interesting things to
say about them. as follows:
The changes in the rules for 1910
must be carefully noted by officials,
coaches. captains and players in or
der that they may fully understand
what is expected.
Taking the rules up in order the
first change noted is in the diagram
of the field, the longitudinal lines
now being ommitted, because as the
quarterback may cross the line of
scrimmage at any point, and as the
forward pass may be thrown over the
line at any point, these longitudinal
markings are no longer necessary.
Hence. Rule l.. section 2, now simply
reads that the field shall be marked
off at intervals of five yards with
hllllt llllfE lhldilti W INC t1bhA AlAi'7'
The next rule affected is that re-
garding substitution. A rule has
been passed that a player who has
been removed for any cause except
disqualification or suspension may be
returned to the game once at the
beginning of any subsequent period.
The game is divided into four pc
Rods of | : minutes each, so minutes
in all, with the usual intermission
between the second and third periods,
but n three-minute intermission only
between the first and second and
third and fourth periods. During
this short lntermission of three min
utes. no player is allowed to leave
the field of play. nor any representa-
tive come on the field. except one
who looks after the physical condi-
ton of the players. At the beginning
of the second and fourth periods, the
teams change goals, but the posses
sion of the ball the down. the rela-
tive spot of the down, and the dis
tance to be gained all remain the
same as al the termination of the
preceding period The teams do not
change goals after a try-at-goal fol-
lowing a touchdown, or after a goal
from the field, but the side scored
upon then has the option of kicking
off, or having their opponents Kick
off
Crawling has been defined as an
attempt to advance the ball by the
runner after the bill is declared dead
and 's perali2ed. Seven players of
the side holding the ball must be on
the line of scrimmage. The player
who first receives the ball when 1t is
snapped back may carry ii across the
line of scrimmage at any point.
The legislation regarding q for
ward pass should be read over re-
peatedly by officials, coaches, cap
tains and players in order that 1t
may be thoroughly mastered. First,
the lines to be observed should be
thoroughly borne in mind. There are
two lines of scrimmage, one for each
side. as formerly. the line passing
through the end of the ball A man
TO be on the line of scrimmage must
be within one foot of this line, but
player to be eligible to receive a
forward pass must be at least one
yard back of his own line of scrim-
mage and no one may receive a for
ward pass who is not thus one yard
back, or occupies the position on the
| end of the line of scrimmage, There
is another imaginary line in addition
to this one-yard line. and that is five
yards back of the line of scrimmage.
No man may make a forward pass,
nor may he kick the ball unless he is
behind this imaginary five-yard line.
Between this line and his scrimmage
line he is allowed to neither kick nor
make a forward pass. There is still
another imaginary line, and that is
on the other side of scrimmage, the
defensive. This is line twenty
yards back from the defensive line OF
scrimmage and within the space
lbounded by the scrimmage line and
