Quicker than you can say "Robert L. Isom," Ivy League football became as thick as a Quincy House tapioca Saturday, as Yale, Brown and Dartmouth all posted wins.

The Elis (3-1 league, 4-2 overall) shot the three-way tie for the first place by virtue of their 27-12 win at home over Penn (2-2, 2-3). Yale came back from an early 14-0 deficit behind the 38-for-158 rushing of tailback John Pagliaro to defeat the rejuvenated Quakers.

Penn's wishbone offense churned out 270 yards on the ground against the stingy Blue defense, but Yale's all-around attack prevailed in the end.

Up in Hanover, Dartmouth (3-1, 5-1) destroyed new Cornell coach Bob Blackman's hopes of defeating his former charges. Putting themselves back into first place with the 17-13 triumph.

Cornell (0-4, 0-6) opened a 7-3 lead in the second quarter, but then reserve Big Green quarterback Buddy Teevens took over the helm to lead the Woodsmen to victory. Teevens got a little help from running backs Curt Oberg and Sam Coffey, who combined for 156 yards rushing.

Brown (2-2, 4-2) crushed Holy Cross, 44-13, in a non-league contest, but found itself in a second-place tie with rising Princeton and slipping Penn.

The Bruins rolled over the Purple defence for 342 yards via the turf. with Joe Jamiel, Marty Moran, Seth Morris and Mark Whipple each striking for long gains. Whipple riddled the Holy Cross defense with his arm, too, tossing 19 bullets for 14 completions and 151 yards.

Columbia coach Bill Campbell told his players to go out on the field and have some fun before the Lions' (1-3, 2-4) contest against Lambert Trophy leaders Colgate. The Red Raiders had more fun, though, blasting their way to a 48-36 win.

Colgate halfback Henry White needed only 11 plays to dance past the Lion defense for 204 yards and three touchdowns. White's teammates also punched out a little yardage, as the Hamiltonians compiled 667 yards on offense.

Stay tuned next week, same time, same channel. In 1977, as in all years, the Ivy picture remains in a state of flux.
