Ivy Day is here again so after two weeks of basically exhibition predictions it's time for the real thing. I regret that I haven't been doing better than 600 in my picks, but those of you who follow the comes will notice that for the first time in modern comic strip history, the Jackson Twins were wrong too. And it Jan and Jill can give some bad advice. I figure those of us who are less perfect are entitled to an occasional error.

Many have secured me for my recent failures and I would like to acknowledge if not gratefully notes from Steve Shalen 71 and Bob Kamilli A 1969 graduate of Rutgers, who wished to rub salt into open wounds. One fellow offered to bet me on any picks this week but I told him he must be kidding. I predict a perfect percentage today.

YALE-BROWN: Running Bear loved Little White Dove Johnny Presston said so. But this legendary Indian will not be so kindly towards the little white dove Elis today when Yale will lose its first Ivy League game since 1966. Brown is missing some key players and Yale does have a pretty good defense against rushing. Also, Yale's Massey to Milligan passing combination isn't bad. But the Bruins are hungry after last week's bad breaks and they have a bit too much on both offense and defense for the Bulldogs to pull out a victory on this sunny day in Providence. The Elis were lucky last Saturday but not this afternoon so I pick Brown 21-14.

CORNELL-PRINCETON: Rutgers beat Princeton, 29-0 but Rutgers beat Cornell by only 21-7. But don't let that fool you; it didn't fool me. There's going to be a lot of running in today's game and Cornell's Ed Marinaro will do a good bit of it. Princeton, however, has a bit more talent and is improving faster than Cornell. It'll be surprisingly close for the old Tiger alumnus, but they'll smile to the tune of 21-17.

DARTMOUTH-PENN: Clark Beier is gone, but so is Bernie Z. Dartmouth is better all around than the Quakers and the game is being played in Hanover, N.H., while the Astroturf in Philadelphia rests up. The Indians will jump off to a quick lead, and the Quakers' attempt to recover will be too little too late. It'd b great if Penn could win, wouldn't it. The Big Green, 28-14.

COLUMBIA-HARVARD: Imaging a beauty contest between the waitresses at Hazen's and a group of bunnies from the Boston Playboy Club after the bunnies got run over by dirty old men in Mack Trucks. The bunnies would win anyway, right? So it is today in Harvard Stadium. The Crimson is missing some big boys, like G. Farneti, and F. Martucci. But that still leaves the Crimson far ahead of the Lions, who wish they had someone that good to get injured. You Know? So maybe our guys will wise up today and splurge on desire. Maybe Dave Smith's ready. The best I can do is 21-7, Harvard.

ORIOLES-METS: If the Mets can beat the Braves as badly as they did, there's no reason to think that they can't do worse damage to the overly swelled egos of the Baltimore team. And New York teams just don't lose to those from Baltimore, even when the odds-makers instruct them to. As for today's game, there is no way they can beat Tom Seaver, originally a Braves product who is a fine young pitcher. The New Breed to win, 4-2. My Red Barber autographer, obtained when the Old Redhead came to Mt. Kisco for a wedding, is on the line this time.
