In recent years few major colleges have cared to schedule football games with the University of Southern Mississippi or Memphis State University. The two independents have been just too tough. There was a time, for instance, when Alabama tried Southern Mississippi. Alabama lost in 1953, again in 1954, tied in 1956 and after a 1957 win decided to retire from this field with honor. Georgia had one turn, lost 14-0, and looked elsewhere. Memphis State rambled through its schedule last season without a loss. Ole Miss managed to come out with a scoreless tie and slightly bruised, but that was as close as anyone got.

As a result of its scheduling problem, Southern Mississippi lost major college status in football a couple of seasons back. It just could not get together with enough major teams. And it was confronted with the same prospect this year.

Pie Vann, Southern Mississippi coach, and Spook Murphy, Memphis coach, put their heads together the other day. They solved it. They decided they would play each other twice next fall.


The deep interest the Japanese have in unarmed self-defense—judo and all that—may yet pay off for fishermen. Tens of thousands of hatchery-raised fish are lost each year because they wander innocently into the paths of predators. No one has ever told them that their brother fish are cannibals. Now the Japanese are teaching young salmon just that.

For the past two years physiologists at Tokyo's Hosei University have been teaching young fish the art of self-defense. They use a water tank in which they put a plastic fish of adult size. Around the model they create a weak electric field of about six volts. Fifty-day-old fry are released into the tank, and when they approach the plastic fish they get a shock. Class is repeated for two hours daily until the fry learn to avoid the model fish.

To determine how well the fry have learned their Pavlovian lesson, they and some unschooled fry are dumped into a tank that is divided into two sections separated by metal netting with a mesh fine enough to prevent an adult fish from getting through but big enough to let the fry pass. On the other side of the netting a real live rainbow trout is introduced. Trained fry stay on their own side of the netting. The uneducated cross over and are eaten.

The scientists now plan to enlarge their experimentation to see what will happen in a pond and, eventually, in a river.
