Catholic University is dropping Howard from its basketball schedule after the 1978-79 season, it was learned yesterday.

The five-year contract concludes then. Howard coach A. B. Williamson said he called Jack Kvancz, CU's coach and athletic director, two weeks ago in aneffort to extend the contract.

"He said, 'Nothing doing'," Williamson confirmed last night. "He's calling the series off. He's doing the same thing that Lefty (Maryland coach Lefty Driesell) is doing to George Washington."

The Maryland-GW series ends after this season, coming after GW's first victory over the Terps in 17 years and GW's refusal to switch the regular - season game to becoming a participant in a season-opening tipoff tournament.

The Howard. Cu game has been the season opener for both schools.

Kvancz said that CU had contracted to play Holy Cross as its season opener for the 1979-80 and 1980-81 seasons.

"It was the opportunity to play Holy Cross," Kvancz said. "It's a national school. It's a Catholic school and the alumni are happy to see us play them.

"If we beat Howard, they say, 'So what.' If they beat us, people say we're bad. If we lose to Holy Cross by five points, people will say we've accomplished something."

CU-Howard relations became strained last season after the Bison won the opener. At the time, Kvancz complained about the officiation of the referees assigned by Howard's Mid - Eastern Athletic Conference.

Leo Miles, Howard athletic director, responded by calling Kvancz a racist for blaming the officiating as the reason his team lost to a predominantly black school coached by a black man.

Howard has been trying without success to schedule area schools Georgetown, George Washington, American and Navy. Only Catholic among area Division I teams has played Howard.

"I remember what Dean Smith (North Carolina Coach) said last year,D, From D1) attributing it to Adolph Rupp (the former Kentucky coach). "You never let a little guy get big.'" Williamson said. "People think we are very bad or people think we are growing too much."

Williamson said Kvancz action surprised him.

"I'm an advocate of area games," he said. "It's tough for us to schedule area games. I'm glad just to go down to GW and scrimmage them, as we did last week.

"We play everybody in volleyball, in soccer, in baseball, in all the minor sports. But when you ask about a basketball confrontation they always say, "Nothing doing'."
