WASHINGTON (AP) _ The new chairman of the Copyright Royalty Tribunal co-authored a book that says black Americans are clinging to their ''jungle freedoms'' rather than adopting the work ethic.

Marianne Mele Hall, scheduled to appear today before a House subcommittee, is listed with two other authors on the title page of ''Foundations of Sand: A Hard Look at the Soft Sciences,'' a 71-page collection of eight essays published three years ago.

An essay called ''The Minority Problem'' states that ''in our ghettos, there remain many blacks who still hold to their African traditions ... They insist on preserving their jungle freedoms, their women, their avoidance of personal responsibility and their abhorrence of the work ethic.''

The Senate confirmed Ms. Hall, a lawyer, to her $70,000-a-year job April 2. The Copyright Royalty Tribunal regulates rates paid by cable television operators to rebroadcast movies, television shows, sports events and other programs.

The title page of ''Foundations of Sand'' lists Lawrence Hafstad as the main author of the work. The names Marianne Mele and John Morse appear below Hafstad's name.

Other essays in the book discuss the American worker, American labor unions and ''the need for a stratified society.''

The essay on minorities criticizes ''our sociologists'' for insisting that school busing could solve the minority problem. ''Could the differences between race horses and draft horses be eliminated by their living and training together?'' the authors ask.

They also condemn the same sociologists for putting blacks ''on welfare so that they can continue their jungle freedoms of leisure time and subsidized procreation.''

The ultimate solution, according to the authors, is ''a separate but superior (education) system for blacks, tailored to their special needs.'' They say the system should reward blacks who ''accept the work ethic and qualify for integration in the majority schools'' with ''taxi rides and similar honors.''

The national school system for blacks should have all male teachers ''and it probably would be wise to have retired star athletes as principals,'' the essay said. ''Such support would be an investment rather than charity.''

Ms. Hall, who listed herself on a Senate form as co-author of the book, told The Washington Post that ''I edited that work, period. Those are Dr. Hafstad's ideas.''

In an interview published in today's editions, Ms. Hall was sked if she agreed with the ideas in the book. Ms. Hall told the newspaper she was not qualified to comment on scientific concerns.

Asked why she didn't leave her name off the work, she replied, ''If I wash a floor real well, I'll take credit.''
