In a letter circulated to all house residents about the most recent incident, Mather staff asked students to call the Harvard police's anonymous tips line if they had any information about the graffiti.

"It is increasingly impossible for me to believe that other students do not know about this," said Senior Tutor Mary K. Peckham.

Meanwhile, members of four Black student organizations--the Black Students Association, the Association of Black Radcliffe Women, Harvard Society of Black Scientists and the Freshman Black Table--mobilized to show their concern for the recent racial incidents.

"It was a joint collaboration," said Valencia D. Thomas '96, president of the Harvard Society of Black Scientists. "My roommate and I were discussing it, and we decided we should go down and make a representation."

Many Black students not only condemned the racist acts but also wanted to show their support for their fellow Blacks in Mather.

"We felt the need to come out against racial epithets, racial slurs and racism in general," said Cynthia D. Johnson '96, president of the Association of Black Radcliffe Women. "And also just to say to the Black community of Mather that when one member of our community is affected by racism, all of us are affected."

Penningroth expressed dismay for the lack of reaction from her fellow Mather residents.

"What disappointed me the most was the apathy with which students in Mather House responded," Penningroth said.

But many Mather residents said they were upset by the latest in the string of racial incidents.

"It just pissed me off," said Chris R. Calabrese '95, who walked by the graffiti Saturday. "It pretty much ruins your whole day."

"It's embarrassing to the house," Calabrese added.

Like many other residents, Calabrese believes that one individual is behind the string of slurs.

"It seems to me like it's one very upset person who's crying for attention," Calabrese said.

Gavin expressed a similar opinion. "In my opinion, you are dealing with one person, one isolated individual, not a pervasive attitude in the house," Gavin said
