The service is the first Catholic mass to take place in the Yard for at least 20 years and the priest was the only person other than House masters and administrators to enter Mass. Hall since Wednesday.

In addition, on Friday night, members of Harvard Hillel brought challah and wine to share with protesters at a service celebrating the beginning of Shabbat.

Building Support

PSLM members have also garnered significant support from those within the University, extending from House masters to undergraduates.

As administrators, masters are allowed to enter Mass. Hall, and the masters of Adams, Cabot, Eliot, Leverett and Lowell Houses have come by to visit students and offer their support.

The masters also composed an open letter last night urging administrators to negotiate with students.

The masters hope the letter will "provide a foundation for reconciliation," Eliot House Master Lino Pertile said yesterday.

Pertile visited the students occupying Mass. Hall briefly Saturday.

While the students seemed comfortable, he said he hopes that the University soon reaches some resolution.

"They are there because their conscience compels them," he said. "They'd rather be playing in the sun."

For those concerned about quality of life in the Houses, Pertile said the living wage issue is difficult to ignore.

"In the Houses the living wage issue has a human face," Pertile said. "We are in touch and our students are in touch every day with very low-paid workers."

And student support has grown increasingly more visible since Friday with the creation of "tent city"-20 tents, banners and messages of support for the living wage campaign drawn on the cement in colored chalk. More than 50 students have slept out the past three nights.

Hand-written messages from the students inside Mass. Hall hang on string around the tents.
