Over 400 Harvard students rolled up their shirtsleeves on Saturday and worked on one of 16 different community service projects organized by Har'd CORPS, a community service organization started by Stephen N. Smith `02.

The day began with breakfast outside the Science Center, courtesy of Harvard University Dining Services (HUDS).

At 10 a.m., the participants split off to work on their separate projects.

Forty students handed out leaflets at major Boston destinations describing an upcoming AIDS walk sponsored by Aerosmith.

Forty Harvard students cleared 20 cubic yards of trash from the Alewife Reservation-100 acres of swamp, forest and fields housing hundreds of species of animals. They exhumed tires and shopping carts, a 300-pound safe, a steel gallon drum and even a kitchen sink.

The Hyde Park Community Center, which offers continuing education classes for adults and afterschool programs for children, asked Har'd CORPS to repaint their teen center.

Volunteers signed up as individuals or as teams. Margaretta E. Homsey '04 cleaned nature trails with Horizons for Youth, an organization that takes inner-city youth into the wilderness for a week of hiking.

Emilie S. Fitzmaurice `04 picked the 16 projects from a list of around 70 that she compiled. Projects had to be close by, fun and "hands-on," she said.
