Susan Purcell and her college room-mate, Susan Ziglear, were busy unpacking their belongings - clothing, two clock radios, a stereo, a television set, a popcorn popper, a toaster, homemade cookies, a hot pot, electric hair curlers, a curling iron and a hair dryer.

"Most of the stuff is hers," Purcell said pointing a finger at Ziglear in the dormitory room at Marymount College in Arlington yesterday.

Purcell and Ziglear, both freshmen, are typical of today's college students who according to one college official, "bring everything under the sun" to campus.

Helen C. Rainey, secretary to the dean of students at Marymount Collebe, laughed. "You name it. They've got it," sge said. "This is the affluent society. We used to limit the number of electrical appliances they could bring, but no any more."

"When I went to school (about 13 years ago), you had just a suitcase and a trunk." said Linda McMahon, dean of students. "I think what we're seeing today ist typical of all college campuses," she said.

"I would say the stereo is the piece of equipment," McMahon said.

Cars and at least one truck loaded with suitcases, trunks, bicycles, plants, tennis rackets, skis and all types of electrical appliances - including small refrigerators - pulled into the parking lot in front of Gerard Phelan Hall at Marymount yesterday.

"We're helping my sister move in," Cathy Quinn said proudly as she and her mother, Ann, carried a color television set into the dormitory.

"I heard they have ski weekends," said Gina Quinlan of Holland, Pa., as she held skis in one hand.

"Almost every luxury they can think of comes," said Megan Jersey, a sophmore resident assistant who was helping to supervise the freshmen yesterday at the private, four-year institution with an enrollment of 800. "We have all of the 'essentials' that we could probably do without."

"They want all the comforts of home here," said Dolores Corson of Fairhaven, N.J., who was helping her daughter, Karen, get settled.

"She (Karen) was talking about one of those little refrigerators," said Mrs. Corson who added that she thought the refrigerator would be a bit too much.

"They will have to rewire the Hall," Warren Corson said jokingly as he watched the different conveniences that his daughter and her college mates were bringing into the mormitory.

Olga Solores, a dorm student leader, said that, although the students are not limited on how much they can bring, "we ask them to think of the other person."

Some of the students were in fact doing just that and had coordinated with their roommates just what each would bring.

"My roommate is bringing the stereo," said Connie Quinn, who brought records and a color television set.
