     Nearly 600,000 Americans lost their jobs this past month, pushing the nation's unemployment

rate to 7.6 percent. But not all of those fired workers are sitting at home, reading the want ads

and waiting for the phone to ring.  Thousands are returning to school, making public colleges

and universities among the few bright places in a disappointing U.S. economy.

     For example, when many Americans have had their work hours decreased, or even lost their

jobs, Sherian Huddleston in charge of the enrollment (注册) of new students at Middle Tennessee

State University(MTSU) is working overtime. The university's population grew by 800 students this

term--an increase of 4 percent over last spring's registration. Huddleston says seeing enrollments

rise in a failing economy is not unexpected. "When people are out of jobs," she points out," they

will look at 'What else can I do?" What other career can I follow?' and they will often go to school

or return to school if they have not previously completed their degree."

     Older returning students aren't the only ones increasing enrollment at Middle Tennessee State.

Huddleston says she's also seeing an increase in student transfers. "Students who previously went

out of state to more expensive schools, or even in state to more expensive, maybe private schools,

because of the economy those students may be transferring to public schools, the state schools, to

make the most of the lower cost of attending," she explains.
