Twenty-five high school students from Frederick, Maryland, will tour the College tomorrow with members of Newton High School at whose homes they are guests. The 13 boys and 12 girls arrived on Friday and will remain a week in the second annual student exchange fellowship.

Two weeks ago members of Newton's high school went to Maryland and spent a week with Frederick High School students. On this return trip the visitors will tour Boston and vicinity to sample the "Yankee" hospitality, and see historic sites.

Saturday and Sunday the Southerners stayed at the houses of their Northern friends for a Reunion and a dance. Tonight the sightseers will attend the "Topa" concert in Boston.
