The anniversary exercises of the Theological Department of Howard University, (which is largely aided by the American Missionary Association), occurred on the 7th inst., in Washington. The spacious and beautiful edifice of the New York Avenue Presbyterian Church was freely offered for the purpose, and was filled with a large audience of white and colored people. Such an event could not have taken place at any former time, and it marks the rapid and healthful progress of public opinion. Six of the graduating class made addresses, which were a credit to themselves and to their race, and elicited the commendation of many intelligent gentlemen and ladies who heard them. Sixteen students were sent forth to preach, all of whom go to the South, to the Freedmen. Five of these had pursued a full course of study, including Hebrew and Greek: the others had received training in English studies only. Fifty theological students have been under instruction in this department the present year. Each graduate received a handsome Bible from the Washington Bible Society, and an address was delivered by Rev. W. R. Harrison, D. D., chaplain of the House of Representatives, and pastor of the South Methodist Church in this city—a fact which marks the progress of good feeling. Never before was the promise of usefulness in this work so great. * * * * * LEWIS HIGH SCHOOL. (_From the Macon, Ga., Telegraph and Messenger._) As announced, the closing exercises of the Lewis High School took place yesterday, May 27th, and reflected credit alike upon teachers and pupils. The latter, embracing both sexes, number 110; and a more intelligent and well-behaved body of colored youth cannot be found anywhere. The singing and music were especially good, indicating great aptitude on the part of the scholars, and very careful training. This Institution is under the care of the American Missionary Association, whose headquarters are at New York. It appoints the teachers, and supplies all the funds that may be needed annually for its support. The school is under the general supervision of the pastor of the Colored Congregational Church, Rev. Mr. Lathrop, who also teaches chemistry, philosophy and book-keeping. In all of these branches, the pupils exhibited commendable proficiency. Among those who attended the examinations were Rev. Geo. McDonald, D. D., and Rev. Joseph Key, D. D. Both of these gentlemen expressed themselves highly gratified with all that they saw and heard, and when called upon, responded with neat and appropriate addresses, to the great encouragement and delight of their auditors. The Lewis High School, under the judicious management of Mr. Lathrop, Miss Christine H. Gilbert, principal, and her efficient assistant, Miss Belle M. Haskins, is doing a good work for the colored people of Macon, and should receive the countenance and support of our citizens.
