During the period 1859 to 1894 secondary school classes were held separately for boys and girls. The classes for boys were held in the Leh's store building on Hamilton Street, and the girl's classes were held in the Sunday School rooms of the First Presbyterian Church on North Fifth Street. Classes were transferred to the Fourth Ward Wolf Building from 1880 to 1894. Classes were moved in 1895 to a new building built exclusively as a high school erected at the site of the "Old Central School", at Lumber and Turner streets. However, it became overcrowded with students and in 1913 five rooms of the Herbst School Building were used for the freshman class of 1918.
