Sumner High School also maintains[106] a normal training course for its girl graduates. The Cottage Avenue graded school is under the supervision of the High School principal and it serves as an observation school for those taking normal work. This high school also maintains an evening school. In 1915-16 the enrollment was 457. The Negroes of St. Louis are very proud of their high school, and it is well patronized. In 1915-16 the enrollment[107] was 811 and in 1916-17 it passed the 1,000 mark. There were employed in this high school in 1915 thirty-five teachers who received an average salary of $127 a month. The school has a library containing about 2,000 volumes and equipment[108] valued at $30,000. The Lincoln High School of Kansas City, although it is not as large or as well equipped as Sumner High School, is nevertheless a good high school. The first Negro high school[109] was opened in the Lincoln Grade School Building. A high school building was erected on Eleventh Street in 1890. This building was used as such until the erection of the present high school, the site of which was purchased in 1899 and the new building was opened September 6, 1906. In 1915 this school had an enrollment[110] of 462 pupils. Seventeen instructors were employed at the average salary of $115 a month. Besides the regular high school courses, this school has departments of domestic science and domestic arts for the girls. Vocational courses are open to the boys and a course in military training has recently been opened for the boys. In 1915 the equipment[111] of the school was valued at $10,000. The library contained a number of valuable works.
