The only independent city public school system was that of Mobile, organized in 1852, after northern models. The Boys' High School in this city was kept open during the war, though seriously thinned in numbers. The lower departments and the girls' schools were always full.[596] The state system of schools was organized in 1855 on the basis of the Mobile system. It was not in full operation before the war came, though much had been done. During the first part of the war public and private schools went on as usual, though there was a constantly lessening number of boys who attended. Some went to war, while others, especially in the white counties, had to stop school to look after farm affairs as soon as the older men enlisted. Teachers of schools having over twenty pupils were exempt,[597] but as a matter of fact the teachers who were physically able enlisted in the army along with their older pupils. The teaching was left to old men and women, to the preachers and disabled soldiers; most of the pupils were small girls and smaller boys. The older girls, as the war went on, remained at home to weave and spin or to work in the fields. In sparsely settled communities it became dangerous, on account of deserters and outlaws, for the children to make long journeys through the woods, and the schools were suspended. The schools in Baldwin County were suspended as early as 1861.[598] Legislation for the schools went on much as usual. After the first year few new schools were established, public or private. Appropriations were made by the legislature and distributed by the county superintendents. When the Federals occupied north Alabama, the legislature ordered that school money should be paid to the county superintendents in that section on the basis of the estimates for 1861.[599] The sixteenth section lands were sold when it was possible and the proceeds devoted to school purposes.[600] A Confederate military academy was established in Mobile and conducted by army officers. The purpose of this institute was to give practical training to future officers and to young and inexperienced officers. Few, if any, of the schools were entirely supported by public money. The small state appropriation was eked out by contributions from the patrons in the form of tuition fees. These fees were paid sometimes in Confederate money, but oftener in meat, meal, corn, cloth, yarn, salt, and other necessaries of life. The school terms were shortened to two or three months in the summer and as many in the winter. The stronger pupils did not attend school when there was work for them on the farm; consequently the summer session was the more fully attended. The school system as thus conducted did not break down, except in north Alabama, until the surrender, though many schools were discontinued in particular localities for want of teachers or pupils.
