.....In 1865, the Sedalia School District (then called the "Pioneer District") became one of the first schools established in the county. It had a total of 20 pupils, quite a few considering that settlement of the area began only six years earlier, in 1859. In 1865, Douglas County's boundaries reached all the way to the Kansas border. When the county's boundaries were adjusted in 1874, Sedalia had 17 students in the school. Conditions at the school were typical of the time. The teacher and students had a bucket to hold water and one cup out of which they all drank. Heat was provided by a wood stove. The outhouse was behind the back of the building. In 1883, the teacher's salary was $45 per month, on par with the other schools in Douglas County.

.....A article from the Castle Rock Journal April 6^th, 1887 shows that a Sedalia teacher may have taken his responsibilities to have timely students a little too seriously:

.....The first wooden frame school in Sedalia may have been located near the current Post Office on the corner of Plum Avenue and Victor Street. Little else is known about this building, it was replaced by another wooden building, this time at or near the corner of Manhart and Plum Streets. The new wooden school had drop siding, which was described in Douglas County: A Historical Journey by Josephine Marr as "quite fancy for that time." When students outgrew it, the wooden building was eventually moved to a ranch, where it was irreparably damaged in 1965 by a devastating flood.

.....On July 1, 1891, the following announcement appeared in the Castle Rock Journal…

.....The stone building was one of the most advanced in the county. It contained a stoker furnace, gaslights, and running water. An addition was put on to the east in 1912, and the school could accommodate two teachers.

.....Sarah A. Gleason was fortunate enough not only to attend the Sedalia school, but also to come back and teach at it in the late 1920's and early 1930's. She and her students had picnics, went for hikes on West Plum Creek, and held Christmas plays. Miss Gleason was also partially responsible for the cleaning duties of the school, a role she did not treasure:

....."Many years later, I was teaching in a modern building that required no janitorial services on my part. I was complaining to a friend that I was tired of attending teachers' meetings… My friend, who had known me during the days of my janitorial period, remarked that I should find it much easier to attend teachers' meetings than to scrub outdoor toilets. I thought about that and counted my blessings."

.....During the cold winters, she sometimes had to carry the first graders to the outhouses so they didn't get lost in the snowdrifts. The outhouses were also a source of concern when what may have been a rabid dog wandered into the schoolyard. The teachers tried to keep the children inside the school, but when they could stand it no longer, they were sent out one by one when the dog left the area. On one of these trips, the dog returned and followed one of the boys back into the classroom. Sarah stood between the students and the dog while the children went into another room. She followed them out and they blocked the door. Eventually the dog left, and school could resume.
