In 1912, about 1,000 children attended Roslyn Public School Distirct #24, more  than Roslyn's total population today. During the boon days in the early 1900s, Roslyn was the largest city in Kittitas County with more than 4,000 citizens.

Coal mining attracted scores of new immigrant families which led to the construction of a new high school on the district's school complex on Third and Idaho. The high school joined the eight-room Primary building and a six-room Central (middle school) building. Completed in 1910, it featured the very latest in modern education: science laboratory, domestic science and manual training rooms as well as a gym and assembly rooms.

The school was torn down in 1937 to make way for a new school building that still occupies that site. Below: Another group shot of the Roslyn Public School #24 taken May 1914 in front of the Primary building. High school students were housed on the top floor until a new high was built in 1910.
Above:: IF THE UNITED STATES WAS A MELTING POT of nationalities at the turn of the century, then Roslyn was its first course. Coal mining attracted immigrants from western, central and eastern Europe including Russians, Poles, Ukrainians, Lithuanians, Croatians, Hungarians, Serbs, English, Welsh, Scottish, Swedish, German and Italians. Imagine 24 nationalities and almost as many languages in one school as pictured in this early 1900s photo. Below: Turn of the century class photo pictured in front of the school. Note the student in the second row holding her doll beside her.

Above: ROSLYN'S NEW HIGH SCHOOL UNDER CONSTRUCTION in 1909. Thirty years later, the structure was torn down and replaced by a new school funded by WPA money under FDR's New Deal . But  Roslyn's days as a coal town were numbered as trains converted to diesel and electricity. As the population waned, students were eventually  consolidated into the Cle Elum Roslyn School District. Below: Roslyn's Primary and Central School on Third and Idaho.
Above: GROUP PHOTO OF ROSLYN HIGH SCHOOL'S 1909 GLEE CLUB which included the four senior girls who were the first to graduate from Roslyn's four-year high school. Before 1910, high school student's had been housed in the upper story of the Primary building, but by 1909, population increases justified construction of a separate building.
