Large room with wood floor and wood counters down the middle and along walls

Dr. Ralph Parker’s laboratory/office, east side view, circa 1921. On the table built around the column was a scale encased in wood and glass to keep air movement from affecting the weighing of small amounts of material. To the left of his desk was the reference library, while to the right was some chemical storage. A candlestick telephone sat on the desk in front of the window. Boxes and card files of records were piled on the center map counter.

Other side of large room with wood counters and shelves and three large windows

The laboratory/office of Dr. Ralph Parker overlooking the car shed outside, circa 1921. The map counter in the foreground was a necessity; keeping track of where cases of Rocky Mountain spotted fever occurred and where different kinds of ticks were found was an important part of the research. A microscope illuminator was set up just below the window on the left—it looked like a camera.

corner with counters on both sides

...

The far corner of the office/laboratory, circa 1921. Rows of chemicals stood on shelves above the map of Rocky Mountain spotted fever cases. Next to the glass bell jar instrument cover were likely metal canisters containing pipettes. The white unit on the counter-top is either a double-walled hot air sterilizer or an oven for drying glassware. Next to that a copper retort is connected by its neck to a zinc condenser. The liquid in the retort was heated and the condensation ran into the condenser, where it was cooled to make a refined liquid. This was an old-fashioned way to do laboratory distillations even in the 1920s, but it produced a good amount of liquid. The Canyon Creek Schoolhouse laboratory would have had to fill out special paperwork for the U.S. Treasury certifying why they were using it; such distillation set-ups were commonly used as stills by bootleggers during the years of Prohibition.

Rows of cages on racks in animal room

The guinea pigs used to feed the ticks were kept in an animal room on the upper story of the Canyon Creek Laboratory. Those that were healthy had to be kept separate from those who carried the Rocky Mountain spotted fever bacteria.

A desk and chair with closet and metal heater

A work area behind the cages included the operating table under the window, a desk and chair, and a shower in the corner. The operating table was where ticks were taken off or put on the guinea pigs. The large canister between the windows was most likely used to heat water for the shower.
