Tan leather notebook measuring 5" x 8". Very good with abrasions and edgewear. A notebook compiled by J.A. Garrett while studying at the University of Michigan in the early 1900s. Garrett's notebook includes in depth experiments and lessons pertaining to steam engines featuring detailed drawings and charts. It is additionally illustrated with 5 cyanotype photographs of the engines he worked on. It appears the notebook was handed in for assignments and some pages include a color pencil comment from the professor such as "ok" and "neat work." The experiments are written out in extensive details explaining all of the steps involved in the experiment, the hypothesis, and the outcome. One of these entries, accompanied by a cyanotype image of an engine reads, "Experiment No. 19 Friction and Mechanical Efficiency Test of Lansing Engine. Non-Condensing, Automatic 1904." It continues, "In this experiment with the engine running automatic, non-condensing, the speed of the engine did not drop to such a marked degree as with the throttling. The difference between throttling and automatic is in the control of the amount of the entering steam." This entry is followed by graphs and charts illustrating their findings. Garrett graduated in 1904. Bestandsnummer des Verkäufers 444133
