The UC Ag College circular of June, 1907 announced Wednesday, October 2, 1907 as the first day of instruction at the brand-new University Farm in Davisville, California.
Alas, according to Ann Scheuring in Abundant Harvest, because of construction delays the planned instructional program had to be "postponed for a year." (p. 27.)
October 2 was, specifically, the first day of the first of seven “short courses” planned for 1907-08. This course was called “Dairy School” and ran from October 2 to November 28.
This and the six other short courses are described in some detail in that June, 1907 circular, which is reproduced here in its entirety.
