While the first week or ten days was somewhat broken, the remainder of the month was clear practically every night. Observations were made on 27 nights and 183 spectra secured as compared with an eight-year average of 26 nights and 215 spectra.
[The Province of BC built the road up Observatory Hill as part of their contribution to the construction of the Observatory. It wasn’t until July 1927 that they relinquished control of the road to the Federal Gov’t. The road was paved in 1932 as a works project during the Depression, Ed]
