The observing weather was poor for the month and though work was carried out on 18 nights or parts of nights during the month only 101 spectrograms were obtained.
Director J. S. Plaskett obtained 28 spectrograms on 1 1/2 nights. Absent from the 14th to the end of the month to attend the meetings of the Royal Society in Ottawa and also to transact Departmental business there.

Research Astronomer W. E Harper obtained 26 spectrograms on 4 nights and measured 4 for radial velocity. Day work was almost entirely devoted to the absolute magnitude program, obtaining the final curves relating line intensity with absolute brightness. Performed administrative duties with the absence of the Director.
Astronomer R. K. Young obtained 16 spectrograms on 4 nights. Day time was spent on working up the relations between line intensity and type and line intensity and absolute magnitude.
Assistant Astronomer H. H. Plaskett obtained 8 spectrograms on 1 1/2 nights. He prepared for publication Volume II, Number 12 “the Wedge Method in Spectrophotometry”. Leave from the 13th to the end of the month.
Temporary Assistant W. H. Christie obtained 23 plates on 7 nights. Searched all the periodicals in the Observatory Library to obtain information as to the radial velocities of stars. Entered same on Observatory Card Catalogue.
Clerk-Stenographer Miss H. R. Keay handled the usual plates, correspondence, etc. Typed the Colonist articles and Volume II , Number 12 of the Publications of the Observatory. Proof read the Descriptive Booklet on the Observatory. Prepared Volume II, Numbers 7, 8, 9 for mailing. She spent time transferring the record of periodicals to new loose leaf book.
