Appendix F.
REPORT OF THE DIRECTOR OF THE ROYAL OBSERVATORY, HONGKONG, FOR THE YEAR 1918.
I. GROUNDS AND BUILDINGS.
The grounds were kept in order by the Botanical and Forestry Department with the assistance of the Observatory coolies.
The Battery room was enlarged in the month of April, and now serves also as a workshop.
Improvements were made to the front verandah of the Director's Quarters in May.
A new magnetic hut was completed in December. The north pillar of the new hut bears N 31° 40′ E from the north pillar of the old hut and N 85° 29' W from the nearest corner of the main building. It is distant 133 feet from the former and 292 feet from the latter.
The old hut was in a bad state of repair and required renewal. The new site is farther from the Church, the Church Hall, and the site of contemplated quarters in the Observatory grounds.
A portion of the path to the north and east of the main building was reconstructed, with concrete, in December.
A concrete path, running southward from the new magnetic hut to the path leading to the old magnetic hut, was constructed in December.
II. METEOROLOGICAL INSTRUMENTS.
Barometers. The receipt of two barometers from London, in April, a small standard Casella No 2451, and a station barometer M. O. 1409, afforded an opportunity of checking the index error of the Observatory Standard, N. & Z. 1368.
The results of the comparisons are given in the following table, together with the results obtained in former years:- Index correction of the Standard barometer of the Royal Observatory Hongkong, 1883 to 1918.
