Mercer's House [c.1842-????]
Describing Hong Kong is 1843
From a lecture by the Rev. JAMES LEGGE, D.D., LL.D., on reminiscences of a long residence in the east, delivered in the City Hall, November 5, 1872.
Arrived at the Happy Valley, there were to be seen only fields of rice and sweet potatoes. At the south end of it was the village of Wong-nei-ch'ung just as at the present day , and on the heights above it were rising two or three foreign houses, with an imposing one on the east side of the valley, built by a Mr. Mercer of Jardine, Matheson and Co.'s House. All these proved homes of fever or death, and were soon abandoned.
