    The regular autumnal appearance of bubonic plague in villages previously attacked or in those situated nearby strongly suggests an aetiological role of rodents, especialy rats. Conditions are certainly favorable for the latter: The houses built in or against the mountain sides offer ideal nesting places while ample food is available in the shape of enormous grain supplies kept by the villagers (11). Besides these domestic rodents a species of ground squirrel is said to occur (Watson, 1928). A high mortality among rats seems to have been present during the 1919 outbreak. More definite evidence procured during the 1928 epidemic will be discussed soon. Suspicious outbreaks (some confirmed) since 1917 may be tabulated as follows : Year Locality • No. cases Remarks 1917 (autumn) P ei chia tsui (10 M. H ^ east of Yellow River) Ca. 70 Few recoveries.
