PATHOGENIC EFFECTS OF THE EARTHQUAKE, 
A curious and fortunately trivial effect of the earthquake was the production of nausea. 
This was observed especially in the region of slower motion of the earth, beyond the 
zone of destructive effects, but one or two cases being reported from the region of 
high intensity. The sickness produced was in most cases apparently similar to sea- 
sickness, and ascribable to the swaying of the ground. In the few cases which occurred 
in the region of quick motion, the nausea was more probably due to nervous shock. 
Brief mention is here made of the cases reported, tho there were probably many others. 
At Ruby, in Siskiyou County (R. E. Madden), intensity III-II, persons were slightly 
nauseated or rendered dizzy, but the feeling past instantly. At Upton, Siskiyou County 
(EK. R. Dixon), intensity IV-III, people felt seasick. Mr. J. H. Roberts, of Yuba City, 
intensity VI-V, reports that 5 persons on his place were made quite sick. In Marys- 
ville (R. F. Watson) the shock caused a dizzy feeling. At Stockton (. Hughes), in- 
tensity VI, a considerable number of people suffered from nausea and dizziness, with 
headache, for a time after the shock. With some these disagreeable symptoms per- 
sisted all the following day. At Modesto (KH. Hughes), intensity VI, a number of 
people were affected by symptoms somewhat like those of seasickness for several hours 
after the shock. San Francisco (Miss F. Locke). Mrs. E. was nauseated by the earth- 
quake and felt pains in her heart. Several people were nauseated by the motion of 
the ground at Pescadero, San Mateo County, intensity VIII-VII. (G. A. Waring.) 
In Bear Valley, San Benito County (G. A. Waring), intensity VI-V, a man out-of- 
doors became dizzy and nauseated, but did not at the time realize the cause. Thru 
the south end of the valley several people became dizzy. Between Mendota and Coa- 
linga (G. F. Zoffman), intensity VII-VI, many persons suffered from a nauseating sen- 
sation. At Conejo, Fresno County (E. Pickett), intensity VI, the earthquake made 
some people sick at the stomach. At Santa Barbara (J. A. Dodge), intensity III, a 
woman who was out-of-doors at the time of the shock was made slightly dizzy. In 
Gardnerville, Nevada (J. A. Reid), intensity IV, a number of people complained of 
a feeling of nausea while eating breakfast at the time of the earthquake, but they felt 
no motion. At Yerington, Nevada (G. D. Louderback), intensity IV—III, one person 
experienced a dizzy sensation. At Lone Pine, Nevada (M. 8. Dearborn), intensity IV, 
a good many people when they first felt the shock thought that they were simply dizzy. 
EFFECT OF THE EARTHQUAKE ON ANIMALS. 
Miss Finette Locke, of Santa Cruz, has interested herself in an inquiry into the be- 
havior of animals at the time of the earthquake, and has prepared lengthy notes reciting 
incidents which were reported to her as the effect of the main shock and the after- 
shocks upon animals in various parts of the Coast Ranges extending from Santa Rosa 
to Santa Cruz. Her notes, which refer chiefly to domesticated animals, form the basis 
for the following summary statement: 
Horses. — Horses whinnied or snorted before the shock and stampeded when the latter 
was felt, some falling owing to the commotion of the ground. Horses in harness became 
frightened and ran away, while others stopt and screamed. Some horses with riders 
in the saddle stumbled and fell; others stood and shivered. A mule near Santa Rosa 
refused to eat all day. A farmer in the same neighborhood observed his horses moving 
about, whinnying and snorting, and called to his boy, who was with them, inquiring 
what was the matter, but before the boy could answer he felt the shock. In a stable 
of 30 horses on Alabama Street, San Francisco, all reared, snorted and jumped before
