ISOSEISMALS: DISTRIBUTION OF APPARENT INTENSITY. 265 
chimneys but very little destruction otherwise. No evidence of cracks could be found 
upon the side road. At a house situated at the junction of four roads about 3 miles west 
of Congress Springs, no damage was reported, tho the inhabitants were up at the begin- 
ning of the shake and say that it was accompanied by considerable rumbling and that the 
shocks which followed were preceded by a sound like a blast. 
King’s Mountain down Purisima Creek (8S. Taber). — At King’s Mountain House, brick 
chimneys were knocked down and some dishes were broken, but no damage was done to 
the house. Cream was spilt from the milk pans on the southwest side. On the Cahill 
Ridge road leading northwest from King’s along the crest of the ridge, little damage was 
noticeable. An old woodshed was thrown down (at 21, map No. 22), and about a mile 
farther on the top was broken from a large redwood tree about 75 or 100 feet from the 
ground (at 22, map No. 22). 
Following the trail from King’s Mountain House down Purisima Creek, a large slide on 
the northeast side of the creek had filled the road to a width of about 100 feet (at 23, 
map No. 22). The buildings at Hatch’s Mill, just below (24, map No. 22) were not dam- 
aged, but a little farther down several cracks were found, one 8 inches wide and running 
S. 23° E. On the northeast side of the creek, just below Borden’s Mill, a big slide had 
dammed the creek to a depth of 25 or 30 feet (at 25, map No. 22). The slide was between 
0.25 and 0.5 mile long. The buildings at the mill showed no damage, but a bridge just 
above the mill was crusht by a slide from the south side of the creek. 
Bear Creek (H. P. Gage). — Between Redwood City and Woodside, all of the public 
water-tanks were thrown down or had to be rebuilt. On the Bear Creek road, southwest 
of Woodside, there were many cracks caused by landslips down steep banks. The tops 
of 2 partly decayed trees, one a redwood and the other a spruce, had been broken off 
where the diameter was 2 feet. Near where the first trail branches to the right from 
this road, an old oven built of clay and stone, 4 feet high, was cracked, and an old barn 
was badly damaged. At the point where the road itself becomes a trail there is a log 
cabin, probably used as a summer camp. This cabin was locked and had apparently 
remained undisturbed since the earthquake. The floor is about 6 feet above the level of 
the ground. Table, benches, chairs, and all the bottles and utensils, except a coffee pot, 
were overturned. The table was solidly built and measured 4 by 8 feet. About a mile 
east of this cabin, at the end of another trail, was a 1-story frame house; a bed on the 
_ first floor was moved by the shock 8 feet to the middle of the room, tables and chairs 
were displaced, and dishes were broken. A house and dairy between this place and the 
road were moved on their foundations, and water was spilt out of pails from northeast to 
southwest. Tops of spruce trees were broken by the shock. Four miles farther south- 
west, along the trail toward the San Gregorio road, people reported that all the stoves 
on the first floor of their houses were overturned during the earthquake, with the ex- 
ception of a kitchen range which was twisted around 6 inches. Their dishes were also 
broken. Just south of the junction of this trail with the San Gregorio road, a 2-story 
house had been shifted on its underpinning and some plaster was broken. A water- 
tank 20 feet high fell at this point. 
Half Moon Bay, Purisima and San Gregorio (S. Taber). — Following the road along 
Pilarcitos Creek toward Half Moon Bay, many cracks and slides were found on the ocean 
side of the ridge, but few on the east side. All of these seemed due to slipping of the earth. 
At one place there had been such a large slide that big blocks of sandstone had fallen 
down into the road. Here and there along the road big cracks had opened, parallel with 
the road and the creek where the slope is very steep, and promising to make the road 
impassable by landslides, should a heavy rain come. 

Tra. Lane adds: ‘‘ While I was there, however, we had a slight shock and I noticed neither blast 
nor noise.”
