During the summer months in the great valleys and canyons of the eastern and southern portions of the State thunderstorms frequently occur during the afternoon and evening hours. John Muir, writing in the Atlantic Monthly for September, 1901, on the Big Trees, makes the following statement: "Most of the Sierra trees die of disease. Thus the magnificent silver firs are devoured by fungi, and comparatively few of them live to see their three hundredth birth year. But nothing hurts the Big Tree. I never saw one that was sick or showed the slightest sign of decay. It lives on through indefinite thousands of years, until burned, blown down, undermined, or shattered by some tremendous lightning stroke. No ordinary bolt ever seriously hurts Sequoia. In all my walks I have seen only one that was thus killed outright.

"Lightning, though rare in California lowlands, is common on the Sierra. Almost every day in June and July small thunderstorms refresh the main forest belt. Clouds like snowy mountains of marvelous beauty grow rapidly in the calm sky about midday and cast cooling shadows

and showers that seldom last more than an hour.
or kill a good many trees. I have seen silver firs 200 feet high split into long peeled rails and
slivers down to the roots, leaving not even a stump, the rails radiating like the spokes of a wheel
from a hole in the ground where the tree stood. But the Sequoia, instead of being split and
slivered, usually has 40 or 50 feet of its brash, knotty top smashed off in short chunks about the
size of cord wood, the beautiful rosy-red ruins covering the ground in a circle 100 feet wide or


"I never saw any that had been cut down to the ground, or even to below the branches, except one in the Stanislaus Grove, about 12 feet in diameter, the greater part of which was smashed to fragments, leaving only a leafless stump about 75 feet high. It is a curious fact that all the very old Sequoia nave lost their heads by lightning. All things come to him who waits,' but of all living things Sequoia is perhaps the only one able to wait long enough to make sure of being struck by lightning. Thousands of years it stands ready and waiting, offering its head to every passing cloud as if inviting its fate, praying for heaven's fire as a blessing, and when at last the old head is off another of the same shape immediately begins to grow on."

During November and December there were few, if any, thunderstorms in California.
The following notes relative to the character of the storms may be of interest:

On January 26, 1896, the plant of the Haywoods Electric Light Company was struck by lightning. The electrician, Mr. J. Putnam, is reported as saying:

I was not more than 20 feet away from the dynamo when the crash came, and it seemed as if the lightning filled the whole building. The flames shot out from the dynamo about 8 feet, and the wires, magnets, and mica were thrown all over the place. I instantly ran to the switchboard and disconnected the wires, and there was no more

light that night. The accident was a very simple one, and one that will be guarded against in future. The lightning was conducted to the machine by one of the wires, and of course the dynamo was instantly overcharged and burnt. * * There is one hole and no trace of the missing metal. The wires that surrounded the magnets were so highly charged that they flew in all directions, and when the mica was free it fell around in showers. It will take several days to fix the wrecked machine. If I had been oiling that dynamo when the lightning struck I would have been charred to a cinder as rapidly as that piece of iron was burned.


At Folsom, on the 24th of April, lightning struck the lines of the Electric Light and Power Company five times, and the machines went out of step at each stroke. The lightning arresters were burned and discolored. On April 9, at Ontario, two strokes of lightning entered the electric power house. Wires were burned and a coat belonging to one of the employees set on fire.

The first stroke, it is stated, came from overhead, while the second struck the wires miles away and came in when the sky was clear overhead. Lightning conductors were under the floor, but had not been connected, as it was thought there would be no use for them. After the first stroke they were connected. Notwithstanding, the second stroke did more damage in the power house than the former, showing that it was much the heavier charge.

The Fresno Republican of October 17 reports that

A heavy thunderstorm in the hills caused a shutting down last evening of the entire electric plant of the San Joaquin Electric Company for twenty minutes. The lightning passing over the lightning arresters caused the points to become welded together, forming a short circuit across the two lines. Occurring at a time when the city was in darkness the delay in repairing was greater than it would have been during the day. No great damage was done to the machinery.

In the city of San Francisco houses and barns have been struck and some damage done. A large cypress tree on the southeast corner of Broderick and Green streets was riven from branch. to root. A very large branch was torn off and thrown some little distance. On August 19, 1896, the signal-flag pole at Point Lobos was struck by lightning and badly damaged. The pole was 60 feet high, and the upper 20 feet were so torn that a new pole was necessary. Large splinters of wood were thrown over 150 feet away. Lights were burned out at the terminus of the Sutro Electric Railroad, and other damage done in the vicinity.

On November 7, 1900, four distinct flashes of lightning, accompanied by loud thunder, were recorded at the Weather Bureau office at San Francisco. The first flash was at 10.15 a. m. and the others at 10.27, 10.30, and 10.42 a. m. The average interval between the flash and the thunder was about six seconds. On December 14, 1900, during a sharp thunderstorm a flash of lightning struck the relief gasometer at Bay and Buchanan streets, containing 260,000 cubic feet of gas. The tank was demolished and the gas ignited. The flame was carried by the gale a distance of 250 feet, and the roar could be heard above the noise of the storm. The officials of the gas company estimated the loss at $6,000.

On October 3, 1901, at Houghton ranch, near Thomas Creek, about 12 miles west of Corning, Cal., during a heavy thunderstorm Coutea Jobe, aged 20 years, was struck by a flash of lightning and killed.

The light-house on the Southeast Farallon Island was once struck and a small amount of damage resulted.
