406 KANSAS CITY REVIEW OF SCIENCE, 
three quarters of an hour the new one was working, but the electricity was still 
very intense. 
Assistant Sweeny was nearly deaf for some time afterwards. One piece of 
the wire was thrown with such force that when it struck the barometer, three feet 
distant, it was wound around it without, however, doing damage to the ba- 
rometer. 
.October 13. — Atmospheric electricity on wires to night. 
November 19. — This forenoon a boiler lid was noticed to become charged 
with electricity, and would give off an unpleasant shock. 
1880, February 9. — Clear weather, rising barometer and high winds. Tele- 
graph line in bad condition and working poorly. Assistants Davis and Jones 
called repeatedly by Assistant Blake, but he was unable to raise the base station. 
Blake remained at the key for more than an hour adjusting and calling, but did 
not succeed in getting off the signals. 
February 10. — Cloudy. Light snow during the day. Line working all 
right but it was impossible to break the lower station. 
April 25. — Cloudy weather. Line working badly at 9:07 P. M. Signals 
sent with difficulty. 
May 19. — Atmospheric electricity in the wire all day. 
June 20, — From 6:50 to 8:35 P. M. very small discharges of atmospheric elec. 
tricity. Line working very badly. 
June 23. — Severalhght thunderstorms passed over and north of the Peak 
during the afternoon. At 7:10 P. M. a heavy snow storm set in accompanied 
by terrific flashes of lightning and heavy rolling thunder. Telegraph communi- 
cation interrupted. 
July 3. — Heavy electricity on the wire at midnight observation. No report 
sent, as each flash of lightning threw the instrument out of adjustment. 
July 18. — Hail at 5 P. M. lasted until 7:15 P. M. accompanied by heavy 
shocks of electricity. 
July 20. — Hail accompanied by terrific discharges. Atmospheric electricity 
quite prevalent during the evening and line working very poorly in consequence. 
July 21. — P. M. Hail and heavy flashes of lightning which played around 
the lightning arrestor and exploded with great force. 
July 23. — From 1:35 P* ^' to 5:40 ?• M- heavy rainstorm. Intense ground 
currents of electricity quite frequent during the prevalence of the storm. 
August 3. — At 11:40 A. M. hailand terrific flashes of lightning which exploded 
with great force on the lightning arrestor and interfered with the working of the 
telegraph line. 
September 10. — Hail from 1:40 P. M. to 2:50 P. M., accompanied by ter- 
rific discharges of electricity which for a time suspended all communication 
between base and summit and made telegraphing a very dangerous experiment. 
October 26. — At 12:50 P. M. a heavy thunderstorm with light snow and 
sleet. Lightning passed constantly through the lightning arrestor with loud 
reports.
