400 KANSAS CITY REVIEW OF SCIENCE. 
time to cut out the telegraph instrument, before blinding flashes of fire came into 
both rooms from the lightning arrestor and stoves. At 7 P. M. a bolt struck 
close to the north window, and at the same time a heavy discharge took place 
through the lightning arrestor, which made me, for a moment, believe that the 
building itself had been struck and was on fire. A cloud of smoke filled the em- 
brasure of the north window, which was afterwards found to have resulted from 
the melting of the rubber insulator on the office wires. 
The lightning arrestor was badly burned, and the line did not work that 
night ; very likely the wire has been burnt outside. 
June I. — Line worked poorly. 
June 5. — Heard Boutelle (operator on the trail) call base and summit, appar- 
ently from some point of the trail, but could not break. 
June 6. — Line worked so poorly that I could not raise base at night. 
June 10. — Line open; apparently no break. 
June 18. — Much lightning passed through the arrestor, although I had the 
line wire connected outside with the ground wire. 
July I. — Heavy thunder-storm and sleet in the forenoon. Visitors caught 
in the storm said that they all experienced peculiar burning sensations on face 
and hands, and heard hissing sounds proceeding from their hair and whiskers. 
July 9. — Heavy thunder-storm SW., from 3:30 P. M. to 4:15 P. M.; heavy 
sparks through lightning arrestor. 
July 14. — Thunder-storm. I received a very painful shock while working 
over the line, my fingers accidentally touching the metal of the key. 
July 16. — Heavy thunder-storm. Sharp flashes and reports came through 
lightning arrestor to the terror of several lady visitors. Outside, the electric effects 
were still more startling. The strange crackling of the hail mentioned before, 
was again heard, and at the same time my whiskers became strongly electrified 
and repellent, and gave quite audible hissing sounds. In spite of the cap I wore, 
my scalp appeared to be pricked with hundreds of red-hot needles, and a burnir>g 
sensation was felt on face and hands. Several of the visitors, outside, experi- 
enced the same, and a large dog out doors became terrified and made for the 
door with a pitiful howl. 
July 19. — Lightning struck the wire, and for a moment the wire resembled a 
rope of fire and vibrated violently for some minutes after the discharge. No 
damage. Frequent loud discharges took place along the ground wire, between 
it and the rocks on which it rests. Hair and beard of any one out doors were 
electrified by each discharge. 
July 21. — Heavy discharges through the lightning arrestor, and although I 
had opened the key, the lightning jumped the space and worked the relay until I 
took all the wires off. 
July 22. — Received heavy shock while attempting to send a message. 
August 13. — Visitors became electrified. 
August 17. — Continuous ground currents through the lightning arrestor. 
August 22. — Visitors electrified.
