melted and the copper added subse-
quently.

from the ground or from excess of mois-
turc in the air, near the earth, coming
In contact with vegetable or other sub

ture, and is due to saturation of the mir
by cooling of both air and metal by noe
turnal radiation.
A recent improvement in arc-light
pencils consists of II wire cloth contain
ing no carbon, butts coated with chro-
mate of any kind. These chromatcs arc
non-conducting, but the metal cloth
starts the arc and the intense heat re-
duces the chromate to a chromate of the
metal used. These pencils burn at the
rate of one-eighth of an inch an hour
when the current is properly controlled.
