Book excerpt: Excerpt from The Lead-Cable Borer, or "Short-Circuit Beetle" In California Cable trouble due to insect boring seems to approach most closely to regularity of occurrence in California, where the districts affected extend along the coast from San Diego to some distance north of San Francisco, although trouble has been reported at points as far inland as Sacramento and Marysville.

Holes.--To determine if the beetles are attracted to holes already started in the cable by other means, a section of a cable was punctured and partially punctured by a number of holes, some shallow and some nearly through the sheath, and placed in a cage. Fortyfive beetles were introduced into the cage on two different occasions. Six males were found in the holes at various times but no females. Colors.--To determine the attractive effect of colors on the beetles, sections of dead cable and sections of wood were painted in alternating rings of red, yellow, and green and placed in the large experimental cage. Over 1,500 beetles had a chance to attack these, but none did. Fermentation Experiments. Alcohol.--To determine the attractive effect of alcohol on the beetles the following experiments were carried on in addition to those mentioned under "Aerial cage" and "Battery cage." Twenty glass vials 11 millimeters by 60 millimeters were placed in a cage. Ten of these were empty and 10 contained grain alcohol. All were closed with cork stoppers. They were placed in the cage in two rows, empty alternating with alcohol-filled, and cork end alternating with glass bottom. Forty-five beetles were placed in the cage on two different occasions. One cork of an alcohol-filled vial was attacked and bored several times and two others slightly bored. 2047--22 5 All of these attacks were at the point of contact of the glass with the cork. One cork of an empty vial showed a slight attack well above the glass. In another experiment two 30 by 100 millimeter vial corks were soaked in...
