I figured then to dig out said mole from this short section of dead end burrow. But this wasn't necessary. The commotion causes the mole to turn around and start his head long retreat only to come to the opened burrow where it can be caught by hand. Since this seems to work I now plan on using the lights now. In addition to the fact that the traps are still not successful. However the light is hard to see in daytime so have now devised a contraption that drops a flag in daytime in addition to lighting a light at night.
Put Schamm made slides of one tube of #13654 which was very large but no sign of bumps (embryos). It proved to not be pregnant.
Slides of #13655 of an ovary showed it was about ready to ovulate but hasn't had yet. These tubes were enlarged but not as large as 13654
