[[underline]] Oct. 9 [[/underline]]. In the three arsenic tests on wheat, barley, and sugar beets the mice were all dead in the cans this morning but one. In the two tests of cyanide on wheat & sugar beets none of the mice were dead except a few that had probably been hurt & were eaten up by the others. So I mined a peck of [[insertion]] ^ wet [[/insertion]] wheat & peck of wet cracked barley with half a pound each of dry arsenic and cut up a quart of sugar beet cubes [[image - of cube]] and rolled in arsenic & put out in the field. The wheat & barley each covered about an acre, distributed in burrows & runways and it took two of us half an hour to put out each kind. The result remains to be seen, and two nights should be allowed for definite results.

My baggage came & I set a few traps for gophers and took some photographs.

Carried out the dead Microtus & had them plowed under & caught a fresh lot of live ones. With a tin can in one hand & gloves on I followed the plow for 35 minutes & caught alive 127 Microtus.
