[[underline]] Rogers Ranch [[/underline]]

[[underline]] Nov. 12 [[/underline]] Only about half of the microtus fed Barium Carbonate were dead in the morning and these were partly eaten & may have been killed by the others. Later in the day ^[[insertion]] 10 A.M. [[/insertion]] a freshly killed mouse was evicerated & filled with barium carbonate & put in a can with 3 live ones. He was promptly eaten and a large part of the [[strikethrough]] bar [[/strikethrough]] poison taken but at 5 P.M. the 3 live mice showed no symptoms of discomfort. Barium seems worthless.

At the same time another was well filled with arsenic & put in with 3 live Microtus and in 2 hours 2 of the three were dead, the other was dead in morning.

Others were put in cans and fed apple, potatoe, cabbage, [[strikethrough]] & [[/strikethrough]] onion & beefsteak with dry arsenic scattered over them. The apple was quickly eaten as in that can the mice were hungry & had little to eat all night. In 2 hours one was dead & in 5 hours 4 more. [[strikethrough]] Cont [[/strikethrough]] Considerable of the potato was eaten but only one of the mice died before dark.

The cabbage was not eaten for some time, but by 5 oclock 2 of the mice had died and others were affected.
