The OED says: "tarrier, obs. or vulgar form of terrier (dog)."

I don't know what a Daisy-Etta is but I have some photographs taken at the tunneling of the intake at Parker Dam for the Los Angeles Aqueduct and then for the Diversion Tunnels at Boulder Dam. They show these big drilling platforms in which pneumatic drills are placed in cradles and the whole thing moves up to the rock face so that some number like sixteen miners are at work simultaneously drilling the blast holes. That, too, must have been a hell of a scene. I know at Boulder, the temperature in there used to get up to 110, the air was filled with dust and men collapsed from heat prostration. Some died. No wonder the IWW took hold there.
