Some savant of the saloons has compiled the following catalogue of alcoholic passwords: New Jersey—“Well, here we go!” New York—“My regards.” California—“How!” Indiana—“Here’s to us.”

—“Here we go.” Mexico—“A la salud de U.” (Your health.) Illinois—“Another nail in the coffin.” Ohio—“I hope I see you well, sir.” Kentucky—“Time.” Maine—“Take it sly.” Boston—“To the club.” Wisconsin—“Here’s looking at you.” Virginia—“Here’s hoping.” Pennsylvania—“Here’s to the old grudge.” North Carolina—“Here’s all the hair off your head.” Nevada—“Here we jolt.” Miscellaneous—“Boys, what’ll you have?” “Let’s go and take a ball.” “Name yer pizen.” “Gentlemen, please name your beverage.” “Gentlemen, will you join me?” “Well, how will you take it?” “Gimme some of the old stuff.” “A gin fizz, if you please.” “Whisky (if you can spare it).” “Let us go and shed a tear.” “Here’s another luck.” “Beer all the time—nothing but beer.” “Give it to me straight.” “Good-by.”
