From Chicago “Tribune.”
“The Tribune’s agitation for a system of umpire’s gestures to indicate decisions seems to be as far-reaching as popular. Chief Zimmer has been using signs for balls and strikes and delighted New Orleans patrons. Today Collins, who officiated here, adopted the same system and used it successfully, with the result the crowd forgave him for not calling everything the local twirler pitched a “strike.” To date Hank O’Day appears to be the only opponent of the idea.
