Tip of the hat to Darian Zam who gave me the heads up that this booklet was up for auction recently at TradeMe. Here are some images from the handbook.
Warning Against Feeding or Teasing of Animals: Visitor are requested to be extremely careful what they give the various animals and birds to eat; tobacco in any form is most harmful; the Polar Bears and other special animals must not be given food of any description. Animals or Birds must not on any account be teased or irritated. Persons found wrongfully feeding or annoying exhibits will be prosecuted; since the opening of the Zoological Park several valuable exhibits have died as the result of harmful feeding by visitors.
