New Zealand - Kauri Gum - Kauri gum in its rough state being put through an oil-driven washing machine - This operation saves time and labour, besides preventing waste. - 27/7/1922 - Unknown Photographer - Originally published in "The Auckland Weekly News" #335963 - Kauri gum is a fossilised resin detracted from kauri trees. - It is made into crafts such as jewellery. - Kauri gum formed when resin from kauri trees leaked out through fractures or cracks in the bark, hardening with the exposure to air. - Lumps commonly fell to the ground and became covered with soil and forest litter, eventually fossilising. - Other lumps formed as branches forked or trees were damaged, which released the resin.
