"Laang (stone) is highly utilised to sustain booboop narrkwarren-in (your family). Dirrandil (seeds) and bulbs/tubers are ground to create ngurrung (bread) to be baked in an earth oven. Wilam (bark/shelter) is also ground down to create medicine, or to create a wilam (shelter/bark). Ochre is also crushed on the grinding laang and painted on your marram (body) to form part of important ceremonies, or used to decorate implements, weapons and tools. These grinding laangs can still be found preserved all over the country.
Your garrginj (axe) is also ground down and used to fight your enemy, create notches to climb in trees to capture game, such as walert (possum), or to cut out a gayaam (shield) or gurrong (canoe). The highly prized garrginj is buried when its owner has passed. Today evidence of the importance of the garrginj can be found at Mt William greenstone quarry near Lancefield in Victoria.
Both the grinding laang and the garrginj are still very highly prized and utilised today. As is ochre, which is used in ceremonies still".
