On the outskirts of Derby in Western Australia you’ll find Myall’s bore. It feeds the Southern Hemisphere’s longest water trough. At 120 metres in length, 500 cattle could drink from this trough at the same time. One can just imagine the sight, smell and sound. In the droving days cattle were rested here overnight. The next day they would be moved a few kilometres closer to town to the Dinner Tree, a large boab, where they would be rested in the midday sun before being herded across the endless mudflats to the waiting ship at Derby wharf.
