Read it through once

Those sad gums stood up out of the dry white clay, pictures of patience and resignation. It is a tree that can get along without water; still it is fond of it—ravenously so. It is a very intelligent tree and will detect the presence of hidden water at a distance of fifty feet, and send out slender long root-fibres to prospect it. They will find it; and will also get at it even through a cement wall six inches thick. Once a cement water-pipe under ground at Stawell began to gradually reduce its output, and finally ceased altogether to deliver water. Upon examining into the matter it was found stopped up, wadded compactly with a mass of root-fibres, delicate and hair-like. How this stuff had gotten into the pipe was a puzzle for some little time; finally it was found that it had crept in through a crack that was almost invisible to the eye. A gum tree forty feet away had tapped the pipe and was drinking the water.
