Suddenly an eleven-inch shell dropped straight in the centre of the pool and exploded on the concrete bottom which underlay the mud. Half the pool went up in the colossal eruption of blown flame and steam and smoke. Even here on his perch the eagle found himself spattered and drenched. When the shrunken surface of the pool had closed again over the awful vortex, and the smoke had drifted off to join itself to the dark cloud which hung over the city, the little flock of ducks and coot was nowhere to be seen. It simply was not. But a bleeding fragment of flesh, with some purple-and-chestnut feathers clinging to it, lay upon the bottom of the cage. This morsel caught the eagle's eye. He had been forgotten for the past two days--the old one-legged keeper of the cages having vanished--and he was ravenous with hunger. He hopped down briskly to the floor, grabbed the morsel, and gulped it. Then he looked around hopefully for more. There were no more such opportune tit-bits within the cage, but just outside he saw the half of a big carp, which had been torn in twain by a caprice of the explosion and tossed up here upon the grass. This was just such a morsel as he was craving. He thrust one great talon out between the bars and clutched at the prize. But it was beyond his reach. Disappointed, he tried the other claw, balancing himself on one leg with widespread wings. Stretch and struggle as he would, it was all in vain. The fish lay too far off. Then he tried reaching through the bars with his head. He elongated his neck till he almost thought he was a heron, and till his great beak was snapping hungrily within an inch or two of the prize. But not a hair's-breadth closer could he get. At last, in a cold fury, he gave it up, and drew back, and shook himself to rearrange the much dishevelled feathers of his neck.
