Men Like Gods by H.G. Wells

Cedar and Serpentine remained with the Earthlings upon Quarantine Crag until late in the afternoon. They helped to prepare a supper and set it out in the courtyard of the castle. They departed with a promise to return on the morrow, and the Earthlings watched them and their accompanying aeroplanes soar up into the sky.

Mr. Barnstaple was surprised to find himself distressed at their going. He had a feeling that mischief was brewing amongst his companions and that the withdrawal of these Utopians removed a check upon this mischief. He had helped Lady Stella in the preparation of an omelette; he had to carry back a dish and a frying-pan to the kitchen after it was served, so that he was the last to seat himself at the supper-table. He found the mischief he dreaded well afoot.
