It would have been less uncomfortable if the stray accounts of these things had not agreed so well. As it was, nearly all the rumors had several points in common; averring that the creatures were a sort of huge, light-red crab with many pairs of legs and with two great batlike wings in the middle of the back. They sometimes walked on all their legs, and sometimes on the hindmost pair only, using the others to convey large objects of indeterminate nature. On one occasion they were spied in considerable numbers, a detachment of them wading along a shallow woodland watercourse three abreast in evidently disciplined formation. Once a specimen was seen flying—launching itself from the top of a bald, lonely hill at night and vanishing in the sky after its great flapping wings had been silhouetted an instant against the full moon.
