Read it through once

There must have been a sufficiency of moas in the old forgotten days when his breed walked the earth. His bones are found in vast masses, all crammed together in huge graves. They are not in caves, but in the ground. Nobody knows how they happened to get concentrated there. Mind, they are bones, not fossils. This means that the moa has not been extinct very long. Still, this is the only New Zealand creature which has no mention in that otherwise comprehensive literature, the native legends. This is a significant detail, and is good circumstantial evidence that the moa has been extinct 500 years, since the Maori has himself—by tradition—been in New Zealand since the end of the fifteenth century. He came from an unknown land—the first Maori did—then sailed back in his canoe and brought his tribe, and they removed the aboriginal peoples into the sea and into the ground and took the land. That is the tradition. That that first Maori could come, is understandable, for anybody can come to a place when he isn't trying to; but how that discoverer found his way back home again without a compass is his secret, and he died with it in him. His language indicates that he came from Polynesia. He told where he came from, but he couldn't spell well, so one can't find the place on the map, because people who could spell better than he could, spelt the resemblance all out of it when they made the map. However, it is better to have a map that is spelt right than one that has information in it.
