"An unscientific account of a scientific expedition" is what Mrs. Mabel Loomis Todd happily styles the story of the Amherst Eclipse Expedition, told in _Corona_ and _Coronet_[52]--"Corona" being what the expedition went to see, and "Coronet" the vessel that took it to the observing station. Professor Todd was the astronomer of the party, and Mrs. Todd, who has published a work on astronomy, was his companion. She believes that certain aspects of the trip, covering as it did more than ten thousand miles of sailing for the party, and at least forty-five thousand miles of deep-sea voyaging for the Coronet, were worthy of narration. The astronomical purposes of the expedition, the objects it sought to obtain, the scientific bearings of the observations, and the methods, are intelligibly set forth in the introduction to the book. The rest is devoted mostly to narrative, the social aspects of the voyage, and the incidents. A short sojourn was made at the Sandwich Islands, where the more interesting objects were visited. Mrs. Todd was with Kate Field when she died there, and gives an account of her last hours. A voyage of four weeks carried the party to Yokohama, whence some of the members went to the capital and other interesting points in Japan, while the rest were preparing the observing station at Esashi, eleven hundred miles north of Yokohama--"a village on the shores of the Sea of Okotsk, among the hairy Ainu," in a region so remote that the native steamers had only recently begun to go there at all. Besides the account of the observations, descriptions are given of such Japanese experiences as life in Kioto, cormorant fishing, yachting in the Inland Sea, the tidal wave, and observations among the Ainu, with a visit on the way home to an Arizona copper mine.
