Entolai may be characterized as a " phil- 

 osophical romance," or as a life history, 

 with a religious element, described other- 

 wise by the author, A. M. Bourland, as a 

 letter to those he loves about science and 

 the ideal. Its purport may be conceived 

 from the dedication : " To those whose love 

 of Nature has so thoroughly possessed them 

 that they have been able to escape from 

 every vestige of superstition, and as a con- 

 sequence of which have embraced an un- 

 faltering faith in the loving confidence in 

 righteousness, that sustains all things, and 

 rejoices in all truth." (Van Buren, Ark. : 

 Lloyd Garrison.) 



From Earth's Center : A Polar Gateway 

 Message, is the title of a story embodying a 

 thinly disguised teaching of some of the 

 doctrines of the Edward Bellamy school, by 

 8. Byron Welcome. A country within the 

 earth, reached by means of a polar current, 

 is supposed, where the ideal prevails of the 

 conditions imagined by the dreamers of the 

 class we have referred to. 



Among recent bulletins of the United 

 States Geological Survey is a Report of Work 

 done, in the Division of Chemistry and Physics, 

 for 1890-'91, by Frank W. Clarke, which is 

 occupied mainly with analyses of minerals 

 and meteorites. Another bulletin is a Record 

 of North American Geology for 1890, by 

 Nelson H. Darton, being an alphabetical 

 author and subject bibliography of books 

 and essays in periodicals, dealing with North 

 American geology, and received by the Sur- 

 vey in 1890. Works on general geological 

 subjects, if printed in North America, are 

 also included. Samuel H. Scudder describes 

 in another bulletin, with three plates, Some 

 Insects of Special Interest from Florissant, 

 Colorado. Still another is a record of Earth- 

 quakes in California in 1890 and 1891, by 

 Edward S. Holden. It consists of an ob- 

 servation of each shock made at the Lick 



Observatory, together with brief descriptions 

 from many city and country newspapers in 

 various parts of the State.
