Lester F. Ward. (Carboniferous Glaciation.) 



Public Opinion, vil, Juue 15, 1889, p. 221. 



A notice of an article by Mr. C. I). "White entitled: Carboniferous Glaciation in the Southern 



and Eastern Hemispheres, with some notes on the Glossopteria flora. 

 Attention is specially called to the importance of the view expressed in Mr. White's article 

 that the Glossopteria flora, though MesozoiC in aspect, is probably Permian in ago and is 

 the true ancestor of the widespread Kinetic and Jurassic floras of the northern hemisphere) 

 and was developed in reponse to the gradual lowering of the temperature at the period, 

 replacing the true Carboniferous types which could not survive the change, and subse- 

 quently migrating northward on the return of the tropical climate to reappear at many 

 points as a distinctive Mesozoic flora.

The purpo. e of this book appears to be to enlighten the public, especially the farming commu- 

 nities in Pennsylvania, in regard to the birds that are to be found in the State, to awaken 

 a desire for their protection upon economic grounds, and to stir up an interest in natural 

 history among the people. 

 "The Report was printed by direction of the legislature of Pennsylvania for gratuitous dis- 

 tribution in the State, and the demand so far exceeded the supply that the edition of 6,000 

 copies was quickly exhausted, and, we are very glad to learn, the publication of a second 

 edition of 10,000 copies, revised and enlarged, has been ordered. When this book has 

 found its way into schools and farmhouses throughout Pennsylvania the profit to the birds, 

 to the fanners, and to Ornithology that ought to result is incalculable. If other States 

 would follow such a good example, it would be an important step toward lifting the cloud 

 of ignorance that hangs over the rural mind upon matters of natural history."
