One of the books of nature study which can be unqualifiedly praised is called •• Shells 

 &i I^and and W^ater/* by Prank Collins Baker, the curator of the Chicago Academy of Sciences. 

 It contains in limited space a report of the proceedings of a conchological club, the members 

 ®l which are boys seeking knowledge of mollusk life under the guidance of a competent 

 laacher. The first investigations are made in fresh water, where clams and water snails of 

 tSTcral sorts are found, their structure explained and the whole subject opened for diseussion. 

 Thence the teacher and pupils pass into the forest, where they make a similar study of land 

 •aails and their minute kinsfolk. After this the scene changes to the seashore and concludes 

 with studies of the cuttlefish and their allied forms. There are numerous pictures in color of 

 tka shells of these interesting animals, a glossary of technical terms used in the narrative, a 

 fnll working bibliography and a complete index. The work is fully anthentic, brought up to 

 tht present morat nt, and a m«an© ol iaf«rmatl£»n to be regarded highly. — Daily News, CAica^o,
