The Commission also continues the publications which are de- 

 voted to papers of greater length and detail. Recent issues 

 include No. 22 B, Art. 1-3, pp. 1-50, and Art. 4, pp. 51-74. The 

 last named, by K. Honda and T. Terada, is on the Geyser of 

 Atami, Japan, whose periodic eruptions exhibit some remark- 

 able features for which an explanation is offered. 



5. Field, Laboratory, and Library Manual in Physical 

 Geography • by C. T. Wright. Pp. xii and 178, with 46 figures. 

 1906 (Ginn & Co., New York and Boston). — A distinct feature 

 of this very practicable book by a High School teacher of Phys- 

 ical Geography is its three-fold division into "Library Manual", 

 "Field and Laboratory Manual" and "Note Book". The Library 

 Manual includes lists of text-books and reference books and a 

 category of special terms to which the references relate. It is 

 noteworthy that the lists of references as distinct from the lists 

 of texts includes a commendably large proportion of books 

 which emphasize the scenic phases of the subject in addition 'to 

 the strictly scientific. The scenic aspects of Physical Geography 

 are too often overlooked at the expense of interest and influence 

 in the later relations of the student. 



The second division of this manual does not rely throughout 

 upon meagre cross-section exercises on topographic maps, the 

 mainstay of more than one recent manual, but includes serious 

 exercises on evaporation and condensation in relation to rainfall, 

 winds and temperature in relation to zones of climate, the appar- 

 ent motions of the sun in relation to latitude, and geologic pro- 

 cesses as factors in the evolution of topographic forms. 



The ontographic section on plants, animals, and man, although 

 not Physical Geography, is suggestive, and is desirable inasmuch 

 as many students do not continue academic studies beyond the 

 High School and are never otherwise brought into contact with 

 this interesting aspect of Geography. i. b. 



6. Symposium on Water Supplies in Michigan. Reprinted 

 from the Eighth Annual Report of the Michigan Academy of 

 Science; by Frank Leverett, Victor C. Vaughan, G. S. Wil- 

 liams, M. O. Leighton, and Israel C. Russell. Pp. 99-136, 

 1908. — This paper includes a discussion of the geological con- 

 ditions governing the occurrence of the water supply of Michigan, 

 the pollution and purification of municipal supplies and ideals 

 concerning them. Numerous data of general interest to geolo- 

 gists are presented in compact form in the first section by Frank 

 Leverett, with reference to the chemical composition of the lake 

 waters and the water of streams, lakes and ponds, as well as that 

 from underground sources. In the last section, "Ideals concern- 

 ing Municipal Water Supplies", Prof. Russell presents some 

 interesting theoretical considerations on the whole subject of 

 water supply. i. b.
