RECENT LITERATURE. 
Merriam’s Biological Survey of Mount Shasta.!— “All high moun- 
tains,” as Dr. Merriam remarks in his ‘Introduction,’ “ particularly those 
that stand alone, are likely to throw light on the problems of geographic 
distribution, and are worthy of careful study. Shasta, not only because 
of its great altitude [14,500 feet], but even more because of its intermedi- 
ate position between the Sierra and the Cascades, promised an instructive 
lesson, and was, therefore, chosen as a base station for part of the field 
work of 1898.” 
An introduction of eight pages contains an itinerary of the field work, 
the personnel of the party, a notice of previous publications on Mount 
Shasta, and a list of the new species described in the report—5 plants 
and 8 mammals. The subtitles indicate the general character of the 
report, as follows: ‘General Features of Shasta’ (pp. 17-30); ‘The For- 
ests of Shasta’ (pp. 30-46); ‘ Forest Fires’ (pp. 46, 47); ‘Slope Exposure’ 
(pp. 47-52); ‘Life Zones of Shasta’ (pp. 52-68); ‘The Boreal Fauna and 
Flora of Shasta contrasted with corresponding Faunas and Floras of the 
Sierra and the Cascades’ (pp. 69-82); ‘Efficiency of Klamath Gap as a 
barrier to boreal species compared with that of Pitt River and Feather 
River Gaps collectively’ (pp. 83, 84); ‘Sources of the Boreal Faunas of
