MAMMALS OF AMERICA 



are so self-evident that every one sees the meaning, and thus upon observation depends 

 the extent of the individual's study. Observation, reading, and scientific method are the 

 student's trinity. Some Mammals lend themselves readily to observation, as, for example, 

 the Squirrels and Hares; while others require more skill in pursuit, but yet may be watched 

 if moderate pains be taken, the Pocket Gophers and Woodchucks coming into this categorA*. 

 Still others, although not particularly rare, are difficult to observe, and experienced students 

 live a lifetime without adding much first-hand knowledge to their store; such common 

 Mammals as Bats and Moles having little-known life histories to this day. Lastly, the 

 method gained by the study of a systematic account of Mammals, or any other class of animal 

 life, will never be regretted in any pursuit, or at any time, for, cloaked in an entertaining 

 garb, the basic principles that underlie all sciences have been introduced to the student, 

 and as a consequence he should be the gainer in accuracy of observation, interpretation, 

 and well-rounded knowledge.
