THE GUIDE TO NATURE. 



YAID 

 THE LENS 



WITH THE POCKET MAGNIFIER. 



Some years ago Agassiz in the ex- 

 pression "Study Nature, not Books," 

 pointed a way to a fuller appreciation of 

 this old sphere upon which we live. But 

 we have not followed the suggestion as 

 closely as we should, and most of us 

 know a very, very little about what is 

 constantly going on around us in the ani- 

 mal and plant world. 



It is true that most of the actors on 

 the stage are too small to be seen with- 

 out the aid of a lens, but this need not 

 prevent us from enjoying the beauty and 

 novelty of these small bits of life, for 



there a r e 

 many excel- 

 lent pocket 

 magnifiers or 

 hand lenses 

 (such as 

 those made 

 by the Bausch & Lomb Optical Co., of 

 Rochester, N. Y.) which are within the 

 reach of all. 



But, you may ask, what is to be seen ? 

 Simply multitudes ! With a pocket mag-

 lens. Price S3 5°) 



(The Hastings Triplet, one of the 

 best magnifiers. Price $7.5o) 



nifier as an out-of-door companion every 

 stagnant pool, every decaying piece of 

 wood becomes full of interest, and our 

 walks cannot lead us into paths that 

 are devoid of scenes worthy of our 

 attention. Ev- 

 ery stone in the 

 \v< iodland, when 

 turned over, 

 opens a door in- 

 to a new and 

 different land 

 where the many legged inhabitants go 

 scurrying to and fro performing their 

 part in the division of labor just as in- 

 dividuals in a well organized community 

 of men do. Indeed many examples of 

 activity and the strenuous life may be 

 found which are well worth following! 

 One becomes absorbed in the study of 



sensitive 

 antennae, 

 the absurd- 

 ly formed 

 m o u t h 

 parts, the
