" I do not know, boys ; but I should think 

 his discovery of the shield would make him 

 an attentive observer, if he was riot so before." 



" Now, Uncle Philip, will you tell us of the 

 tweezers ?" 



"Very willingly, boys. This instrument 

 or tool belongs to the moths which you see 

 flying about at times. The tails are covered 

 with a down, which grows in the form of a 

 thick brush or tuft, and has a shining silky 

 gloss, different in colour from the short hair 

 upon the rest of the body. The moth pulls 

 off this hair to cover its eggs, and the twee- 

 zers are used for that purpose. Here is a pic- 

 ture of the moths."
