 is not difficult, provided the hinge is 

 neither too tight nor too loose. When 

 the glass has been placed as it should

 in poor lights. If it be desirable to

 other guides and supports the pole. 

 Whenever I take the looking-glass 

 with me on distant excursions, I 

 carry it detached, in a leather case,

 thought it worth calling to the 

 attention of the readers of Bird- 

 Lore. Perhaps it could be im- 

 proved upon, but at least it has 

 served my purpose well.
