THE CAMERA

the workrooms, and when yon come out 

 of those rooms, "fancy price" has fol- 

 lowed its twin, the "little hetter," to its 

 grave — buried with the things of the 

 past that you would like to forget. 



When you have seen the careful 

 selecting of the glass ; the long, tedious 

 grinding ; the careful polishing ; the 

 delicate adjustments ; the mathemati- 

 cal centering of the lenses, and, finally, 

 the rejection of every one that is not 

 absolutely perfect, you will exclaim : 

 "The marvel is that so much can be 

 sold at so low a price." 



Consider too what a marvel of work- 

 manship is an anastigmat lens. Six 

 pieces of glass — twelve surfaces ground 

 to perfect curves, and then all six accu- 

 rately centered to one another, so that 

 light is truly turned in its course — sev- 

 eral prisms yet without prismatic color- 

 ing. Lines are brought from the ex- 

 tremes in every direction from the cen- 

 ter — up, down, right, left, everywhere, 

 and all treated by the lens with equal 

 fairness. The objects whose light 

 comes through the center of the lens, or 

 near it, have no better treatment than 

 those at the extreme margin. It is a 

 tiny bit of exquisite workmanship to be 

 held in tender appreciation — to be loved
