BIRD-WORK FOR INDOORS 237 



the light. If the lantern-slides are kept in boxes or 

 drawers, they will not fade perceptibly for a long 

 time. 



It is well to have albums of prints of all pictures 

 thought worth saving and keep them up to date by 

 printing, each winter at least, the series of the pre- 

 vious season. Should anything happen to the nega- 

 tives, as by a fire, the prints could be copied, and 

 one would not lose the whole accumulation of years. 

 Should a valuable negative be lost or broken, it could 

 then be replaced. In the case of specially valued 

 pictures, it is very gratifying to have them framed 

 on the walls, enlarged or colored if desired. 



From the above hints it can be seen what a de- 

 lightful program of fascinating indoor work may 

 be enjoyed by the bird-enthusiast. This will do much 

 to make the periods of disagreeable weather thor- 

 oughly enjoyable and keep the mind that has the in- 

 stincts of the naturalist satisfied and content till the 

 spring returns, the birds sing, and again we can be 

 much of the time outdoors.
