 Storing Negatives. As the number of our 

 negatives increases, the necessity of storing 

 them in some systematic manner which will 

 keep them in safety and at the same time 

 facilitate the prompt finding of any one as 

 needed, becomes more and more apparent, if 

 we have not started to do so at the outset of 

 our work. It is, therefore, wise to begin this 

 important item with the very first negative 

 made. Two methods are suggested, both of 

 which have been found good and practical. 

 In the first, the negatives are to be placed in
