cover glass, rather than at the ends. A servicable and convenient 

 cabinet can be made by removing the drawers of an empty spool- 

 case and making a door for the front. The case can then be filled 

 with drawers suitable for holding the slides. To make these cut a 

 board, one-half inch thick and as wide as the case is deep, into 

 lengths one inch shorter than the width of the case. With the aid 

 of a buzz-saw and chisel, the boards can be made so that a section 

 of it will appear as the figure :

The grooves are to be cut across the grain of the wood. Cut 

 thin strips and glue them in position in the grooves 1 and 2. The 

 distance between these points should be 3 in. The slides rest 

 on the surfaces 3 and 4, and are separated by little partitions, about 

 1 in. apart, glued into a groove made across the board with the 

 saw before the partitions 5, 5 ' were placed in position. The little 

 partitions must necessarily be short, about 2 c.m. long in order 

 that they may not come in contact with the pieces 5 and 5 ' . To 

 remove the slide from the drawer, it is only necessary to press 

 down on one end when the other will be raised and can readily be 

 grasped. 



Such a cabinet can be easily made by a carpenter in a few 

 days. Much of the work can be done by machinery. The original 

 cost of the spool case should not be over $3.00. Double spaces can 

 be left in the drawers for the large sizes of slides and appartments 

 arranged in any desired way. A piece ^ inch thick fastened to the 

 end of the drawer will prevent its warping and at the same time 

 serve for a groove on which the drawer can slide. 



The number of the first and last slide in each drawer can be 

 fastened on a strip, to the front surface.
