 in place, and to protect the mounting from possible injury.

may be used on the edges to secure the pieces 

 before wrapping for mailing. If one slide is to 

 be sent the strips may be gummed lengthwise on 

 the edges. If centres are used for more slides 

 the strips may be used to pass around on to top 

 and bottom. The slight shrinking of the moistened paper in drying 

 pinches the slide sufficiently to hold it securely. 



A. C. Cole uses the boxes shown in fig. 79. They consist of a 

 piece of wood 3^ in. X If in. and 1/2 in. thick in which a coarse saw- 

 cut has been made nearly through it as shown in the figure. The 

 slide is placed in the groove thus formed with a little cotton wool 

 and the open side is filled up with a strip of wood about 3/16 in.
