these pieces have their upper corners 

 rounded and the bottom part cut out to 

 form a projection that gives it a pleasing 

 appearance. These shapes are drawn as 

 designated in Fig. 6. They are then fast- 

 ened to the base with screws, Fig. 7. 



The brackets are shaped as shown in 

 Fig. 8. These are fastened to the underside 

 of the base with screws, as are also the 

 back uprights. It is best to give the sur- 

 face of all joints a good coat of glue before 

 turning in the screws. It is necessary to 

 bore a hole before driving a screw in 

 cabinet work. This may take a little time 

 but it saves a great deal of trouble in the 

 end. 



The central division may also be used 

 as a place for a small clock. — H. Adlon. 



Paper Clips with a Stick Used for 

 Paper File 



THERE is now on the market a simple 

 spring steel clip that renders it a very 

 simple matter to contrive a satisfactory 

 file for newspapers, blueprints or drav/ings. 

 Three clips are necessary, and these are at- 



tached at the center and at each end of a 

 slender stick of the required length. The 

 latter should preferably be of oak about 

 3/16 in. by I in. Each 

 clip is held in place 

 by means of two 

 small wire nails driv- 

 en in through holes 

 punched near the 

 ends of the clips, all 

 as indicated in the 

 accompanying illus- 

 tration. When not 

 in use, the small 

 handles may be 

 pushed flat against 

 the sides, leaving one 

 remaining up in the 

 center so that the file may be hung up. 

 The sheets may be filed on one or both 

 sides of the center strip. — John D. Adams.

Goggles to Be Used When Making 

 Chemical Experiments 



A PAIR of motor-goggles with windows 

 of mica rather than glass, afford 

 valuable protection to the eyes when 

 experimenting in a chemical laboratory. 

 A pair should be kept handy for use when 

 operating with flasks and tubes of boiling 

 liquids that are apt to decrepitate and 

 spurt. The most comfortable to wear are 

 those with large windows having an edging 

 of chenille or velvet. — H. J. Gray.
