PREPARATION OF LANTERN SLIDES 



[Cn. VIII 



340. Summary of Chapter VIII: 



Do 



1. Use the standard size of 

 lantern slides in the country 

 where you live ( 312). 



2. Make the lantern slides 

 with moderate intensity, then 

 they can be used with all lan- 

 terns, no matter what the source 

 of light (327). 



3. Make the picture small 

 enough so that all desired parts 

 can be projected (334). 



4. Take pains in mounting 

 the slides so that the frame will 

 appear suited to the subject 

 ( 334). 



5. In making slides direct on 

 the varnished glass, write finely, 

 neatly and clearly ( 316). 



6. Printed or written matter 

 on the slide should be large 

 enough to be read by all in the 

 room (325). 



7. Mark or spot the lantern 

 slides so that they can be in- 

 serted in the holder without 

 hesitation ( 335). 



8. Label every lantern slide 

 so that any one can tell what it 

 is ( 337)- 



9. Store the lantern slides so 

 that they can be found quickly 

 (338). 



Do NOT 



1. Do not use odd sized 

 pieces of glass to make lantern 

 slides on. 



2. Do not make the lantern 

 slides so opaque that only the 

 best electric lanterns can ex- 

 hibit them. 



3. Do not make the picture 

 on the slide too large to be 

 exhibited. 



4. Do not mount the slides in 

 a slovenly, inartistic manner. 



5. Do not use nourishes in 

 writing on the varnished slides. 



6. Do not reduce the written 

 or printed matter so that it 

 cannot be read in the screen 

 image. 



7. Do not leave the slides 

 unmarked and expect every 

 chance operator to insert them 

 properly at railroad speed. 



8. Do not leave the lantern 

 slides unlabelcd, for no one else 

 can make the best use of them. 



9. Do not store the slides in a 

 miscellaneous heap.
