READING, BOOK PRINT, AND GLASSES

Write a sentence on your slate. Write the same sen- 

 tence on paper with your pen. The last one is so much 

 easier to read that we know at once that it is the best for 

 the eyes. Ink should always be jet black, even when it 

 is first put on paper. Blackboards and slates should be 

 clean that the writing may 

 show plainly. Dim marks 

 hurt the eyes. The easier 

 it is to see a thing the bet- 

 ter it is for the eyesight. 

 This is just as true of 

 books and newspapers as 

 of blackboards and writ- 

 ing paper. 



Here is a newspaper. I 

 pick it up from the table 

 and I notice several inter- 

 esting points about it. 

 Some of the letters are 

 large and some are small ; 

 some of the lines are near 



together and some are far apart ; some of them are short 

 and some are long. On the first page of this special paper 

 there are seven columns and most of the letters are 

 no larger than these in this book. On the second page, 

 however, there is but one column. It is a monstrous 

 advertisement with large letters and lines far apart.
