WHEN THE CHILDREN ASK FOR 



DIXON'S PENCILS 



don' t put them off and give them others that you 

 think are just as good ; the little ones know what 

 they want. The lowest in price is seldom the cheap- 

 est, but the best is always the cheapest in the long 

 run. We make fat pencils with fat leads for fat 

 little hands ; these lighten the work of the teacher 

 immensely, as tired hands cannot do their work 

 well. We will be glad to send to any teacher that 

 sends 10 cents in stamps and mentions this publica- 

 tion samples that will be of interest.
