School-room without Apparatus,” “Health Notes,” 
“Common Sense in the Schoool-room,” * Out-door 
School,” ete., ete.. have run through five years past, 
and will be continued the next five years. The 
circulation in Pennsylvania is as large as the bona 
fide circulation of any other educational journal, 
whether published in or out of the State, while it 
also has a large general circulation, particularly in 
the South, where the editor has been State Institute 
Conductor a number of terms. All the articles are 
original, short, sharp, and common sense. Seventy- 
Jive cents @ year, payable whenever the subscriber is
