 cause of popular education. 



Mr. Crum's character was marked by clear intelligence and strong 

 practical sagacity, unbending love of truth and justice, frank sincerity,

 so unselfish and of such retiring modesty that he shrunk from the slightest 

 display. Few men have lived more usefully, or have died more esteemed and 

 regretted.
