44 AUTOBIOGRAPHY. 



dering spectators. Here I formed a class of 

 over one hundred and fifty. 



My next effort was made at Lancaster, a city 

 of no small magnitude or interest, as I there 

 formed a class of nearly two hundred, the major 

 portion of whom were Germans, or of German 

 descent. On the last day of my stay in that 

 city I received a testimonial from a leading 

 banker of the place, which I give below : 



LANCASTER, PA., October 16, 1869. 

 PROF. O. S. PRATT : 



Dear Sir : I take pleasure in testifying to the success of 

 your system of controlling vicious horses as applied to my 

 colt. Since you handled and drove him without backing- 

 strap, I have driven him twice without his showing the least 

 fear or disposition to return to his dangerous habit of 

 kicking. 



I believe you have perfectly taught him to work without 

 kicking, and that he will not forget the impression your 

 treatment made on him. Your system is so easily learned 

 and can be so quickly applied, that it is the owner's fault if 

 his balky, runaway, or kicking horse, ever forgets what you, 

 or any member of your class can teach him in half an hour. 



Every one who owns or drives a horse ought to join 

 your class. Yours, 



B. J. McGRAUN, 

 President First National Bank.
