ther ; and if any one {trolled from the reft at too 
great a diftance, the dog would fpring up, head 
the horfe, and bring him back to the company. The 
proprietor of thefe horfes is an Indian in Talaha- 
fochte, about ten miles diftance from this place, 
who, out of humour and experiment, trained his 
dog up from a puppy to this bufinefs : he follows
