 stone, which was the cause of the horse's illness." 

 This, the miller, of course, neglected to do ; but 

 his dogs made the discovery for him : it was a 

 large round stone, broken, from which circumstance, 

 we infer that it had been at first a soft or earthy

 Yearsley, of High Holborn, has invented one 

 which he " warrants not to clog," and thus ob-
