clover feed, and about fix bufiiels of plafter of Paris to 

 the acre ; and by harveft time I had clo^-er all over the 

 piece, about twelve inches high, and which I mowed 

 in about two or three weeks after my wheat was cut ; 

 I believe 1 might have cut a full ton of hay otF from 

 each acre ; and I ana well fatisfied, that if I had not 

 put any plafter of Paris on it, I fbould not have had 

 any grafs that I could have cut. I have likewife fold 

 this manure to many people in this State, as well as in 

 New-Jerfey, Maryland, Delaware, 8cc. ; and after trial, 

 their applications to me have been very great, which 

 induces me to believe tliey have found the like benefits 

 from the ufe of it as I have myfelf. 



With refpect, I am thy friend, 



Robert Morris."

" I, Clement Biddle, Efq. Notary Public for the Con:>- 

 monwealth of Pennfylvania, duly commiffioned and 

 qualified, do certify, that Robert Morris, miller and 

 farmer of the county of Philadelphia, by whom the 

 foregoing ^ ritmg, certified by him in his hand-writing, 

 to me well icnown, is a perfon of good characler and 

 reputation, and that I have been on his farm, and have 

 feen great appearance of improvement in the produce 

 thereof, from the ufe of plafter of Paris ; and am of 

 opinion, that credit is due to his certificate before writ- 

 ten, relative thereto. The fa id plafter Oi Paris came 

 from Nova Scotia, and is of great repute. 



" In teftimony whereof, I have henrunto f;t my hand, 

 and fixed my notorial feal, at Philadelphia, this I Sib. 

 day of February, 1789.
