hour gratuitously offered, no longer to leave to desultory ef- 

 forts a subject so essential to her prosperity. 



By order and in behalf of the Society , 



RICHARD PETERS, President,

 and a law for establishing County Agricultural Societies was 

 passed March 6th, 1820. — Several Counties have availed them- 

 selves of the provision of that Law. 



CoUinge-s Hinges. 



The annexed plate of Collinge's Hinges gives so correct an 

 idea of their construction, that any description is unneces- 

 sary. — They are calculated as well for doors as gates ; and 

 are made of different sizes. They move in oil, and totally ex- 

 clude air and dust; and after a trial of them near Philadelphia, 

 are preferred to any other hinges. The address of the inventor 

 is J. Collinge, Bridge Road, near the Marshgate, Lambeth, Eng- 

 land.
