Three discretionary premiums (gold or silver medals), to be 

 determined by the Board of Managers. 



The grains and vegetables will be required to be exhibited at the 

 Farmers' Club, on Tuesday, the 15th day of December next. Those 

 deemed entitled to the premium will become the property of the 

 Institute, and will be distributed at the Farmers' Club. 



The new seedling fruit must possess sufficient merit to warrant their 

 general cultivation. They may be presented at any meeting of the Club. 



The essays must be designated by a nom de plume, which is also to 

 be superscribed on an envelope, inclosing the name of the author. 

 After the judges have decided upon those entitled to the premium, 

 the rejected essays will be returned to the authors, with their accom- 

 panying envelopes unopened. The successful essays will be pub- 

 lished in the Transactions of the American Institute ; but the copy- 

 rights will remain with the authors. 



Inventors and others wishing to bring before either of the Clubs 

 herein named, any article for examination and competition, may pre- 

 sent it at the rooms of the Institute, to Mr. John W. Chambers, 

 Recording Secretary of the Board, at any time during business hours. 

 Suggestions are especially invited from manufacturers, as to improve- 

 ments desired in their own experience. All communications addressed 

 to James Renwick, LL. D., Corresponding Secretary of the Institute, 

 will meet with immediate attention. 



The Polytechnic Association meets every Thursday, at 7| o'clock, 

 p. M., and the Farmers' Club every Tuesday afternoon at li o'clock, 

 at which times the articles or subjects presented will receive the 

 attention and examination of the respective clubs. 



The applications for the premiums were not so numerous as wo 

 anticipated, from which we are led to conclude that the public mind 

 has been more absorbed on the subject of war than the more peace- 

 ful pursuits of science and agriculture.
