highly finished instruments, admirably adapted to every purpose 

 connected with agriculture, horticulture, floriculture, and pomol- 

 ogy, has rarely been collected in any one exhibition in the United 

 States. We shall name here only a few articles as of recent in- 

 troduction or improvement, calculated to effect a saving in the 

 labor of the husbandman, or to accomplish in a more perfect and 

 economical manner important results in the management of farms, 

 viz : mowing machines ; mowing and reaping machines ; mowing 

 reaping and raking machines; improved churns; cheese press; 

 wire fence ; cider mill and press ; threshing and cleaning ma- 

 chines ; draining tile; sub-soil plows, &,c., particular reference to 

 which will be found in our premium list or the reports which 

 follow. 



The machine department was unusually full, presenting speci- 

 mens of the most highly finished and accurate machinery, togeth- 

 er with inventions and improvements designed for the accom- 

 plishment of important utilitarian purposes. The press for space 

 to exhibit moving machinery, induced the manageis to enlarge 

 this room by adding sixty ftet to its length previous to opening 

 the fiiir. The room is now 220 feet long by 25 feet wide, with 

 a tight roof, admirably adapted for light and ventilation. It is 

 furnished with a steam boiler of ample size, a twenty-five horse 

 power steam engine, a line of sliafting extending 180 feet, with 

 counter-shafting, pulleys, &c. Excepting the necessary reserva- 

 tion made for the accommodation of visiters, Avhich enabled them 

 to view every thing with perfect safety, the room was filled with 

 machinery, constituting an attraction of unusual interest. The 

 space allotted to visiters, was filled by them almost every hour 

 during the time it was open. Of new inventions, we will here 

 allude to a few. Three machines for crushing hard substances 

 were on exhibition, than which, up to the present day, no ma- 

 chinery has been more susceptible of improvement, or seems now 

 to be in greater demand. Among them the quartz crusher, in- 

 vented by Mr. John W. Cochran, appeared to be pre-eminent, re- 

 ducing that material with astonishing rapidity to almost an im- 

 palpable powder, at a cost far less than any plan heretofore de- 

 vised. A gold beating machine was exhibited in operation, by 

 William Vine, Jr. This is the first attempt at making leaf gold
