This body holds its annual exhibition this year in Fairmount Park, Philadelphia, from September 8th, to September 20th, in the Main Building of the Old Centennial Exhibition. The holding of a State Fair in one building like this, is something to reflect on, and nothing like this has ever occurred before. If there are yet any persons who have never seen one single building which covered twenty acres of ground, they will probably not neglect to see it with the additional attraction of the State Fair. In the schedule we note liberal premiums for fruits and vegetables, and ornamental plants, flowers, designs, etc.
