With the rebuilding of the Hall by the President, the Pennsylvania Horticultural Society is ready to resume its annual exhibitions, for which it has always been so famous. It has just issued its programme for the year. September 19th, 20th, 21st and 22nd is the time set apart for the annual exhibition. The premiums are very good, $30 and $25 for the best twenty-five ornamental plants and other flowers. Cut flowers, designs, fruits and vegetables receive due attention. A. W. Harrison, Recording Secretary, Philadelphia, will furnish programmes to all applicants.
