The plan of having instructive lectures on the plants, fruits and vegetables exhibited, inaugurated by the Germantown Horticultural Society a year ago, has added largely to the attendance and membership of the Society. The lectures are generally by Prof. Thomas Meehan, though other members make occasional addresses. The Royal Horticultural Society of London has adopted the same plan. A recent Gardeners' Magazine says of a late exhibition: "Not the least pleasing part of the meeting was the remarkably interesting and instructive lecture by the Rev. G. Henslow on the objects brought before the Floral Committee".
