DRYING HOUSE FOR HERBS.
From the rafters of the roof of the Drying House are suspended in bunches all the herbs that the grower cultivates. To accelerate the desiccation of rose leaves and other petals, the Drying House is fitted up with large cupboards, which are slightly warmed with a convolving flue, heated from a fire below.
The flower buds are placed upon trays made of canvas stretched upon a frame rack, being not less than twelve feet long by four feet wide. When charged they are placed on shelves in the warm cupboards till dry.
