BY taking a little trouble, pretty pictures may often be made out of fern fronds, considered useless in the greenhouse, or, at all events, by the use of a few which may be cut off and never missed. After the ferns have been removed, they should be dried between sheets of botanical drying paper; even old newspapers or blotting paper will answer the purpose. Presuming that a collection of dried ferns is at hand, a sheet of nice card board should be procured; some like white card board, others, nicely tinted - which is the best. The ferns should then be laid lightly on it, and arranged in the form of a bouquet, or in whatever shape desired. The position of each fern should be indicated before it is glued down, as after that it could not be well removed without marking the card board. Supposing the fronds to have been arranged according to taste, they should be lifted up again, and their backs glued with a fine brush, so as to make them stick to the paper. Should any gold or silver varieties be amongst those selected, they should be placed so as to show the colors of the under sides of the fronds. The light colored Moss, which is to be found growing on old trunks of trees, if interspersed through the ferns, tends to give the arrangement light and elegant appearance.

A wreath of ferns mounted in this way, has an effective appearance, if placed round or under a handsomely illuminated text. The fronds selected for mounting in this way, should be those of small and light looking varieties, as large and heavy growing fronds would make a small arrangement of this description look heavy. In this way a capital book of reference on ferns might be made up, each variety being mounted on a sheet of drawing paper or card board, and the name of the variety, height of growth, native country, etc., written under the fronds. It will be found astonishing how very quickly a collection of this kind can be got up as single fronds are easily obtained. - The Garden.
