If it were not for the pretty notice of Moss in the last passage (6), we should be inclined to say that Shakespeare had as little regard for "idle Moss" as for the "baleful Mistletoe." In his day Moss included all the low-growing and apparently flowerless carpet plants which are now divided into the many families of Mosses, Lichens, Club Mosses, Hepaticæ, Jungermanniæ, &c., &c. And these plants, though holding no rank in the eyes of a florist, are yet deeply interesting, perhaps no family of plants more so, to those who have time and patience to study them. The Club Mosses, indeed, may claim a place in the garden if they can only be induced to grow, but that is a difficult task, and the tenderer Lycopodiums are always favourites when well grown among greenhouse Ferns; but for the most part, the Mosses must be studied in their native haunts, and when so studied, they are found to be full of beauty and of wonderful construction. Nor are they without use, and it is rather strange that Shakespeare should have so markedly called them "idle," or useless, considering that in his day many medical virtues were attributed to them. This reputation for medical virtues they have now all lost, except the Iceland Moss, which is still in use for invalids; but the Mosses have other uses. The Reindeer Moss (_Cladonia rangiferina_) and Roch-hair (_Alectoria jubata_) are indispensable to the Laplander as food for his reindeer, and Usnea florida is used in North America as food for cattle; the Iceland Moss (_Cetraria Islandica_) is equally indispensable as an article of food to all the inhabitants of the extreme North; and the Tripe de la Roche (_Gyrophora cylindrica_) has furnished food to the Arctic explorers when no other food could be obtained; while many dyes are produced from the Lichens, especially the Cudbear (a most discordant corruption of the name of the discoverer, Mr. Cuthbert), which is the produce of the Rock Moss (_Lecanora tartarea_). So that even to us the Mosses have their uses, even if they do not reach the uses that they have in North Sweden, where, according to Miss Bremer, "the forest, which is the countryman's workshop, is his storehouse, too. With the various Lichens that grow upon the trees and rocks, he cures the virulent diseases with which he is sometimes afflicted, dyes the articles of clothes which he wears, and poisons the noxious and dangerous animals which annoy him."
