the forest, members of the Mnium family. They are particularly 

 noticeable for the leaf development. The leaves are often quite 

 large and more nearly resemble the leaves of seed-bearing plants. 

 A plant of the species Mnium affine ciliare is a faithful copy, 

 in miniature, of a compound leaf of a seed-bearing plant, with 

 numerous leaflets. 



Out in Wildcat Ravine, just where the brook spreads itself 

 out quietly upon the top of the cliff before it takes its downward 

 plunge over the mountain side, we shall find the large-leaved 

 Mnium punctatum elatum. Its leaves are especially large and 

 have a distinct mid-vein. It prefers the ooze on partly submerged 

 rocks. The male heads of the Mnium and those bearing the 

 capsules are very frequently found mixed. Beginners may mis- 

 take the two for separate species. 



Our book has told us about the Bryum family, much resembling 

 the Mniums, and of the difficulty of identifying them without a 

 microscope. But there is a giant Bryum which seems easy to 

 recognize if we can find it. Its favorite haunt is secluded from 

 human eye in rich moist loam on shady, sheltered, almost in- 

 accessible cliffs. We take a scramble down over the rocky sides 

 of Round Top and behold! here it is. The rosettes of leaves at 

 the top of the naked stems, looking like perfect little green roses, 

 are arranged, as only nature can arrange her creations, in sur- 

 passingly beautiful masses. The Bryum roseum fruits infre- 

 quently but sends forth new shoots from underground stems 

 called stolons. 



In your mountain walks, if you come upon a rock of con- 

 glomerate, a fragment of an old seabeach now resting quietly 

 in the shade, look closer and you will be apt to find in the niches 

 of its pebbly surface, bunches or tufts of what appears like green 

 wool. This is the woolly moss or Bartramia pomiformis. It 

 gets its last name from the fact that its capsules are quite apple- 

 like in form. 



Nature makes haste to hide the bare blackness of burned-over 

 ground. How soon we notice Epilobium, the fire-weed, with 

 its racemes of conspicuous purple flowers standing like sentinels 

 where a fire has raged. But if we get closer to the blackened
