" hills amid the air encountered hills, 



Hurl'd to and fro with jaculation dire," 



And evidently too to the advantage of the pudding stone: 

 for this is several hundred feet the highest, is more steep and 

 more easily broken up from its be J, so that its debris has 

 evidently gained upon the older rocks, and subjected some 

 of them to its dominion. 



In this valley the lichens, mosses and fungi, have planted 

 themselves thickly upon the bowlders and decaying logs 

 where they are secured by the dense foliage of the trees 

 from the too powerful rays of the sun and moistened by 

 the vapour of a small brook which here finds a passage. 

 You there see Sticta pulmonacea (Ach.) and Jungermannia 

 platyphylla^ fantastically fringing the rocks, while the ever 

 verdant Pdlypodium vulgare frequently crowns the top. 

 Parmelia saxatilis, caperatn, and others, several Lecanorce 

 and Lecideae, Peltidea canina, Poiena pertusa Ramalina 

 fraxinea and Cenomyce coccifera and rajigiferince. of Achari- 

 us, Hedwigia Jilijormis, Bartramia crispa, Polytrichum 

 perigoniaie, several species of Hypnum, Dicranum, Ortho- 

 trichum, and many other genera grow there. On the de- 

 caying trees along this valley, you not unfrequently may 

 see the delicate Boletus versicolor' and betulinus, the elegant 

 B. cinnaharinus and lucidus, and the useful B. varius, velu- 

 iinus and igniarius, (Persoon.) Here too may be found 

 Agaricus alneus (Pers.) Dacedalea cinerea and Polyporus 

 abietinus of Fries ; various Thelephorae, Hydra, Clavariae, 

 Pezisce, he. And the margin of the brook has in many 

 places a carpet of Marchantia polymorpha and conica. 

 Near the northern extremity of this valley is a pond, in and 

 around which are many rare and interesting phenogamous 

 plants — such as Drosera rotundifolia and longifolia, Ku- 

 jphar advena and Kalmiana Nymphea odorata, tftricularia 

 striata (n. sp. Le Conte) Myriophyllum verticillatum, one 

 or two Charae, Cnicus lanceolatus, attissimus arvensis, dis- 

 color and muticus; Rhynchospora glomerata and alha Na- 

 jas Canadensis and Scirpus tubterminalis (n. sp. Torrey 

 MSS.) In the outlet to this pond grows the singular Spon- 

 gia jiuviatilis of Linnaeus. 



But to return to the granite. Along the southern and 

 central parts of Montague, it is greatly hid by the gneiss and 

 mica slate. In the northern part of the town, however,
