phylla, Pursh., or a form nearly akin to it, also occurs here. Grow- 

 ing with the Scirpus is the " Bayonet Juncus," everywhere com- 

 mon around these lakes. The species, as noticed in Dr. Gray's 

 Manual, is not accredited to any localities north of Tewksbury and 

 Plymouth, Mass., but I have collected good specimens in latitude 

 46°-40', and have found it fringing the shores of every large lake 

 in eastern Maine. In many of my specimens the bayonet leaf is 

 shorter than the diffuse parricle, in others the leaf is much above 

 the middle of the culm, and still is shorter than the remainder of 

 the stalk. But they obviously belong to one species, for, with 

 all these diiferences, these military rushes are not so widely dis- 

 tinct, as we see that many individuals are in the same army. 



Grand lake stream which connects Grand lake with the one just 

 noticed, is three miles in length, and has a broken and troubled 

 course among granite boulders and over slaty ledges. In the 

 water of this stream are found multitudes of the well-known 

 "Salmon trout," noticed in the report upon the Fishes of Maine. 

 This dwarfed salmon has strong and quick fins which give the fish 

 great celerity of movement. The tail is disproportionately large, 

 and, of course, aids very much in giving the fish power to stem the 

 strongest currents. The species is an exceedingly interesting one, 

 and deserves more study and attention than has yet been paid to 

 it. Its singular confinement to restricted localities — its likeness 

 to, and its difference from, the Salmon of the Penobscot — the pecu- 

 liar parasite infesting the scales, (very similar to the Caligus fig- 

 ured in Sill. Jour. 1st series, 70, by Dr. Dana,) all combine to make 

 the study one of much interest to Naturalists. 



At or near the mouth of Grand lake stream there is a stock-farm 

 kept by Mr. Gould. Some of the land on the southerly side of the 

 stream produces good hay in abundance, being, for the most part, 

 alluvial soil. By the aid of Mr. Gould and his team we carried 

 our luggage over the rocky road along the side of the stream. The 

 dam at the outlet of Grand lake is capable of resisting a great head 

 of water and is kept in good repair. The sand and gravel plains 

 over a part of the road from Mr. Gould's to the outlet, furnish a 

 good illustration of the open-plain vegetation of eastern Maine. 

 There is almost a total absence of Ferns, no one except the ever- 

 present "Brake," Pteris aquilina, attracting my attention. Occa- 

 sionally, on similar plains, one meets with Botrychium lunarioides 

 and its perplexing varieties, but such ferns are rare. Comptonia
