ing masses, as also of" seeing the charming lakes of Derriclare and 

 Ina running into the very bosom of the mountains. Behind the inn 

 is a road leading to the green marble or serpentine quarries. At 

 Adams's 1 hired a car to take me to Roundstone. Mr. Martin, of 

 Ballynahinch grants the privilege of passing through his grounds, and 

 the distance by this route is six miles. After passing Ballynahinch 

 and getting to the river side, I was so captivated by the beauty of the 

 place that I sent on my car and determined to walk. The banks of 

 the river were bounded here and there by rocky knolls, now gar- 

 nished with the autumnal furze [Ulex nana), Erica cinerea, Calluna 

 vulgaris and Menziesia polifolia, the tall, elegant spikes of this last 

 overtopping the rest; altogether they formed a blaze of bloom. You 

 know my partiality for the heath tribe, and can appreciate my feelings 

 on the occasion. I never saw a more beautiful sight ; I dwelt upon 

 it with delight, and felt as if I could never sufficiently admire it. 



" Tarn thought his very een enriched." 



A unique object here presents itself, so singular as to attract every 

 passer by. A mass of rock, some ten or twelve feet in height, rises in 

 the middle of the stream, encircled near its top by a wreath of Poly- 

 podium vulgare growing in the utmost luxuriance. On leaving the 

 river bank, the rest of my walk was by no means so attractive. When 

 within a short mile of Roundstone, however, and close by the little 

 hamlet of Letterdife, my eye at once detected a plant or two of 

 Erica Mackaiana in the ditch-bank bordering the road-side. Return- 

 ing to reconnoitre the place, 1 found on the other side of the ditch 

 many plants of this very dubious species. This I consider an inte- 

 resting discovery, being a new locality for the plant, distant from the 

 original habitat at least two miles. Near this same place I also found 

 the very diminutive moss-like form of Calluna vulgaris, similar in 

 every respect to a specimen found by me in Donegal last year. 1 

 found the inn in Roundstone, kept by M'cAuley, clean and comfort- 

 able, and the landlord and his wife so very attentive, that 1 was in- 

 duced to make a considerable stay in the place, and was so fortunate 

 as to have as an associate a most agreeable and intelligent English 

 gentleman and zealous conchologist. I did not fail to make a visit 

 to Glan Iskey, a valley imbosomed in the beautiful mountain of 

 Urrisbeg, and the home, " Sweet home," of the Mediterranean heath, 

 or rather the Irish representative of that plant. What a peculiarly 

 interesting sight does this lonely ^ alley present, — can any spot be
