I should mention that we have so far followed the right or west 

 bank of the river. South of Thurles the last three mentioned 

 plants and (Enanthe phellandrium are still frequent. Between 

 Thurles and TurtuUa Mill I noticed Menyanthes trifoliata, Potamo- 

 geton perfoliatus, P. lucens, and Carex riparia. At the Mill the large 

 water millfoil, Myriop)hyllum verticillatum, a rare plant in Ireland, 

 was observed ; and between that and Holycross I gathered Ranun- 

 culus lingua, Solanum dulcamara, Alliaria officinalis, and Orchis morio. 

 These occurred at intervals along the river to Twoford bridge, and 

 along here tributaries and heavy dykes rendered our journey very 

 laborious, and we crossed to the left or east bank. We found 

 willows overhanging these ditches often very serviceable ; and even 

 if the bough did give way and capsize the leader into the water, he 

 was probably most of the way across at any rate. We had, however? 

 determined, to cross all obstacles, so that a swim more or less was 

 not important, and up to this the width of the water to be crossed 

 was trifling. About two or three miles below Twoford bridge the 

 river takes a wide bend westwards, and here there is a deep and 

 impenetrable swamp. It was on the margin of this swamp I 

 gathered Eriophorum latifolium, a very scarce plant in Ireland, and 

 there appeared to be abundance of it. The marsh may be distin- 

 guished by the name of Aughakilleen. In the same marsh also I 

 noticed Pedicidaris palustris, Carduus pratensis, Eupatorium canna- 

 hinum, Pinguicula vulgaris, Schcenus nigricans, and Carex vesicaria. 

 In some places the latter was so abundant that as sheets of its leaves 

 moved in the wind in the light of a low sun, the effect was that of a 

 meadow of shining golden yellow, while as a contrast the glaucous 

 foliage of Carex ampullacea gleamed along the flooded fields like 

 silver. On the higher land above this marsh Orchis morio is 

 frequent, and again lower down about Camus bridge. Here also 

 occurred Nasturtium palustre, Lysimachia vulgaris, and Thalictrum 

 flavum ; and near Castle Lake corn-mill I gathered Potamogeton 

 pusillus. On this part of the river's banks to Grolden, Carex disticha 

 is frequent. In rich meadow ground on the east bank, a mile or 

 two above Golden, I gathered Bromus commutafus, a rare grass in 

 Ireland. It seemed native in this locality. At Grolden, an ex- 

 quisitely situated hamlet on the river, we obtained snug, clean, and 

 primitive hospitality from two captivating old ladies, in a pictu- 

 resque lodge, occasionally used by anglers. The news that Grolden
