THE BOTANY OF THE BAEEOW. 17 



" Barrow Navigation Company " I believe, on one side or the other 

 of the river, or along some canal close by. This objectionable and 

 injurious construction has banished many interesting plants from 

 its side of the Barrow, and limited my choice of walking con- 

 siderably, as I was of course compelled to follow the side of the 

 river where the path did not lie. Kind remarks were frequently 

 addressed to me on the subject, but I paid them no attention. On 

 excursions like this, if there is anything whatever to be gained 

 by asking a peasant the way, it is to learn which way he 

 considers impossible and the worst, and to choose that without 

 a moment's hesitation. Below Athy I kept the right bank of 

 the river in District III. GeraniiDii pyrenaicum and Stellaria 

 glauca were seen and most of the larger river plants already 

 mentioned. Myriophyllum spicatum was noticed, and the large 

 dock has become abundant. At Kilmoroney Crepis paludusa and 

 the white Lychnis were the only novelties. In consequence of 

 my delay in the morning it was dusk when I reached Magauey 

 Bridge, and I luckily caught a train to Carlow, where I slept that 

 night. 



On the 25tli I drove out to Maganey. Between Carlow and 

 Maganey I noted Orchis pyramidalis, Geranium pyrenaicum, Viola 

 odorata, Lithospermum arvense, and Ch(BrophylLum teynuluin. From 

 Maganey Bridge to Carlow Carex acuta, C. vesicaria, Thalictrwii, 

 Poa, Lysimachia, Riimex, and Myriophyllum of the large river kinds, 

 all occurred to Carlow. Sagittaria was seen in one place, and by 

 Mark's Grange, Polygonum Bistorta is a common weed in an old 

 meadow, with Orchis pyramidalis and Chlora perfoliata. About half- 

 way between Maganey and Carlow I left Queen's County, and the 

 Barrow lies entirely in Carlow and District III. At Shrule Castle 

 I noticed Car ex muricata for the second time. Near Knockleg 

 Stellaria glauca is common in a rushy field, and Nasturtium amphi- 

 bium occurred again ; it had been absent for many miles. Potamo- 

 geton perfoliatus and P. heterophyllus are common. Back to lunch 

 at Carlow in afternoon. I noticed Avena Jiavescens close to the 

 town. After Carlow I saw Sagittaria once more, and near Milford 

 Stellaria glauca, Carex acuta, and the large Rumex. At Milford the 

 Barrow begins to grow pretty, and its beauty here is much enhanced 

 by the picturesque situation of some handsome mills amongst 

 timber, by a lovely bridge with three high semicircular arches. 

 On the bridge I noticed Sagiiia ciliata. There I crossed to the left 

 bank to avoid the tow-path, and found in thickets Lycopus europceus. 

 A little farther down was a wonderful display of yellow Iris in full 

 flower. It formed an inland belt of about fifty yards for more than 

 half a mile parallel to the river ; outside it an abundant growth of 

 Caltha jyaliistris, a,t the water's edge and out as far as shallow Poa 

 aquatica, and in the deep water Potamogeton lieterophyllus and Spar- 

 ganium minimum form the predominant vegetation. About two and 

 a half miles below Milford, on hedge-banks down the Barrow, I 

 gathered Clmrophyllum temulum again, and in plenty about three- 

 quarters of a mile from Leighliu Bridge. CEnanthe Phellandrium is 

 always frequent. At Leighlin Bridge Senehiera didyma, Sambucus
