fine. They have no feature of botanical interest beyond a number of such 
plants as are contained in the other lochs of the neighbourhood, and such 
need not, therefore, be independently described. 
The plants that flourish in and about this series of lochs, from Loch 
Enoch to the Dungeon Lochs, are ■ as follows : — Lobelia Dortmanna, 
Littorella lacustris, Isoetes lacustris, Juncus fluitans, Myriophyllum alterni- 
florum, Sparganium natans, and Potamogeton polygonifolius, all abundant; 
Subularia aquatica, Callitriche hamulata, Utricularia vulgaris, U. intermedia, 
Scirpus fluitans, Sparganium minimum, and Castalia speciosa, var. minor, 
all more or less scarce. Characese are apparently scarce. Batrachospermum, 
Ulothrix, Mougeotia, Zygnema, Dickieia, etc., are frequently very abundant. 
Heleocharis palustris, Eriophorum vaginatum, E. polystachion, Carex 
rostrata, C. Goodenovii, C. filiformis, and Equisetum limosum are all 
abundant. Menyanthes trifoliata, Juncus effusus, J. lamprocarpus, J. 
acutiflorus, J. supinus, Carex binervis, C. flacca, var. stictocarpa, and 
dwarf forms of Ranunculus Flammula, Caltha palustris, Cardamine 
pratensis, and Hydrocotyle vulgaris are all more or less scarce. The follow- 
ing are some of the most conspicuous Bryophytes that occur, either in the 
water or clothing the rocks of the shores. A number are distinctly 
terrestrial forms, yet they constitute such a feature of the shores and are 
so inextricably associated with the loch that an enumeration of the flora 
would be incomplete were they excluded : — Sphagnum sp. abundant on 
boggy shores, Blindia acuta, Grimmia apocarpa, var. rivularis, Rhacomitrium 
aciculare, Fontinalis antipyretica, Aulacomnium palustre, Pterygophyllum 
lucens, Philonotis fontana, Brachythecium rivulare, Hypnum fluitans, H. 
revolvens, H. falcatum, H. scorpioides, H. commutatum, H. cuspidatum, H. 
uncinatum, Dicranella squarrosa, Scapania undulata, S. sub-alpina, Nardia 
compressa, N. emarginata, and N. scalaris. The foregoing species occur 
more or less in water, and the following in drier situations : — Dichodontium 
pellucidurn, Dicranella heteromalla, Dicranum fuscescens, D. Scottianum, 
Grimmia apocarpa, Rhacomitrium lanuginosum, R. heterostichum, Hedwigia 
ciliata, Trichostomum tortuosum, Orthotrichum rupestre, Bryum alpinum, 
Mnium punctatum, Heterocladium heteropterum, Pterogonium gracile, 
Plagiothecium undulatum, P. elegans, Thuidium tamariscinum, Hypnum 
cupressiforme, Frullania tamarisci, Pleurozia cochleariformis, Anthelia julacea, 
Diplophyllum albicans, Mylia Taylori, Pellia calycina, P. epiphylla, etc. 
Loch Trool is 246 feet above sea level, and is 1J miles long by \ mile 
wide, with a maximum depth of 55 feet. It is approached from Loch 
Dee through a narrow, rugged, and trackless pass about 3 miles long, 
This loch affords a splendid piece of highland scenery, which is probably
