Sprague, B., Notes on the Formation and Flora ofashingle 

 Island in the River Orchy, Dalmally, Argyll. (Trans. Edin- 

 burgh Field Nat. & Micr. Soc. V. p. 290—315. 3 maps. 1906.) 



This is a careful study of the changes traceable in the growth 

 and shapes of an Island formed of sniall stones and sand in the 

 bed of a stream flowing from mountains, the Island being situated 

 in the lower part of the river's course where the Valley is culti- 

 vated. The maps compare the forms of the Island and the banks of 

 the river as shown in the Ordnance map of the old survey (1855 — 

 1876) and as they existed in 1905, to illustrate the growth of the Is- 

 land, and the progress of its being occupied by plants. 



A list is given of all the plants found on the island, except a 

 few of the more critical species; and the distribution of each one 

 present on the banks of the stream and adjacent fields is stated, 

 with a view to determine whence the plants on the island had 

 come. The assemblage is analysed also to determine the adaptations 

 favourable to the migration of the several plants and to their colo- 

 nising the island. The conclusion arrived at is that a very large 

 percentage of the flora was probably derived from the banks and 

 fields very close to the island or only a little way up stream. A 

 few cultivated species were probably outcasts from not far up the 

 Valley; and only a small contingent of species could be referred to 

 the flora of the mountains near the sources of the Orchy and its 

 tributaries. J. W. H. Trail.
