in the grass-mixture samples; but none of these American plants are 

 species which have as yet effected a lodgment in Ireland. Tor the rest, 

 we find, as in the Achill samples, a number of species long since arrived 

 on the island as natives, and others which have followed agriculture 

 thither. The plants not known on the island indicate (exclusive of 

 the American ingredient already referred to) a southern and eastern origin 

 of the seed, as in the case of the Achill batch of samples. 



Seeds out of hay from Roonah. — This hay was grown a mile from Koonah 

 on an old meadow bottom which had not been tilled for twenty years. The 

 last crop was oats, after which the grass was allowed to grow up naturally, no 

 seed being sown. The sweepings yielded seeds of the following species : — 



N Ranunculus ?repens Myosotis sp. 



Silene sp. N Rhinanthus Crista-galli. 



N Cerastium triviale. N Prunella vulgaris. 



* Stellaria media. N Plantago lanceolata. 



* Spergula arvensis. Atriplex sp. 

 Trifolium ?procumbens N Polygonum Hydropiper. 



N Heracleum Sphondyliuin. * P. lapathifolium. 



N Bellis perennis. N Rumex Acetosa. 



N Chrysanthemum Leucanthe- N Luzula campestris. 



mum. N Carex ovalis. 



Centaurea sp. N Anthoxanthum odoratum. 



ina communis. Holcus mollis. 



N" Hieracium Pilosella. N Arrhenatherum avenaceum. 



N Hypoehaeris radicata. * Bromus mollis. 



* Crepis virens. N Agropyron repens. 



It will be seen that the bulk of these plants (marked N) are natives on 

 Clare Island ; but that some others (marked *) are of doubtful standing, and 

 might have been originally introduced in some such manner as the present 

 case, in which the hay, being landed, is carried on pony-back along the roads 

 of the island, seeds being no doubt scattered in the process. The species 

 present in this sample which are absent from the island are almost nil, the 

 doubtful plants belonging in all probability to common species occurring on 

 the island. 



Oats for feeding horses and fowl. — This was received as a fair sample of 

 the oats used for the purpose ; and I was informed that no screenings or 

 very dirty oats are imported for feeding fowl. Purity about 98 per cent. 

 Nine-tenths or so of the impurities consisted of Galium Aparinc, the full 

 list being 



* Brassica Sinapis * Stellaria media. 

 Brassica sp. N Galium Aparine.
