1905-1906.J 333 



Lough Neagh, passing down the centre of Ireland, sending off 

 side-currents into' Carlingford Bay and north of Howth on its 

 way, a minor stream probably reached Galway as suggested in 

 Mr. Kilroe's paper, a supposition interestingly supported by the 

 discovery by Mr. J. O. Campbell during our Club's visit in 1896 

 of an Antrim flint on one of the Aran Islands in Galway Bay. 

 Mr. Kilroe informs me that Antrim, flints have a good distribu- 

 tion westward, and he recently found one in coarse sandy 

 alluvium in Co. Limerick, which must have travelled west in ice 

 and down the Shannon valley, probably in river drift. In 

 response to my mention of the N.N.W. rhyolite erratics he 

 writes : -—"All I have seen of the drifts since my original paper 

 on the Ulster ice-flow has confirmed me in the opinion that 

 there must have been an overwhelming flow . . . from 

 Scotland over Ulster, and that this was followed by a flow 

 northward and southward from Hall's axis of Irish distribution 

 — perhaps N. by W. in Antrim, northward through Co. Derry, 

 and N.N.E. through Donegal. I should not say that this 

 northerly flow or any part of it constituted part of the over- 

 whelming Scottish ice, though materials carried westward by 

 the latter may have been subsequently carried northward and 

 southward from the region indicated by Hall, extending from 

 South Antrim to Galway." Our own observations incline me 

 to question whether the Scottish ice swept westward over 

 Donegal as Mr. Kilroe indicates, but these points are purely 

 personal speculations to be refuted or confirmed by further 

 investigation. 



In conclusion I cannot speak too warmly of the fascination 

 of erratic-hunting, and the triumphant joy of bringing home a 

 handful of unfamiliar fragments ; of many pleasant days spent 

 in the open-air along the shore or on breezy hillsides, till the 

 icefields of the past became living realities to us, and we almost 

 seemed to share in their irresistible onward movement. Neither 

 can I conclude without a grateful reference to the many un- 

 dying friendships cemented by mutual tastes and mutual toil 

 and study that will ever cluster round the memory of our 

 pleasant Field Club Excursions !
