Lough Neagh, passing down the centre of Ireland, sending off 
side-currents into Carlingford Bay and north of Howth on its 
^’ a , m r stream P roba bly 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 m 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 
wntes 1 - ~t’AU 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 
m 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 !
