decreasing species in Ireland.]

the present writer in 1907, that he could remember, when a boy, his parents 
speaking of a mill on this stream as then only recently destroyed, the date

the Polygonum has its headquarters and may possibly be the remains of

tinued in its present position for at least sixty years,
