One follows a horizontal river run. That is Joyce’s “A way a lone a lost a last a loved a long the” which is the end of Finnegans Wake which famously links back to the riverrun opening.
The other is oriented on a vertical axis and follows a slope both in its run and situation.
The photo by Stefan Powell conveys a little of the slight incline in the alley where this inscription from bpnichol is to be found. (There was audio at the Murmur project of Christian Bök reading the incised words.)
Both whatever their orientations play on vowel currents and waves, float as easily as place names here brought in proximity — Dublin’s River Liffey or Toronto’s Lake Ontario.
And so for day 338
