I'm looking for the second half of the following verse

O, ta fhios ag einne nach ag ol a bhimse
Do dearbhis feinig i gcuinne na tigh
Seanna mna an tsaol seo do craithig go leir me
At cruinniu spre suas da glean inning.

My spelling may not be great and I find the modern method of writing dreadful. I was taught using the gothic form, so apologies for that.
