uurastus (present participle of)
Progressing slowly and laboriously.
Slow, laborious progress.

I'd count not wearisome / Long toil, nor enterprise, / But strain to reach it; aye, with wrestlings stout / And hopes that even in the dark will grow / (Like plants in dungeons, reaching feelers out), / And ploddings wary and slow.
