Dúnedain Survival Rations

[Snowdog]

Unfinished Tales the other night I came across the following passage written about the time of Isildurs death:
P.276
"Each of the Dúnedain carried in a sealed wallet on his belt a small phial of cordial and wafers of a waybread that would sustain life in him for many days - not indeed the Miruvor or the Lembas of the Eldar, but like them, for the medicine and other arts of Númenor were potent and not yet forgotten"

I had always taken the meaning Tolkien had for these mentions of when the lore was "forgotten" that he meant it was forgotten today, not anytime before, or even soon after the War of the Ring.
