Definition of "smoothe"

And I suppose thou can’t smoothe almost any seams and dents; never mind how hard the metal, blacksmith?

1851, Herman Melville, Moby-Dick

Garden peas are divided into three clases, the wrinkled, the smoothe and the sugar peas or those with edible pods. The wrinkled sorts are conceded to be sweeter and better flavored than the smoothe ones, but the smoothe varieties are considered hardier and therefore better for extra early planting.
