What is "upgathered"

Usage examples of "upgathered".

Say, on the noon when the half-sunny hours told that April was nigh, And I upgathered and cast forth the snow from the crocus-border, Fashioned and furbished the soil into a summer-seeming order, Glowing in gladsome faith that I quickened the year thereby.

On dithering feet upgathered, more and more, Brown strings towards strings of gray, with bristling spines, All migrants from green fields, intent on mire.
