Martha's Vineyard MA: ID'd Cottage 1870s photo by S.F. Adams Massachusetts V80

Stereoview of a cottage at Martha's Vineyard, Massachusetts . Back identifies the cottage, but I have trouble making out the first word. Looks something like Heahaw (Henhaw?) Cottage, Martha's Vineyard. Photographer is S.F. Adams, Oak Bluffs, Massachusetts. Adams also maintained a photography gallery at New Bedford, MA.
