Mrs. Viola E. Richards of South Deerfield writes on October 18, 1920, that she watched a Yellow-bellied Sapsucker make two round holes in an apple tree. He drilled one shallow hole and then began on another, which he frequently left to return to the first, as if sap had gathered in one hole while he worked at the other. There is a recrudescence of sap in maple trees sometimes in autumn. The Indians are said to have drawn sap in October. Mrs. William F. Eldredge of Rockport, Massachusetts, writes.
