Appreciates being befriended by a woman of such character. Will pass on her suggestions to Dr. Jane E. Robbins (1860-1946), Secretary of the Public Education Society. Comments on having a "'play-room' … as large and airy as possible, in every apartment or tenement," for the children, referencing Felix Adler (1851-1933). Written on "The Jacob A.
