The existing organization and methods in school work began in 1838, when the state board of commissioners of common schools (later replaced by a board of education) was organized, with Henry Barnard at its head.
Barnard had observed the same phenomenon at Chicago.
Yet more conclusive are the observations of Maxwell Hall at Jamaica, who reached conclusions identical with those of Barnard and Newcomb, from observations of the base of the light at the close of twilight, which he estimated at 60° in the line through the sun.
It has been seen to stretch across the sky at midnight by several observers, especially Barnard, to whom it appears 3° to 4° wide.
Barnard, the most successful observer, assigns diameters of 5° or even 10° or more.
