From a few sources of information we gather some clews as to the size of the schoolhouse generally. The house proposed by the Goshen Meeting in 1782 was to be 27 feet square from out to out and to cost about £150.[818] The new one proposed at Falls some twelve years later was to be somewhat more pretentious being twenty-two feet by thirty and having two stories. Its cost was estimated at £200.[819] We infer from the minutes that a building was badly needed at Falls, the old roof being “very leaky and the ceiling about to fall.” In spite of this fact it does not appear that the house was erected until about 1799; the final dimensions decided upon were twenty-six feet by twenty-four, one story, and a cellar of the same dimensions.[820] It is not certain how much space was actually devoted to the use of the school room, since the building doubtless accommodated the master and his family at the same time. The schoolhouse begun in Philadelphia about 1701,[821] was to be twenty-four by sixty feet. Another one in 1744, built on the Forrest property, was to be about sixty by thirty-five feet, two stories high, with a basement underneath raised three feet above the surface of the ground.[822] The cost of the last building when completed in 1746 was £794.[823] Anthony Benezet, who apparently was teaching in an old building, made complaint in 1744 that it was “too hot in summer and too dark in winter” and therefore urged that a window be put in the south side.[824] The writer has found a single instance to indicate how the school building was heated. Judging from such meager data we would say that the first schools probably up to 1715 or 1720 were heated by the old-fashioned brick stoves. They were at any rate employed in some, but were beginning to lose their popularity in that period. One was removed in 1715 and an iron stove substituted for it.[825] [Sidenote: Number of children attending schools] [Sidenote: Two classes: the “pay” and the “free” scholar]
