Alice Morse Earle,
Child Life in Colonial Days
“ To the forest the scholars turned for the ever plentiful birch bark, which formed a delightful substitute to cipher on instead of paper. Among the thrifty Scotch-Irish settlers in New Hampshire and the planters in Maine, sets of arithmetic rules were copied by each child on birch bark and made a substantial text-book. Rolls of birch bark resembling in shape the parchment [80] rolls of the Egyptians and lead plummets seem too ancient in appearance to have been commonly employed in schools within a century in this country. ”
