James Gall, A Practical Enquiry into the Philosophy of Education
“ The nurseryman follows this plan with his trees, and with evident success, both in saving time, and room, and labour. When he sows his acorns, one square yard will contain more plants than will ultimately occupy an acre. It is only as they increase in growth, that they are thinned out and transplanted; and such should be the case in communicating knowledge to children. ”
