“I knew one boy who passed through several schools a dunce and a laughing-stock; the National Board and the Intermediate Board had sat in judgment upon him and had damned him as a failure before men and angels. Yet a friend and fellow-worker of mine discovered that he was gifted with a wondrous sympathy for nature, that he loved and understood the ways of plants, that he had a strange minuteness and subtlety of observation—that, in short, he was the sort of boy likely to become an accomplished botanist.”
