the fronds may be cut as sOon as the sori Or fruit-dots turn

enterprises. This constitutes a special department of nursery
practiw, and it cannot be discussed in this book ; but some of
the seed-becl nwthods ma>. be indicated as a supplement to
the discussion. Those who desire to inform themselves on
forest-tree nursery work 4wuld consult the state and federal
publicatit:;;s, ~hapt~s irk books on forestq., and Tourney’s
