Is it a hot-house plant, which must be framed and glassed, lest March, that bold young fellow, should shake the life out.of it in his rough play among the flowers? or is it a hardy shrub, which rejoices when the wild winds course along the heather or howl above the crest of Lebanon ' We need, believe me, the bravery of godliness to bear true witness for our Master now.
