Infection would seem to be brought about chiefly by westerly winds (in Germany), which carry diseased leaves or fungus-si)ores from infected places. Large areas run greater risks than small patches or young trees naturally sown out. Seed-beds of Scots fir should not be placed under the drip of older trees of the same kind, particularly if this fungus is known to exist there.
