The belief shared by all observers, that the herbs whichdid not reappear during the first season after the eruption hadbeen killed, was, of course, due to the presumption that a com-paratively short period of covering would prove fatal at Kodiak.

Cultivation just before the eruption destro\ed most of the weedsand no new ones have been able to start.

The death of grass in a lawn,where a board is allowed to lie for a few weeks, is familiar to was supposed that burial under a foot of volcanic ash wouldhave the same effect. I was, therefore, very much astonishedto find that the plants at Kodiak were able to recover from suchburial. Later observations, however, showed that the recovery Nov., 1918] Recovery of Vegetation at Kodiak 33 at Kodiak was altogether eclipsed by that shown in some areason the mainland, where many plants
