Contributions in geographical exploration . Photograph hy R. F. GriggsA DRIFT OF CLOSE PACKED ASH UNSUITED FOR PLANT planted here had not passed beyond the cotyledon stage in six weeks.

MESII-WORK OF MOSS OX THE FOREST FLOOR. Except for the ponds, most of the habitats so far discussedbelong to the open country westward from Kodiak. In theshelter of the forest to the eastward, the conditions for thegrowth of seedlings are much more favorable-. - Kodiak stands at the line separating the great Pacific coniferous forestfrom the open grassland beyond. For a discussion of the ecological aspects ofthis transition see: Griggs, R. F. Observations on the Edge of the Forest in theKodiak Region of AJaska. Bull. Torr. Bot. Club. 41: 381-3S5. 1914. 4() The Ohio Journal of Science [Vol. XIX, No. 1,. Photograph by B. B. FultonMASSES OF MOSS ON THE TREES NEAR moss balls held quantities of the falling ash which have since been consol-idated and bound in place by the growth of moss. Nov., 1918] Recovery of Vegetation at Kodiak 47 The trees themselves were but little affected by the ashfall, although their branches were heavily loaded, and in placesstill retain considerable ash. (See page ). In the deeperparts of the forest the branches bore great masses. of moss,which, of course, caught and held quantities of ash. Duringthe interval that has followed the moss has grown out over theash, making larger masses than ever and giving the trees avery bizarre appearance. (See page 46).
