Sticky slides were exposed more or less throughout the summer of 1950 in widely scattered arctic and other northern areas including Point Barrow, Alaska, northern-central Baffin Island, Jan Mayen Island, and Spitsbergen. Although the spora were generally sparse and conclusions must be regarded as tentative, it appeared that near ground level the incidence of pollen grains tended in general to coincide with the main period of flowering but that moss spores were in the air more or less throughout the growing season. Most (but by no means all) of the pollen observed could have been of local origin except in Spitsbergen, where there tended to be a preponderance of abietineous winged grains (mostly of Pinus) which were persistently caught practically throughout the brief summer although they had evidently been blown in from at least several hundred miles away.
