3no end of strength & growing expanding vigor in that latitude & soil, under fair conditions. I asked Fernow why the Sitka Sp. forest did not keep on West He mumbled a lot of stuff about prevailing winds, competition of Alder bushes & rank grass, & the "Japan Current" which simply meant he didn't know. The simple explanation is fire. The line of demarcation between the western treeless & forest regions to the eastward shows plainly that fire is the controlling agent. Most of the soil is volcanic & supports a dense lush growth of fire-feeding grass & brush. & I was told at Unalaska that notwithstanding the wet weather fire ran in the grass any time of year after a single day of dry sunshine & that constant care & fighting were required to save the [fir?] trees planted at Unalaska at Prince Williams Sound at the head of a cold icy fiard I found a pure forest of Patton Hemlock at sea-level, trees 2, to over 3 feet diameter, & 80 to 100 ft high. Bark pale gray-almost white. Pistillate flowers very dark blue 3/4 inch long. The grandest oldest mossiest Patton hemlock forest I ever saw. Waving long
