NOTES ON TAHITI 953 Photo by Harrison W. Smith LOOKING DOWN THE FATAUUA VALLEY FROM THE STEEP TRAIL WHICH LEADS THROUGH THE TROPICAL FOREST TO THE FATAUUA FALLS, OVER 600 FEET IN HEIGHT As the difficulties of photographic work in the tropics are well known, it may be of interest to describe a conveni ent feature of the writer's outfit-the dark-room for plates. All plates were given the 20-minute pyro development in the Eastman tank, according to the Eastman formula. Page 962 shows a suit-case that formed the body of the dark-room. The right half is occupied by a water-tight rubber bag, supported on three sides by the sides of the suit case and on the fourth by a brass rod, which may be seen extending over the edge of the case and hooked into the lock. The developing tank, filled with developer at a temperature sufficiently below the normal to allow for rise of temperature before development begins, rests in this rubber bag, as shown. The object of the rubber bag is to prevent damage to plate-holders that are placed in the other half of the suit-case in the event of the tank spilling over. The cover of the suit-case is held up by means of a light wooden rod at each corner, and a dark bag is then placed over the whole. The other illustration shows how two long sleeves permit the operator to trans fer the plates from the holders to the tank without the necessity of himself being in the confinement of a dark-room, a distinct convenience' in the tropics, even. on the rare occasions when a dark-room is available.
