Alternate Title

Notes, 1871, W.H. Dall, USCS


The field book documents William Dall's fieldwork in Alaska in 1871-1872 when working for the United States Coast Survey. It lists specimens collected by survey participants including mammals, birds and shells; detailed descriptions of observed specimens with measurements; geological characteristics; and terrain. Includes sketches of terrain, specimens, and geological cross sections. There are various kinds of lists including birds and mollusks of Unalaska and Arctic fauna (with Latin names). Locations include the vicinity of Ulakhta Harbor [Dutch Harbor], Unalaska, and Round Island.

P. sandwichensis [[end page]] [[start page]] well back. with ^ [[insertion]] flesh [[/insertion]] red feet flew around the vessel and lighted on deck today The species is I feel quite sure the same which I called P. savanna in my Alaska Catalogue. The nearest land is five hundred and fifty miles off the wind N.W. not very strong but has been blowing harder - After some trouble secure the bird and put it in a cage. Protempore skin & sternum No. 3 ____ Another land bird alighted on the ship in the evening but flew off again and was not recognized in the darkness. Saw several gulls or Procellariae during the day. Sept. 15 a small blue fish with a double
[[blank page]] [[end page]] [[start page]] row of peculiar punctures on the abdomen was washed on board, put it in bottle No. 2. No. 4. Observing the flight, of the [[gorry?]], Diomedea [[strikethrough]] Julyinosa [[/strikethrough]] nigripes. I notice that its ordinary method of sustentation when there is a breeze consists of rising against the wind and falling with it. This being kept up sometimes for hours with hardly a single stroke of the wings. It rises only against the wind except in rare cases when its decending momentum is sufficient to raise it slightly for a short distance or when the reflex eddy from a high surge is strong enough to give it a slight lift. It uses its broad webbed
feet to some extent in balancing itself when turning with the wind, also by poking them down at a right angle with the body to check its course especially when alighting on the water. Generally while flying they are stretched out behind with the webs extended and assist the bird materially in guiding itself, the tail being shorter than the extended feet. It rises by extending its wings and running against the wind over the water until it is sufficiently raised above the water to use its wings without wetting them. A flock of four or five have accompanied us from California so far but will probably soon leave
[[blank page]] [[end page]] [[start page]] us, as I have noticed that they do not go north of the Aleutian Islands. Their eyesight is exceedingly acute, they can distinguish a discolored spot a yard across, in the water, from a distance of at least ten miles ^ [[insertion]] and even [[/insertion]] much further than our unaided eyes can see the bird itself. Its flight in calm weather consists of a series of about five or six short sharp strokes at intervals of a second or more apart followed by a short period of comparative quiescence.

Find the rocks south & east of captains Harbor to be all masses of Syenite [[insertion]] 9 - 10 [[/insertion]] with a perpendicular dip. and
[[blank page]] [[end page]] [[start page]] cleavage planes in every direction in mountain mass 800 to 2000 ft. high. Ascend some of these and find nothing but syenite in every direction over laid conformably by thin beds of clay and sand with hydrated peroxide of iron in some places a very superficial & very recent formation containing decayed leaves of grass & other vegetation of recent origin. These clay beds were insignificant in extent and limited to small depressions in the mountain tops. Found the so called Amber Lake which was a small pond on top of a syenitic mountain about 2000 ft above the sea. No signs
[[blank page]] [[end page]] [[start page]] of any tertiary deposites. There were three lakes - one discharging into Lake Sarycheff and another into the third which emptied on the other side of the divide apparently in to Beaver Bay.

The round island is of similar rock. Examine the Acmaeas now April 5 in full season. The milt is milky, with sacs yellowish cream color.

The most mature are free floating in the fluids of the animal close to the Anal papilla and I have little doubt that they are extruded by the so called renal orifice though I have not yet definitely traced the oviduct. At no other point in the ovisac are mature ova found. The color of
There are two small red glandlike bodies one on each side of the neck which I have not seen in alcoholic specimens. There is but one renal sac hence probably no renal orifice. The funnel shaped extension of the ovary runs along the cloaca for some distance but does not open into it as far as I can discover. The renal sac is composed of vermiform yellowish green or olive blind [[occuli?]] branching and curling in every direction and opening into a common duct. The young 1/50 of an inch long and translucent brown dish shaped no spiral nucleus. [[end page]] [[start page]] the distended ovisac is orange brow, darker towards the anterior end. There are no capitopedal orifices. I could not detect the renal orifice / A. patina (or testudinalis?) but traced the mature ova through a very tender duct or membranous canal, to the left of the anal canal, close to where the renal orifice must be. There are two orange-red prominences, behind the head, one of each side of the neck - can't imagine their nature or office - have seen nothing like them in alcoholic specimens. Animal yellow white except dark tentacles and mantle edge foot yellower & redder - Muscles of buccal parts red - bill short. These grow very large on the rocks here.

The strata at the surface are metamorphic sandstones & slates generally dipping to the westward but arranged in waves having their longer axis about NNE & SSW. sometimes faulty but in general pretty regular and occasionally an exposure perpendicular to the axis shows the wave complete & unbroken. The slates & sandst.
