868 2'he American Geoloymt. Juno, 1897 
moving water, show a general E. N. E.-W. S. W. bearing in 
the Utiea shale of the Mohawk valley.* 
Section on^/irst curve of East Canada Creek, I)elow DoUfeville. 
The rock is thin-bedded shale and slate with occasional in- 
tercalations of thin calcareous bands. 
1. Four layers of shale, with crinoid joints, sponge spicules, speci- 
mens of Clinuicogrnptns bicornis and a few EndoceraH shells. Bearing 
of all, N. 70 degrees E. The apices of the Endoceras shells point E. 
2. Above a layer covered with fragments of Triarthru.s, all directed 
N. 60 degrees E. 
Fourteen surfaces of shale exposed, with sponge spicules. Diplogyap- 
tiis pristis and EndoceraH. Bearing, N. 60-70 degrees E. Graptolites 
jHiint E. with the sicular ends and Endoceras shells with the apices. 
Bank of limestone (without fossils). 
3. Shale with fragments of Trkirtlirns, all directed N. 50-70 degrees 
E., giving the slabs a furrowed appearance. 
Eight surfaces with prevailing sponge spicules, a few Diplogruptus 
pristis and Endoceras, ah pointing N. 50-70 degrees E. Apices of En- 
doceras shells E. 
Layer with sponge spicules and numerous rbabdosomes of Climaco- 
(jraptus hicornis. Bearing, N. 65 degrees E. Sicular ends of most 
stipes west. 
Calcareous bank, without fossils. 
4. Eight layers with numerous specimens of Endoceras. Bearing, 
N. 70 degrees E. Apices E. 
Layer with trilobite fragments, numerous specimens of Climacograp- 
tus and some Endoceras shells. Bearing, N. 50-60 degrees E. 
Layer with Climacograptus hicornis. No direction. 
Layer with Climacograptus and Endoceras. Bearing, N. 70 degrees 
E. Fourteen shells of Endoceras were counted pointing east, two west. 
Apices of Cliniacograpdus in both directions. 
Numerous layers with DipJograptus prisiis and Climacograptus. 
Bearing, N. 60-70 E. Sicular ends mostly west. 
Calcareous bed, without fossils. 
5. Four layers full of sponge spicules. Bearing, N. 80 degrees E. 
*It is to be remarked that layers which yielded no fossils at alJ or on- 
ly single specimens of the displaceable fossils have not been mentioned: 
further that among the given bearings are certain ones to which the 
fossils are almost mathematically parallel (especially in certain layers 
near Dolgeville and on Otsquago creek), while in other layers thei-e is 
only a general, thovigh distinct tendency to arrangement in a certain 
direction. In the latter case the limits of the directions have been 
given. It is evident that the differences in the regularity of the ar- 
rangement are due to differences in the velocity of the moving water. 
The approximate value of 10 degrees for the present western mag- 
netic declination of the needle in the middle Mohawk valley has been 
used for the correction of the readings.
