Current Action in the Ordovician. — Muedenianu. ;]77 
Farther up appear shales with Diplo(iraptiifi priatis, arranged in a N. 
80 degrees E. direction. 
Another exposed layer showed the same fossils arranged in two direc- 
tions, viz: N. 80 degrees E., and S. 80 degrees east, indicating a change 
of 20 degrees in the direction of the flow. 
Then a series of 19 layers was observed, which were densely covered 
with graptolites. The general bearing was N. 80 degrees E. 
Near the falls two layers were found to be striated with specimens of 
Di2)l.ograptus prisiis in ii due west direction, and above the falls two 
layers with the same fossils, pointing' S. 80 degrees E. 
Farther up the writer met with layers containing rhabdosomes of 
CliinacograptuH typiadis arranged in a N. 50 degrees E. direction, and 
a flow structure, indicating a flow from N. 80 degrees E. 
The average bearing of the graptolite? along the Flat creek 
is N. 80 degrees E. 
In the beautiful gulf of the (Utnajoharie creek one passes 
at first over Trenton limestone with wide and huge ripple- 
marks. In the shale, many long parallel drift-lines of fossils, 
one of which measured over seven feet, were first noticed. 
The direction of the drift-lines indicates a llow from (^lae 
east. 
Farther up a layer with numerous specimens of Climacogra:ptus typi- 
calis in a N. 80 degrees E. direction appeared, then drift- lines of trilo- 
bite fragments, V)rachiopod shells, etc., indicating a flow from N. 50 de- 
grees E., overlaid by layers with flow structure towards due west. 
Then two layers striated with CUviacograptus, bearing N. 80 degrees 
E., and two layers with the same fossils in N. 70 degrees E. direction. 
Farther up only one more layer with graptolites came to notice and 
the fossils in it showed no arrangement at all. 
The average direction of tiie fossils is also liei-e, as at Spra- 
ker's, N. 80 degrees east. 
In the bed of the Ofsfjiaii/o creek, near Fort I'ffdn, below 
the old cheese factory, layers of Utica shale were found, with 
specimens of Climacograpfus and Endoceras, the bearing be- 
ing N. 50-80 degrees E. 
In a small exposure, on the right bank, above the factory, layers full 
of DiplogruptuH prist in \\ end iound. The graptolites were mostly de- 
posited in drift lines about one foot long and indicate a flow from N. 70 
degrees E. 
Farther up, in the bed of the creek, widely exposed, layers were oIj- 
served which are densely covered with rhabdosomes of Diptoynijttus 
pristis hardly varying from N. 60 degrees E., while another layer abov(> 
showed no general direction, but had quite a number of rhabdosomes 
directed toward the southeast.
