Wisconsin ice-sheet we may understand their weathered and ! 
indefinite condition. 
Few of the striated areas present much variety in direction. In 
only a couple of cases is there sufficient discordance to suppose I 
that the scratches are not contemporaneous in origin. South- | 
east of Moravia between the 1400-foot and 1500-foot contours | 
there appear to be two sets of striae, one of which averages S. | 
72° E., and the other S. 41° E. On the rim of the Montville ;| 
valley, where it drops into the Moravia valley, we also find dis- j; 
cordant striae, one set of which has the direction S. 51° E., and || 
the other S. 26° E.; the first mentioned set evidently represents j| 
the more general movement of the over-riding ice, while the second I 
is plainly the result of local topography. li 
About a mile southeast of Sempronius in a saddle between two || 
prominent rock hills we find conclusive evidence of a minor tongue i| 
which fed across and through this sag. The vigorously striated 1 
surface here gives an average reading of S. 76° E., while the valley ; 
to the west obviously directed the ice in a general southeastern j 
motion. A similar instance is also noted southeast of Nubia | 
where the striae average S. 73° E. | 
One mile west of Locke is an area which apparently gives us 
the motion of the general ice mass. The average course of the 
striae here is S. 44° E. If these striae were connected with the out- 
moving-ice from the Moravia lobe their normal direction would 
be a similar deflection to the west. There is no evidence at all 
showing that the Owasco valley ever induced a lobation of the 
ice-front sufficiently strong to offset the controlling influence of 
the Cayuga lobe. 
Grouping the direction of striae according to ranges in altitude ; 
it is seen that those found below the iioo-foot contour average | 
S. 39.2° E.; those between 1100 and 1400 average S. 52.6° E.; | 
between 1400 and 1700 the average direction is S. 69.3° PA; while ' 
the only striated surface above 1700 is the indefinite one already 
alluded to where the direction is S. 45° W. 
The following table gives a condensed resume of the principal 
striated areas arranged according to altitude; each direction repre- 
sents the average of a great many individual readings:
