376 THE CARLISLE EARTHQUAKES OF JULY 1901. [Aug. 1902, 
The northern part of the focus was smaller than the other, but was 
marked by a much stronger impulse. ‘The stress in this portion of 
the fault was not, however, completely relieved by this displace-. 
ment, for, 3 minutes afterwards, another slight slip occurred there. 
The third slip, about 20 minutes later still, was complementary to: 
the first, for it appears to have occupied the whole of the region 
between the two principal portions of the first focus, and to have 
been greatest near the centre of that region and gradually dimin- 
ishing towards both ends. A little more than two days later, a 
very slight movement occurred in or near the southern part of the 
first focus, and the series of movements, if we may rely on solitary 
observations, concluded with some small slips near the central part. 
of the intermediate region of the fault.’
