Section at Hamilton. 

 The electric railway between Grimsby and Hamilton 

 runs close along the foot of the escarpment thus affording 

 interesting glimpses of the cuesta to the left and the fruit 

 lands to the right. At Stony creek an excellent section is 

 presented, at which Cataract fossils may be obtained in 

 abundance. The section at Hamilton is best seen by as- 

 cending the escarpment at the "Jolly Cut." This section 

 is similar to that at Grimsby, but the various formations 

 appear in different thicknesses, the Rochester and Clinton 

 being greatly reduced.
