Thames river, Connecticut, seems to have a small but typical 

 bav tide. There are but two observation stations. 



CONNECTICUT TIDES 



The Connecticut has its mouth in the sand-bar region of the 

 Middle bay, and itself discharges no small quantity of sediments, 

 that make its exit to the sound an embarrassed one. Tide pro- 

 gresses up to Hartford (43 miles) in 4 hours and 48 minutes, with 

 fairly constant speed, the ranges steadily diminishing.

The stream is narrow, from a quarter to three-quarters of a 

 mile, and shallow. The local geography affords a rational ex- 

 planation for the lack of the "bay." The lower course of the 

 river is cut in rocks so much harder than the upper course that 

 the lower valley was gorge-like before drowning. The departure 

 from the via type is in the lack of uniformity of rock texture 

 along the river. 



HUDSON TIDES 



The Hudson also flows in a narrow gorge in its lower course 

 and has no bay nor bay tide. Nearly as narrow as the Con- 

 necticut, but deep, it allows a more rapid transmission of the 

 tide wave. The 141 miles to Albany are traveled in 10 hours 

 and 8 minutes.
