. The earth and its inhabitants .. . 79° West oP Grppnv-MrV, Olo 16 Feet. Depths. 16 to 32 Feet. 32 Feet anl upwards. 12 Miles. American side, so that the southern part of the bay cannot fail, sooner or later, to be cut off from the open sea. The contrast between the Atlantic and Pacific seaboards is primarily due to the tides, which vary far more on one side than the other. At the mouth of the Chagres river and in Colon Bay there is a mean rise of 15 inches, and of one foot in Chiriqui Bay, but this difference between ebb and flow is not constant, being greatly modified according to the force and direction of the winds. At times the surface remains at the same level for days together ; but as a rule the two diurnal tides neutralise each other so far as to produce only a single rise and a single fall in the twenty-four hours. On the Pacific coast, on the contrary, ebb and flow follow the normal course.
