Shakespeare's Cliff and Cape Grinéz, in France, is one hundred and eighty feet; and Guyot says that "the Baltic Sea has a depth of only one hundred and twenty feet between the coasts of Germany and those of Sweden," and "the Adriatic between Venice and Trieste has a depth of only one hundred and thirty feet." A pond in my native town, only half a mile long, is more than one hundred feet deep.

At midsummer you may sometimes see a strip of glassy smoothness on it, a few rods in width and many miles long, as if the surface there were covered with a thin pellicle of oil, just as on a country pond; a sort of stand-still, you would say, at the meeting or parting of two currents of air (if it does not rather mark the unrippled steadiness of a current of water beneath), for sailors tell of the ocean and land breeze meeting between the fore and aft sails of a vessel, while the latter are full, the former being suddenly taken aback.
