But even this reduced estimate must be excessive.

Except in the Bristol Channel there is no rise of tide in the seas of Northern Europe which at all approaches this limit.

At Reikiavik (Iceland) the rise is seventeen and a half feet.

In Greenland it varies from a minimum of seven feet at Julianshaab to a maximum of twelve and a half feet at Frederikshaab.] CHARACTERISTICS OF COLUMBUS Considering how much more real the hero of a biography appears if we can picture him accurately in our mind's eye, and see him "in his habit as he lived," it is singularly unfortunate that the personal appearance of Columbus has been so variously described by the old historians that it is impossible to speak with certainty on the subject.

Strangely enough, too, no well-authenticated portrait of the great discoverer exists.
