{15} This is thus chronicled by M. Ruppen: "1589 den 9 September war
eine Wassergrosse, die viel Schaden verursachte. Die Thalstrasse, die
von den Steinmatten an bis zur Kirche am Ufer der Visp lag, wurde ganz
zerstort. Man ward gezwungen eine neue Strasse in einiger Entfernung vom
Wasser durch einen alten Fussweg auszuhauen welche vier und einerhalben
Viertel der Klafter, oder 6 Schuh und 9 Zoll breit soilte." (p. 43).

{29} Mr. J. T. Cunningham, of the Marine Biological Laboratory,
Plymouth, has called my attention to the fact that I have ascribed to
