INTRODUCTION 
The senior author's interest in Gaspe region was first aroused some 
twenty-five years ago, in the course of a discussion with the late Professor 
Henry S. Williams, then in charge of Devonian correlations for the United 
States Geological Survey, as to whether the lower Helderberg was Silurian 
or Devonian. The statement had, long before, been made in print that 
at Arisaig, Nova Scotia, the Silurian passed unbroken into the Helder- 
bergian and that the whole was beneath the Old Red Sandstone equivalents. 
It had also been stated that about Gaspe, Quebec, there was a complete 
succession from the higher Silurian into the most interesting Devonian 
section anywhere. Schuchert, therefore, concluded that it would be well 
to see these places, and in 1900 the United States National Museum made 
it possible for him to study and collect fossils from the fine sections at 
Arisaig, Dalhousie, and Gaspe peninsula. 
These localities had also attracted the attention of the late Dr. John 
M. Clarke, of Albany, who, when informed of the prospective trip, expressed 
a desire to accompany Schuchert, and the two were in the field from July 11 
to August 8. From that time until his death Clarke returned to Gaspe 
almost annually, and the results of his observations in this country, 
which he came to love so dearly, form the subject of many geologic 
and palseontologic papers. Not only this, he became the historian of 
Gaspe and Chaleur bay, and has recorded in two most interesting books 
human happenings in this region since its discovery by Jacques Cartier 
in 1534.
