and that the poles have always been situated precisely where
they are today. As the inquiry grew, many students made
valuable contributions to it, in research papers. Among these
I may name, in addition to Warrington, William Lammers,
Frank Kenison, Robert van Camp, Walter Dobrolet, and
William Archer.
Our inquiry first took organized form as an investigation
of the ideas of Hugh Auchincloss Brown, and I am deeply
indebted to him for his original sensational suggestion that
icecaps may have frequently capsized the earth, for many suggestions
for research that proved to be productive, for his
generosity in sharing all his research data with us, and for his
patience in answering innumerable letters.
In this early stage of our inquiry, when I was in every sense
an amateur in many fields into which the inquiry led me, I
received invaluable assistance from many specialists. These
included several members of the faculty of Springfield Col-
lege, especially Professor Errol Buker, without whose kindly
sympathy our inquiry would have been choked in its infancy.
Assistance with many serious problems was received from
Dr. Harlow Shapley, of the Harvard Observatory, Dr. Dirk
Brouwer, of the Yale Observatory, Dr. G. M. Clemence, of
the Naval Observatory, and a number of distinguished spe-
cialists of the United States Coast and Geodetic Survey.
Our inquiry, in its third year, was involved in a difficulty
that appeared to be insuperable, and from this dilemma it
was rescued by an inspired suggestion made by my old friend
James Hunter Campbell, who thereafter became my constant
associate in the research project, and my collaborator. I must
give credit to him for having taken hold of a project that was
still an amateur inquiry, and transformed it into a solid sci-
entific project.
When Mr. Campbell had developed his ideas far enough to
assure us that the idea we had in mind was essentially sound,
it became feasible to submit the results of our joint efforts to
Albert Einstein, and we found him, from then on, a most
sympathetic and helpful friend. Throughout an extended
