_MR. PIERRE LORILLARD._
Who deserves the thanks of the students of American Archæology more than
you, for the interest manifested in the explorations of the ruined
monuments of Central America, handiwork of the races that inhabited this
continent in remote ages, and the material help given by you to Foreign
and American explorers in that field of investigations?
Accept, then, my personal thanks, with the dedication of this small
Essay. It forms part of the result of many years' study and hardships
among the ruined cities of the Incas, in Peru, and of the Mayas in
Yucatan.
Yours very respectfully,
