INTRODUCTION 
According to arrangements between the Department of Public 
Works of the Republic of Haiti and the United States Geological 
Survey, a geological reconnaissance of the Republic of Haiti was made 
in the winter of 1920-1921 under the supervision of the United States 
Geological Survey. Mr. J. S. Brown, Mr. W. 8S. Burbank, and I 
arrived in Port-au-Prince on October 1, 1920. We were in the field 
continuously until April 15, 1921, when we sailed from Port-au-Prince. 
We made a general reconnaissance of the entire Republic, including 
Gonave Island and Tortue Island. A detailed reconnaissance was 
made of some regions in order to obtain information on certain 
mineral deposits and on underground water resources. The highest 
and most inaccessible parts of some of the rugged mountains, such as 
the Montagnes Noires, the Montagnes de la Selle, and the Montagnes
