INTRODUCTION 



Between the years 1886 and 1890 Enrique Abella y Casariego ^ 

 carried on geologic investigations in the Island of Panay as- 

 sisted by d'Almonte. The report of his work embraces detailed 

 descriptions of the general geologic features of the country, 

 including orography, hydrography, with the altitude of all the 

 principal points, followed by chapters dealing with the volcanic 

 formations and their "tufas." There are also chapters dealing 

 with the sedimentary formations, particularly the Tertiary series, 

 and the work closes with a part devoted to the economic geology. 

 It is very complete as far as it goes, but omits many important 

 points, which is to be expected when the geology of an unknown 

 country is treated for the first time. 



Mr. Maurice Goodman, formerly of the Bureau of Science, 

 touched at a few places on Panay in the latter part of 1905, about 

 fifteen years after Abella. The purpose of his trip was to dis- 

 cover workable deposits of sulphur, gypsum, limestone, building 

 stone, and placer gold. His stay in Panay was less than ten days. 

 He found no deposits of either sulphur or gypsum, but the time 

 was all too short properly to pass upon the mineral resources 

 of any district. Mr. Goodman obtained several specimens of 

 limestone from various points in the eastern part of Panay, the
