Report of a Reconnaissance in Trans-Pecos Texas, North of the Texas and Pacific Railway

INTRODUCTION: The reconnaissance reported upon in the following pages was undertaken primarily to determine the conditions of occurrence of underground water. The area studied is situated in Western Texas between the Pecos River and the Rio Grande, and extends from the Texas and Pacific Railway northward to the New Mexico boundary (Plate 2). It includes about 9000 square miles and is somewhat larger than the State of Massachusetts. Six months, from June to December, 1903, were spent in the field. Dr. Wm. B. Phillips, Director of the University of Texas Mineral Survey, offered every facility at his command for the furtherance of the work. Messrs. C. D. Walcott, T. W. Stanton, G. H. Girty, and E. 0. Ulrich kindly examined the paleontologic collections, and Mr. E. H . Elder, a student in the University of Texas, assisted for three months in the field. -- G. B. .RICHARDSON.
