the Warrior and up the Alabama rivers, made by L. C. Johnson 

 and myself at the joint expense of the State and National Sur- 

 veys, during which we collected the data for the first attempt at 

 the stratigraphy of the Cretaceous and Tertiary formations of our 

 Coastal Plain. The greater part, however, of the material after- 

 wards brought together by the writer and published as Bulletin 

 No. 43 of the U. S. Survey was collected in the following seasons, 

 1884-5-6, by the Alabama survey alone, by Messrs. Langdon, 

 Aldrich and myself. Mr. Langdon afterwards carried these exam- 

 inations across the state to the Georgia line, and thence down the 

 Chattahoochee to Bristol, Fla., when he made the discoveries of 

 the Chattahoochee and Alum Bluff series of Miocene formations, 

 which have since become famous localities. 



Although the joint trip of the present writer and Mr. John- 

 son, above mentioned, occupied only two weeks' time, Mr. John- 

 son was afterwards assigned by the U. S. Survey to independent 

 work in this territory, especially in the examination of the post- 

 Eocene formations, and it is to his work that we owe the greater 

 part of our knowledge of the Grand Gulf and Pascagoula Mio- 

 cene of this state. Mr. Johnson was also for one season in the 

 employ of the state survey in completing the work thus begun. 

 The present writer has also spent an additional season in this 

 territory in 1891, and the coastal plain report above alluded to 

 will contain the notes from all these sources. 



It was feared by many that the extension of the U. S. Survey 

 into the territories of the older states would have the effect of 

 preventing the organization of new state surveys, and of causing 

 the discontinuance of those already in existence, but the con- 

 tinuance or completion of existing surveys in New Jersey, Min- 

 nesota, Illinois, Indiana, Pennsylvania, Kentucky, Alabama and 

 Wisconsin, and the- organization of new surveys in Texas, Arkan- 

 sas, Missouri, Georgia, North Carolina and Iowa show that these 

 fears have not been fully realized. The national and state sur- 

 veys occupy practically somewhat different ground, and so far 

 from being antagonistic, they should be mutually helpful. In 

 the case of Alabama it may be asserted that the cooperation of
