The following persons have been employed on the Survey 

 since its commencement : Professor W. H. Brewer has had 

 charge of the Department of Botany and Agricultural 

 Geology, and has also occupied the post of Principal Assist- 

 ant, having had charge of the party in the field during my 

 absence. We have been assisted in the field-work by Messrs. 

 Clarence R. King and Auguste Remond, both of whom have 

 rendered efficient and valuable service as volunteers, the 

 former during part of the last year and during the season of 

 18G4; the latter at various times, and especially in the sum- 

 mer of 1862. It is hoped and expected that one or both 

 these gentlemen will be permanently attached to the Survey 

 during the remainder of its continuance. Mr. C. Averill 

 was also connected with our work from its commencement 

 up to February, 18G3, as clerk, commissary, and barometrical 

 observer. In the Topographical Department, Mr. C. F. Hoff- 

 mann has been employed from March, 1SG1, up to the pre- 

 sent time, with the exception of a short interval during the 

 early part of the current year. Mr. V. Wackenreuder has 

 also rendered assistance in this branch of our work, durins 

 the seasons of 1862 and 1864. In the PalaBontolosncal 

 Department, Mr. W. M. Gabb has been regularly employed 

 as Palaeontologist to the Survey, since the beginning of the 

 year 1862; he also acted as Assistant in the field-work 

 during a part of the season of 1862. Dr. J. G. Cooper has
