362 Geological Survey of Great Britain. 



tratioDs in Pal je ontology by Mr. Salter, on Mining and Mineralogy 

 by Professor Smytbe, on Chemistry by Prof. Hoftnan, on Physics 

 by Prof, Stokes, on Mechanics by Prof. Willis, and Metallurgy by 

 Dr. Percy. Plan and machina drawing, <fec., are also taught. As 

 a necessary result of these operations we have turned out from this 

 school a number of young men who, in geology whether practical 

 or scientific, are beginning to distinguish themselves. Those who 

 get the best certificate are appointed to the Geological Survey, 

 whenever there is a vacancy, if they wish to follow geology as a 

 profession. This year three new assistants were in this manner 

 sent into the field to be trained for conducting field operations. 

 As Director for Great Britain I have thirteen assistants, three of 

 them are senior Geologists. They have served a number of years 

 to get up to that rank on the Survey, perhaps from eight to sixteen 

 years. I have eight assistant-Geologists, younger men who have 

 come on the stafi" and are struggling to attain some standing in 

 their profession. There are two others whose chief duty is to collect 

 fossils under my direction or that of any of the officers in the staff, 

 under whose charge I may chance to place them. When a young 

 man comes in I place him on the secondary strata — the tertiary 

 strata being too obscure — and after they have laboured on'these 

 comparatively horizontal strata, in which the lines are compara- 

 tively easily traced, they are transferred to the paloeozic districts. 

 In Ireland the same system with an independent staff is pursued 

 tmder the direction of !Mr. Jukes. These are all the field officers 

 employed on the Survey, but in addition to that we have two 

 palaeontologists in Jermyn Street, whose duty is to receive all the 

 fossils, examine them, label them, describe and figure them, and 

 if necessary to go into the field and give advice in regard to criti- 

 cal points in palaeontology. The maps we work upon are the 

 Ordnance maps. These maps we apply for, and every surveyor 

 takes one or two copies of the district he is in charge of^ and traces 

 the geological lines upon it. In this map (pointing to a small 

 quarter sheet map) there are no fewer than eighty geological lines 

 traced. The mountains in this map, are most of them over 2,000 

 feet highj some of them more than 3000 feet in height. In this 

 map the geological lines of all the different formations are traced. 

 On the maps heretofore published, no fewer than 125 formations, 

 or modifications of them, are indexed by the colors employed, and 

 each of these formations, &c., is traced foot by foot on the ground 

 with many ramifications. The maps used heretofore in England
